Hi Grant,

I'm assuming you were living in Canberra when sewing your seeds? Lets face it, Canberra in winter is cold enough to get enough chill hours to break dormancy for most plants. Probably anywhere inland along the ranges that gets frosts would be.

However, cold stratifying in a fridge is a standard technique if your environment is not cold enough to break dormancy.

Some one asked about zelcova, Never tried them from seed, only grown from cuttings. But yes, I think it should work.

My nursery used to be at Yerrinbool, almost at Mittagong but lower in altitude; no colder than western Sydney; in fact I used to find where Kingston Wang (Vineyard) lives much colder..

Do it the natural way, better results.

I agree wholeheartedly Grant. and maybe if it is too warm for seed to germinate maybe its too warm for the trees to do well too????
Surely if the trees grow ok in the area there will be some with seed you can collect???

Thoglette I can supply fresh seed (Are we allowed to send seed to WA?)- picked straight off the trees- of trident maple and Japanese maple most years. Currently have thousands of trident seedlings germinating all over the garden beds and in the pots from the seed that fell during winter. still seed hanging on the tridents but i have not checked the Japanese maples recently.

Hi Grant

The maple tree I planted in my mums backyard and collect seed from is in Chatswood. Plenty of seeds form on the tree and then fall off, but very very few ever germinate on their own.

Maybe they just need a little cold to get them going. As I posted earlier, I cold stratify to get a more even emergence, this helps with seedling cuttings as they are all very similar in size.

Thanks - the answer is : perhaps, it depends. It depends on the species and the year you ask the question (the regulations change regularly).

Ah, I recall. The problem is not the seed, it is guaranteeing that it is "free of organisms that are declared pests". Last time I looked the bar appeared too high for amateurs. All the rules have changed this year so I need to look again

When I lived in down town Yagoona I collected Japanese maple from Epping, Trident maple from Carlingford, and imported JB pine from Japan.

All germinated well with no stratification .

Brian at Imperial bonsai stratified his JB pine seed and got nothing. I advised him not to stratify. Terrey Hills is cold enough.
