The honey locusts are sprouting like crazy while I only have a few persimmon sprouts. Apples have even sprouted!
After setting up my breeding tent, I have removed the dome cover from the seed trays and places the sprouts under intense light.
Once they grow enough to develop their first true leaves, they will be repotted into a deeper container. At this time I will also put a fan on them to simulate wind. Wind is what gives trees strength in their trunk development so this is a crucial step.
