Q.Robinia Frisia Health Problems
small robinia, 5 years old, has been perfect health until I cut back a few overly long branches in early spring, leaveflets on new shoots have turned brown and crisp at the ends while the resto of the small tree looks fit and healthy. I’ve had very long hot spring and summer days and may not have watered as I should, Its on clay soil in full sun. Hoping its not the frisia die back Any suggestions please.
