Q

I have an braeburn apple tree that we got from a local nursery last fall. the leaves were slightly curled after we planted it and i thought that it was just transplant shock but this spring it has not cleared up. All the leaves are curled up on the edges.

Answer(s)

A

I have been asked to respond to your question about your apple tree.
 
You are right, transplant shock would have been the most likely explanation for what is going on. With our mild, wet weather this spring your tree should not be so stressed, though. Here are some things to consider. If you could send us the answers to these questions, it would be helpful. Also, If you can attach a few pictures, that would also help in diagnosing your tree problem.
 
Is it possible that the rootball or root system was jostled or damaged during transplanting? If so, that could be the source of the problem.
 
What is your soil like? How is the drainage? When you planted the tree, did you add any compost or other amendment to the soil that you put back into the planting hole?
 
How often did you water the tree last year, for how long and what method did you use? Is your tree in the lawn where it is getting watered by the lawn sprinklers? Have you been watering the tree this year?
 
You describe the leaves as curling up. Were they normal-looking when they first emerged or have they been curled since the very beginning of the year? Are they rolling lengthwise or are they becoming cup-shaped? Has your tree been exposed to any herbicides last year or this year?
 
Once we have this information, we will be able to better help you. You are also welcome to come in with some small sample twigs from your tree, if you prefer. We are located at 100 East Center Street in Provo. We are in the County Administration building in L600 in the basement. We are open M-F from 8-5.
