I'm throwing this thought process out there to see if anyone else has
1) had the issue I have, and
2) figured out a solution.
The issue is that I have 3 specific seedlings that have been blooming primarily in the fall (like 95% of the time) for the past 3 years and I want to use them to breed in the spring. Based on their parentage I believe they are all rebloomers, but because they first bloomed in the fall, and they bloom prolifically, they never have enough unbloomed rhizomes in the spring to bloom.
Here's my thought... They're dormant right now so I'm wondering if I can did them and bare-root them for some amount of time to stunt them before replanting them (in maybe late September? I'm in zone 6b). I think that if I can plant them just before the first bad weather - long enough that they'll root and make it through the winter - I may be able to reset their "clock." Any thoughts or experiene?
