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

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!
