Honey Suckle Which Had Yellow Leaves Now Has Green Leaves

Question From: P. Hooper - Hersham, England, United Kingdom
Q: My Gleditsia had yellow leaves when I bought it, two years ago, but it is now a uniform green. Can it be encouraged to return to its original colour.

A: I am not familiar with this plant, but my guess is it was selection or hybrid that has reverted. I'd take samples to an independent nursery that grows and sells these plants for an accurate assessment. Best And Happy Yardening, Nancy
