i got one not too long cutting from UCD this spring. i cut that in half. this is the top half that survived. for whatever reason, lot of my cuttings died this yr in 1 gal pot. more than likely due to me trying to flush out the lime with ton of water.
the dead on had red stem and red leaves. they try to stay alive as much as possible. but one morning i noticed the leaf and bud dried up pretty good and the cutting itself starting to dry up.
i notice on lot of my trees out back, the leaves, stems, and bud turning red when the temp cools down.
