Apple tree needs some support #880418

Asked August 06, 2024, 2:45 PM EDT

Hi, I live in Bend area and have an apple tree that has something like "rust" on the branches and some brown spots on the leaves. What can I do/try to help it be more healthy?

Hi Heather:

This looks like it could be apple scab. To limit it's occurrence, use proper pruning techniques to open tree canopy and improve air circulation. Remove and burn diseased branches and fallen leaves. Also remove from the tree any mummified fruit.  We had a wet spring, which probably did not help the situation.  The link below provides more information on Apple Scab and how you can prevent it's occupancy in future seasons.
