stratification

Hi there! About a month ago I came back from a visit to Denver with 5 pine cones from a Colorado Blue Spruce in my family's yard. I understand there's roughly a 1/1000 chance of getting the characteristic blue coloring of the parent tree, but I'm still interested in trying to stratify and...

Hello I currently live in St. Louis Missouri in USA. Six months into doing bonsai‘s and thus far I have been unable to germinate any Judas. I am roughly 1 for 100 in the redwood area. (Still alive but accidentally burn the starting leaf’s, growth is extremely slow but fully recovered from...

Hello I had tried the Mugo pine and Silverbirch stratification and germination before unfortunately with 0% success I was wondering if anyone has had any success and getting these little buggers to germinate. All info would be much appreciated thank you very much

I’ve tried germinating acacia and Sakura seeds three times now from purchases on Amazon I now purchased more viable seeds from individuals on Etsy. I was just looking for other people who have successfully germinated these and to see if their method was different than mine thank you.

Hi guys, new here to Bonsai nut. Ive got a few plants I've grown from seed that seem to be flourishing quite well, maybe cause of the fantastic Summer we've all enjoyed. I bought most of my seeds that don't require stratification but I somehow ended up with some Chinese Juniper seeds (late...

Hello everyone I bought last week some Pinus Thunbergii (Japanese black pine) seeds. On the instructions says that I have to do a cold stratification of 2 months and plant them in spring. I assume it is a little bit too early to begin with the stratification now.... so what should I do with the...

As many of my threads have indicated, I am starting tons of Seeds this winter. Hopefully as you know, all seeds can benefit from cold stratification. Not necessary for some but germination rates do increase. So I have been reading M. Dirr's propagation manual (absolute MUST have for your book...
