The Q&A Archives: Leaf curl

Question: The leaves on the pear tree are curling especially the new growth. What is the cause?

Answer: Patricia,

That may be due to some type of insect feeding on the young leaves. Aphids are among the insects that can cause leaves to curl. Another possibility is damage from a broadleaf weed killer. Using a weed and feed fertililzer around the plants is one way such weed killer damage can occur. Another is using a sprayer to spray the pear that had previously been used for spraying weeds.

I suggest you take some of the leaves (cut off the end of a shoot with leaves attached) to your parish Extension Office to see if they can look it over and make a more positive diagnosis. Put the sample in a plastic bag so no culprits escape.

Thanks for the question. Please stop in again soon!
