I just love these early flowering trees in the spring. First sign of life in the woods. Had to have one this spring but had to buy a seedling. Been on the lookout for a collectable one. I didn't know they had a fall surprise for me. Love to see any members Redbud if you have one. Or even some...
They definitely are sensitive to root reduction, but not impossible to transplant. I know two members of my club who have successfully collected wild, established redbuds. One of them is 4-5 years post-collection.
Being a legume, which are known to have symbiotic relationships with bacteria, it's possible that they may benefit from leaving some of the field soil with the rootball upon collection. Just speculating there...no data to back it up.
Hi — late to the party here but I have a few tips I learned from experimenting with a fecund redbud in my yard that loves to produce volunteers…
So far the best trick I’ve discovered is to place 5 gal buckets with 1/4” holes drilled in the bottom and sides (or any deep pot with drainage holes), and a few inches of regular ol’ potting mix at the bottom around the base and drip line of the tree, catching the seed pods as they would fall naturally.
As the saplings start to mature you can raise the soil level little by little. This encourages the rapid development one would achieve under natural circumstances while discouraging the tree from forming that massive taproot which makes this species difficult to collect and recover. Hope this helps anyone looking to collect and experiment with this species as there is not much info out there. Good luck!!
