Specifically, I have a mume on which I wish to air layer a branch. Leaves on the branch have opened, but haven't hardened off yet. Is this a good time to air layer?
Generally, on deciduous trees, what is best time to air layer? Before tree breaks dormancy? As buds begin to swell? As buds begin to open? As young leaves open? After leaves have hardened off?
Thanks for any information.
