Germinating seeds.

We have been working on our five acres and have done seed collection and are now germinating seeds in the hope we will have plants to plant in spring.

We have begun replacing imported grasses with native grasses which is time consuming and hard work, with a good germination of our barb wire grass seeds we should be able to create quite a good sized area of it in our front yard.

We will be also planting sections with kangaroo grass, wallaby grass, and blue falx lilly.

Along with that we have many shrubs and trees growing including forest red gums (which took a while to find), tallowood, she oaks of a few varieties, bottle brushes, grevillea, and various small plants such as correa and native mint bush.

We are aiming for a layered look throughout the yard that will include grasses right through to long lived trees in the hope f providing good habitat to birds and animals.

I have managed to photograph 43 species of birds on our property so far and am still working on photographing many more. So far the species photographed are range from yellow thornbills, and red browed finches, to olive backed oriole and many kinds of parrot as well as the ferals.

I am growing more and more anxious to see our garden grow and provide more habitat as I see Penrith growing out to meet us.

I urge all bird loving people to do likewise and plant what you can when you can.

What a marvelous ( in memory of Richie Benaud) project, Wollemi. I'll be interested to learn if you find that native herbs are regenerating among your other native plants.

I'm particularly interested to read that you're germinating seeds at this time of year ready for planting in spring. When I grew my indigenous plants through Trees for Life in SA I sowed seeds in November & the plants were ready for putting in the ground by late autumn. This timing meant that the trees & shrubs benefited from winter rain & most were able to survive summer without the need for water from me. Do you usually get good summer rains where you live?

I have had success with Spring and Autumn plantings. Autumn plantings are good but the plants have to wait a while for the chance to grow, spring plantings can take off very quick. I collect seed myself, things like eucalypts and wattles are quite easy, I haven't had to grow grass as we have lots of native grass here. My approach is to plant lots of things every year, sometimes they fail but sometimes the results are very rewarding, and the birds love it.

It's ok to water things to get them through their first few seasons. most natives will be fine once they get established.

Hi, Greg. I think the reasoning behind planting in autumn is that plants make root growth in winter then put on a spurt once the weather warms up in spring. The winter root growth means that little or no watering is needed in summer. 

I've had relatively good success by broadcasting seeds of a few species. That has saved me lots of work & water but, of course, there's lots of seed wastage.

Plant roots don't grow much in winter, the time of most root growth is spring followed by some root growth in Autumn. In summer the soil is too dry, in winter too cold. I don't sow seed direct, I sow seeds in pots and prick out into tubes. I don't see a problem with watering new plants through the summer if it isn't too hard to get water to them.

heaps of natives grow in winter in mediterranean and dry summer climates.

Apart from time, effort & cost the problem I have with watering is that SA is the driest state in the driest continent outside Antarctica so water is a hugely precious commodity here. Also, I note that water is becoming an enormous problem in Australia with increasing numbers of humans using it in increasingly profligate ways, not to mention the influence of climate change on droughts. Therefore, water conservation is a big issue for me.

On the root front, my understanding is that the roots of Australian natives, especially Eucalypts, generally grow fast & deep as soon as the seed germinates or the plant goes in the ground. I recall seeing a demonstration of this in a container with a glass side. The tap root growth was about 5 times the growth of the plant above ground. But I'm not sure at what time of the year the demonstration was conducted. Perhaps it was in spring. Whatever, I'm delighted with the low losses of my plantings when I plant after season's break (usually in autumn) & don't water in summer. Perhaps this approach is more applicable in SA's climate than elsewhere.

It holds true in summer-dry parts of victoria also. 

council and reveg operators often plant reveg projects when the autumn break occurs.

Mature trees usually do not have taproots except some desert adapted species which access ground water. most species are shallow-rooted.

It was indeed my intention to germinate seeds in Spring and plant them in Autumn with protective guards for their first Winter in the ground. However after seed collection, life got in the way so the seeds have been waiting a little while to have their chance.

I do direct sow seeds in garden bed, and this is the most ineffective use of seed as it has a very low germination rate, but I do tend to just cast excess seed out over the garden beds and let grow what wants to grow and figure the rest of the seed adds to the mulch or becomes food for birds.

We are hoping that by nursing these seed/lings through winter we can plant in early spring and know we will have to water them, but we are prepared to do that to get them through,(except the grasses which we will plant in a couple of weeks out in the area we have prepared.)

In the past I have germinated in the spring and planted in the autumn but lost a good percentage of plants when we had colder than usual frosts. So it would seem there are good and bad reasons for doing either way.

I think it very much depends where you are.

In sub-tropical areas like those around Brisbane, it's generally inadvisable to plant much later than March, as it tends to be the dry season, nothing does a whole lot of growing and young plants can often get water-stressed and die.

This is particularly an issue if you're trying to establish rainforest plants. For sclerophyll/eucalypt forest stuff it's less of an issue, but I'd still be reluctant to plant too much at this time of year.

That said, our local bushcare group is having a planting day this weekend, and our native plants group has 2 autrumn sales coming up, which tend to be well patronised, so someone is obviously doing planting here...

That makes sense to me, Tim. 

Great to hear that native plants are being bought &, hopefully, planted. (Years ago I gave two boxes of plants to an eagerly accepting neighbour & they sat, withered & died on his front verandah). Ah, well, at least the thought was there.

i find sometimes you have to volunteer to plant it for them.

Zosterops,

I wish I could volunteer to plant native plants for anyone who wants them. I really would do it. Alas, I am quite busy in my own household and volunteering in the community and I have long term chronic health issues to deal with as well.

I do find people telling me they can't grow natives because they have no gardening skill, I usually reply that is why you should grow natives because very little in the way of skill is needed to make them grow.

I do find too that a lot of people think that bottle brush tree on the footpath is the limit of the commitment required to provide habitat.

I Can not wait for the day that councils start to plant trees and shrubs other than bottlebrush so the overabundance of honeyeater food does not adversely affect all of the little less gregarious birds.

We are far from a perfect society!

Zosterops, I'm reluctant to volunteer my planting labour on a couple of accounts.

One is that I don't want to deprive my neighbour of the pleasure to be derived from getting dirt under his finger nails & working in the fresh air & open spaces, something which can become addictive. Another is that I find that dealing with my own patch is very time & energy consuming & I don't want to spread myself too thinly.

Perhaps a worthwhile compromise would have been to offer to plant the plants with him. That would have given me an opportunity to engage in discussion about matters environmental & maybe even comment on various creatures & plant features. Now that my restoration work is beginning to look after itself (a very satisfying stage to arrive at in a revegetation/bushcare project) I'll be able to offer this to him. I do note that he has excluded stock from a couple of areas where River Red Gums Eucalyptus camaldulensis are now regenerating. Slowly, slowly things happen.

I've wanted to leave a comment on this thread for a while now but am reluctant to speak my opinion about this topic. But I will say that germinating seeds is not something that happens successfully here in Tenterfield, even with exotic flowers. It seems the climate is all wrong, so I've had to change my strategy for germinating seeds. I now put seeds on a damp paper towel, throw it in a ziplock back and forget about them. This seems to work for me, and is how I'm able to germinate most of my seeds. If I plant seeds in pots or in the garden, all I get is a bunch of weeds germinating. 

Planting native plants to my area is not a problem when I can find said species but as I privately rent this place it makes me wonder how long the plants will survive before a new owner will rip all the plants out. I have a few native plants to my area that will outlive me and I refuse to plant them in the ground because at some point I know they will be ripped out by a new landlord. Knowing this frustrates the heck out of me. And to top all of that off, plants that struggle to survive in town (or are doing well at any stage of their growth) will eventually get removed for no obvious reason by vandals?/the council?.This just makes me so depressed. The attitude of people in this town toward plants in general that isn't grass needs to change. It's no wonder we rarely get any rain here with all this wide open area devoid of plant life. Just Google Earth "Tenterfield NSW" and you'll see what I mean. 

Landcare sucks here. They start out with projects then complete them but never look after any of the plants. Most to nearly all the plants they put in the ground do not survive. I feel like I'm the only person in this area that actually cares about the environment and wildlife.

My little garden with native plants in it will not make any difference at all. As depressing as it sounds, only a few older people will enjoy it's look, and a few individual birds may benefit from it when the plants are finally in flower.

How frustratingly exasperating, Hyperbirds! Teeth gritting must be one of you favorite activities. Nevertheless, you are starting somewhere which is more than can be said for many of our fellow countrypersons. What you're doing is worthwhile even if it benefits a few individual birds. 

A while ago there was a Tenterfield poster who painted a picture of the Tenterfield community very similar to the one you've described. She (I think it was a she) was very frustrated, not to mention disillusioned, too. Perhaps you know her! Anyway, she beavered or platypused away at her nearby creek, planting native species. I imagine that many

 of her plantings will now be tossing their heads with sprightly dance. (Apologies to Wordsworth). This may be something you might consider doing, especially since you've hit on a seed germination method that works for you. Perhaps you're already out there as the Phantom Planter! 

Yes, indeed, landlords aren't known for their fondness for the natural environment, especially after the rent has been paid. That's why the role of Phantom Planter in the community can be so valuable for renters who are green friendly. 

Hang in their, Hyperbirds. Tenterfield & its natural environment need you like never before.

Yes, I know the person you are referring to Woko. That person, and it is a she, is actually me, Shirley Hardy. I quit this site because I had a fallout with Araminta. S*** happens, I guess.

Of all the plants I planted along the Tenterfield Creek only 2 have survived (both of which are trees). Everything else got whipper snippered down, eaten by rabbits or got killed by ants or just didn't make it, or got mowed down by the new neighbours. The new neighbours (the female anyway) is a horrible person and I've had a fallout with her too. Now there's cows, sheep and electric fences everywhere where and their garden has gone from a moist attractive garden to a really dry habitat that Tiger snakes now like. Their dog, which I like, kills all the snakes that he sees (and gets bitten by them except by the Tiger snakes). Many of the trees have been chopped down or mutilated. Most of the birdlife has disappeared that were there just 2 years ago because it's so dry there now. I've confronted the woman about the importance of planting plants by the creek to prevent erosion of their land and she flatly doesn't give a s*** about the erosion and doesn't believe a word I say. She refuses to plant anything along the creek to prevent erosion from happening. I've just given up on it all.

I'd actually plant native plants along the creek, as a phantom planter, by there's a stupid electric fence in my way. Owners of cows now allow their cows to graze right in the creek of the left side of the Douglas Street bridge, (where I was planting was on the right side of the Douglas Street bridge) right where there's still a small pocket of native vegetation left. Its not the cows fault. Anywhere I want to plant something there is going to be a human who finds my seedlings. I've even thought about putting a Strangler Fig up a poplar tree by the creek but the poplar trees have their lower branches tidied up each year by the council? each year. I'm getting that desperate for ideas right now.

It seems the property owners around here just want their nice lawn areas and wide open spaces to look at. Well, good for them because the climate is changing and their grass isn't green anymore. It's rarely green for long before it starts dieing off. And guess what? My front lawn is green and I don't water it. I'm siding with nature now. Let the place completely dry out for all I care. Humans have brought this upon themselves!

I recently was laughing my head off when I learnt about my neighbour's second dog. My neighbour had 2 dogs (the one I had the fallout with) and 2 cows. Well, the cows were borrowed (a mother cow and calf). One day the neighbours and their dogs were in the same paddock with the sheep and cows when suddenly the mother cow went mental, stampeded and attacked the little dog. It broke the dog's spine. Within the hour the little dog had to be euthanised by the vet, as she was paralalysed from the upper spine downward. Poor dog but serves the woman right for being a b***** and anti nature in the first place. Nature just doesn't like her. I've many stories like that one in reference to her in particular. 

Leaving things well alone is the best choice I've ever made. I know nature works it's own way to get back at people. I haven't lost a single plant in my garden except for most of my snow peas, in the last 24 months. I've found better things to plant than vegetables, although I still want to plant some. I'm still working on that though. I have celery and silverbeet in my garden, and they've survived the snow, frosts, drought, rain, heat, sudden changes in temperature, etc. Awesome! Can't say that about my stupid orchids though but they're battlers as adult plants. I love nature and will always love planting native plants and other things too. What's in the ground is more than what was there before.  I just have to think outside the box, and start thinking like nature does. A slow encroachment of plants from the outside inwards. That's how natural revegetation seems to happen. 

Thanks, Woko, I now know where I can plant some plants in secret that is never touched by humans at any time of the year and where no animals graze either. I'm going to attempt to plant upstream of the creek within walking distance of my place. I'll start a post about it when I have some pics to add. I needed this rant, so thanks again, Woko.

So much effort for so little return! No wonder you're feeling angry, Hyperbirds. However, I can see that you're beginning to think more strategically. Maybe you're even adopting the "don't get mad, get even approach".

You're idea of planting where there are few insensitive humans & rampaging herbivores is the way to go, I reckon. Also, planting upstream is a good idea because when the next flood occurs (& there will be one) there'll be lots of seed transported downstream to germinate, hopefully right next to your neighbour's property!

You might also want to consider minimum disturbance bushcare as a way of encouraging the regeneration of what little native vegetation there is in your neighbourhood.

Have you thought about guards as a way of not only protecting your seedlings but also making a statement that someone is doing something to restore the environment? Photos of your plantings with follow up photos of any vandalism could be sent to the local media to highlight the degree of anti-environment Naziism in the community. Tree guards cost money, of course, but perhaps a gentle request for assistance to the local Landcare group might yield results, notwithstanding your jaundiced view of that organisation.

If you decide to use guards I recommend spraying weeds around each guard so that it is clear that the plants & their guards need to be avoided. Of course, guards & spraying won't stop the determined Earth wrecker.

Your neighbour seems to fit the anti-environment stereotype & I wonder if you need to spend less energy on her & more on thinking on & acting in the environment. A lot of time & energy can be spent on immovable objects for little or no return, time & energy which could be more productively spent elsewhere.

Sometimes, too, patience provides substantial rewards. Doing your own thing in your own quiet way may provide a model for others to eventually copy. Besides, as you seem to be aware, you can spend a lot of time plotting revenge when Nature will have its own way in the long term.

More specifically, I'm somewhat surprised that Tiger Snakes are using the dry territory provided by your neighbours. I understood Tiger Snakes are more attracted to damper areas. Perhaps they simply like the edges of creeks, rivers & streams, however dry or wet. The snake experts on Birds in Backyards may have thoughts on this.

Woko, I tend to eventually reach a point of being completely exhausted of ideas and then give up on things. But then suddenly an idea will hit me like lightning as what happened in my last comment. I will probably never give up hope on revegetating my area but my previous strategies simply don't work. The effort and time I put into this revegetating project goes, for the most part, unrewarded. Nature seems to fight me all the way but nature encourages the plants that do survive from what I've planted. Only if the plants/trees cannot be ripped out by multiple floods will they survive. The 2 trees that survived have survived 5 floods now in the passed 3-3 1/2 years and the trees are now taller than 6 feet in height. 

The upstream area I have in mind is a small strip of roadside that never is attended to. The sides of the road are never mowed, and, natural revegetation is occurring along that strip albeit slowly. I've seen Crimson Rosellas eating from the revegetated Wattle trees along that strip in the past. There's lots of grass at maximum height there as well as rabbits. Not sure if it's native to the area or not though. The road leads to a gate to someone's property. The roadside leading down toward the gate can be easily planted out with native vegetation, even with gum trees without the seedlings being spotted until they're too big to be pulled out by hand. The idea is to hide the seedlings amongst the grass and let them grow as naturally as possible in that environment. Tree guards would just make it look obvious that revegetating is happening there by me. 

Which brings me to my next point.... people notice what people give attention to in this place. I recently found another but older specimen of an unidentified tree/shrub growing that I'd dug which had germinated by a bird dispersing the seed (it's not a weed that I can tell) so I took some photos of it. It was in an empty paddock near the road. Two days later the 6 foot specimen had vanished. The ground was undisturbed and no sign of it being cut down either that I could tell. It was growing amongst grass and there was another specimen growing further back in the paddock along the fence line. If this specimen was cut down by a human then there is no way I am letting anyone local see (or know about) my future activity of tree plantings nearby. I'll be working quietly with nature to get the trees/plants established. No tree guards, no spraying weeds/grass. It will look like they just grew there themselves. 

At the moment (today) I'm doing some research on what would be a good type of plant/s to plant upstream, that not only the seeds will self germinate downstream but the birds will also relocate them elsewhere. I need multiply options for the maximum seed dispersal, and something that self germinates quickly; like the way a weed self germinates but something native to my area. 

For the past few years Tiger snakes started heading south more and last October they began popping up in people's backyards here in town. Tiger snakes have made a nest underneath my anti-environmental neighbour's old car shed in a rabbit warren, so I'm laughing my head off about that one. The Tiger snakes don't cross the road at all so I never see them at my place. I do see Red-bellied snakes (juveniles) and the odd Brown snake on our lawn. I think they're escaping from the neighbours across the road, and their snake killing dog and the livestock in their paddock.

My neighbours across the road are freaking out when it comes to the snakes as there was an Inland Taipan under their house for a few weeks last summer. It then moved on quickly. There was also a very large snake that travelled through the creek heading downstream - something really big and something like a python. The neighbour's noticed the snake trail and called out the Dept. of Wildlife here in town. Nature turns on people in all kinds of ways. I'm laughing because the more snakes that are killed in the area the more that relocate themselves to this area in the same season.

Don't give up Hyperbirds, I experience similar issues with my revegetation projects along the local creek - bored kids, motorbike riders, over eager council mowing contractors or herbicide contractors, floods, vandals etc. I check up on my plantings every couple of weeks and if it's still late Autumn, winter or early spring at the latest then I replace the destroyed plant with a new one and wish it well... over time you may lose many battles but will eventually win the war. I'm off again this weekend to replace a few plants I noticed had been destroyed by one of the aforementioned on my creek inspection last week.

It seems you're working out a few ideas for yourself, Hyperbirds. That's great. You're the one on the scene so your ideas are more likely to bear fruit (& seed) than ideas from outside (such as mine). It'll be interesting to see how they work out. Good luck & may conditions be fair to you & your plantings!

I've unsuccessfully tried growing Acacia seed in pots, even after soaking them and/or nicking them as per their requirements to get them to germinate. I had two different types of wattle trees growing on the property. The one out the back did self seed and it is the species I rescued a seedling from that is now in the front garden. The seedlings appeared after the mother tree was cut down, about 6 months later. The other wattle species is the one I'm really interested in because the King Parrots and Little Corellas would eat the seeds when they were available. The King Parrots and Little Corellas never ate from the other wattle tree which is the one I have now growing in my front garden. Does anyone have a special, unconventional way, to germinate wattle seeds successfully?

Thanks spiney and Woko for your encouragement. I've discovered there are plant species that have gone extinct in my area (Tenterfield plateau), and some are very close to being extinct. I found this website that records living specimens of flora in Australia and I'm using that site as a source of reference to ID native flora to my area. Here's the link to that site:

http://bie.ala.org.au/species/urn:lsid:biodiversity.org.au:apni.taxon:113524

No matter where you live in Australia there'll be records on that site for your area. It's useful to everyone. It's made me realise one thing, timber trees were chopped down in the Northern Tablelands until all the trees were basically extinct. I always wondered why there are only Eucalypt, Wattles and the odd Banksia trees in the area. I always wondered why flora diversity is lacking in this area. Now I know why: You take down the biggest trees and the other plants suffer and die, if they're not cut down or bulldozed too. Its a sad, sad tale and depressing to think about all the plant life lost and went extinct in the process just for the need for timber.

I think offering free tree seedlings to people in the area is a good way to go for me. It will get more trees planted and people love free plants. Even I get excited about free seedlings. Just the other day I was at my local nursery (Thrifty Link Hardware store - it's the only place in town where the plants actually survive when I plant them in the ground) and I asked if they had any seedlings of the Camellias that were growing in their nursery wild. I just loved seeing those deep rich pink flowers that the Eastern Spinebills ate from too. They didn't have any seedlings but said I could take some cuttings of it for free. We ended up finding a lot of seedlings popping up and, well, I ended up bringing 7 of the seedlings home and it cost me nothing. I dug them up myself. On Monday I'm going back to get more because I have a home for 6 of the seedlings already and one is going into my garden. I don't care if its an exotic from Japan, it's a plant, and my garden lacks plants. The whole area lacks plants. I hate grass, and the camellia will at least kill off the grass in the area where it will grow. If nothing else camellias produce nectar and drop their flowers and petals and leaves. The camellia will add to the non existance of autumn leaves in my garden - I have to start somewhere to introduce decidious trees. The camellia is that starting point for me. 

I'm not worried about an invasive outbreak of camellias all over town as it isn't happening with that species. Revegetation naturally doesn't happen much, if rarely, in town anyway, except for small pockets of it and it is a very slow process even in the creek itself.

Edit: The local aboriginal name for Tenterfield is "Moombillen" which means "Place of Wild Honey", however, all the plants that are known to produce that type of nectar for the wild bees are gone and basically so are the wild bees too.

If people feel compelled to plant introduced species then it's really important to plant non invasive species, even in places where there's little or no native vegetation. However, I'm just so pleased I've planted indigenous species because so many of my neighbours are doing likewise & now we have wildlife corridors linking revegetated areas to remnant scrub patches. Introduced species would have disrupted those corridors.

I hear ya, Woko. Sometimes I wonder what the heck I am doing planting exotic plants in my garden. The exotics I have planted though are not invasive which you'll be happy about. I'd happily kill an invasive exotic if I learn it is invasive and I bought it unawares of that fact. Sometimes, like in my case, finding indigenous species is really, really hard if not impossible locally. In my case I've resorted to shopping online for indigenous plants. The plants I really want I just can't find or are too expensive for me to buy. I'm now resorting to buying seeds of indigenous plants as I've exhausted my seedling options for plants to grow. I want a semi subtropical rainforest look about my garden and need specific indigenous plants for that look. Can't buy them here so have to look elsewhere. The seeds I planted which are supposed to be annual flowers look suspiciously like weeds to me so I'm going to be ripping them out very soon - all of them - and starting again with something else. Darned weeds!

Would subtropical species survive in Tenterfield's winters? Also, I'm wondering if subtropical species would cost you lots in water & effort in summer. Perhaps I need to be better informed about Tenterfield's climate.

Yes, Woko, they would survive in Tenterfield's winters. It's not the winter they'd have to survive but the autumn, spring and summer. Just with a little bit of planning and thinking about how to block the strong southerly and westerly winds, how to keep the ground cool all year round, and try and get some sort of canopy happening, the rest is actually easy and doable.

Here's a heads up on Tenterfield's climate for ya. Tenterfield is classified as a subtropical highland climate with an altitude of 845 metres above sea level. I haven't been in Tenterfield long enough to state that the climate here goes in cycles. But I can say I've been here since October 1995 and the weather seems to be resorting back to a "rainy" climate again, which last ended in 2001. 

The seasons are like this in the "rainy cycle": Summer: major low level thunderstorms and torrential downpours, cool weather. Ground level clouds roll in and it rains at ground level. No floods occur during this rainy cycle. Autumn: cold and windy with regular rain; frosts; fogs and more rain but it is lighter rain than the summer rain. Winter: cold but a little bit warmer. It still rains though regularly. Around mid July it snows for just one day out of the whole year. Spring: Frosts, fogs and more rain merging back into low level thunderstorms. It rains so frequently in the rainy cycle you can actually set your watch to it. Light intensity levels are low.

During the "dry cycle" it goes like this: Summer - very little rain but most of the rain is from harsh thunderstorms and freaky weather fronts.  Floods are common nearly every summer. Formations of tornados in their beginning phases pass over Tenterfield. Summer is increasingly getting hotter for longer but it will only be for about a month of really hot weather. It then begins to cool down late summer. Autumn: usually dry, warmish, heavy frosts and fogs. Winter: some rain might happen if we're lucky, snow might happen if we're lucky; usually warmer to hotish weather. Around late August to early September it starts getting hotter then gets colder then gets hotter again before summer really kicks in. Spring: thunderstorms usually go around us; can be cold or hot weather. The weather can change at the drop of the hat. It might rain and sometimes it does. The weather is unpredictable. From autumn to late winter the nights are cold (usually to minus 10 degrees celcius) until it starts warming up again around spring. Light intensity levels are high.

Planting subtropical species can work here if all the weather conditions are taken into consideration over a long period of time. The plants have to adapt to it all whether they're delicate species or not. The thing is, Woko, seedlings can survive and adapt to my climate really well if they are not tiny in size. I prefer to keep small seedlings in their containers for longer than normal until I see some plant growth on them, then I put them in the ground. That works out better for the plants as they establish quicker.

Subtropical plants wouldn't cost me lots in water and effort in summer than any other species would. It's simply a matter of keeping the ground cooler than normal by adding more organic matter, plus the occassional watering. I also plant my seedlings deeper than normal and so far my seedlings have not complained or died from it - even my callistemons and wattle tree. 

Ground temperatures can reach to above 50 degrees in summer. That can also happen in spring too so keeping the ground cool, even in winter, is my top priority as it helps the plants survive the frosts and the heat.

Actually, Woko, from what I've read about subtropical rainforests the plants are usually drought tolerant for the most part as they don't get a great deal of rainfall like tropical rainforests do.  I guess growing up in the South Australian climate has given me the upper hand.

Thanks for that, Hyperbirds. I'm learning all the time! And I get the impression that you're learning new strategies that are producing better results.

Does anyone have another method to germinate wattle seeds when the normal soaking of the seed doesn't work?

It may depend how long you soak them for, and the water temperature used.

I have read a couple of different suggestions about soaking acacia seeds - either soak  for several minutes in boiling water, or soak in just boiled water for 4 hours or more.

I tend to have good results when I just take freshly boiled water and pour it over seeds in a glass and leave for 12 - 24 hours. I did this a couple of weeks ago with Acacia fimbriata and Acacia macradenia and they are just coming up now.

Otherwise, nicking the hard coat, as you suggested, is meant to help, so perhaps nicking and then soaking might let the water penetrate and soften the seed a bit more?

I guess there is also potential that the seeds are not fertile if the plant needs to cross-pollinate, but I haven't noticed that being an issue with Acacias myself.

I've had excellent results by bringing a saucepan of water to the boil, waiting a few seconds for the boiling to stop then dumping the Acacia seeds in. The next morning shoots have appeared & the germinating seeds are ready to plant.

Thanks timmo and Woko. Come to think of it the seeds may have been infertile. I don't know why I done this but before I soaked them in boiled water I put them in cold water and they just floated on the surface. Perhaps fertile wattle seed sinks to the bottom when put in cold water first? The darned birds probably ate all the good seed and left me with all the bad ones. Oh well. I'll keep what you both said in mind next time I have wattle seed to germinate.
