Sweet Cherry · Prunus avium

Why are there spots on my sweet cherry tree leaves?

Spots on your sweet cherry leaves are often a sign of fungal infection, like shot hole disease or cherry leaf spot. Brown rot can strike at the same time, but it mainly attacks blossoms and fruit. Check the underside of the leaves and the fruit for signs of fuzzy growth or lesions.

Check these first

  1. Inspect the fruit for fuzzy gray or brown mold.
  2. Look for small holes in the leaves.
  3. Check if the blossoms turned brown and shriveled.

Likely causes

  1. Brown Rot

    Most likely

    How to tell: You will see blossoms wilting and turning brown, followed by fruit decaying while still on the tree.

    What to do: Remove and destroy all infected fruit and blossoms immediately. Apply a copper based fungicide during the dormant season or early spring to prevent spores from spreading.

  2. Shot Hole Disease

    Possible

    How to tell: Small red spots appear on leaves that eventually fall out, leaving behind a hole that looks like a bullet hole.

    What to do: Prune away infected branches to improve airflow through the canopy. Keep the area under the tree clean of fallen leaves to reduce fungal buildup.

When to worry

If the spots are spreading rapidly to the fruit, you risk losing your entire harvest. A few spots on older leaves late in the season are usually harmless.

Stopping it coming back

Prune your tree annually to keep the center open for sunlight and air circulation. Always rake up and dispose of fallen leaves and fruit in the autumn.

Questions people ask

Can I eat cherries that have spots?
If the spot is just on the skin and the fruit is firm, you can cut it away. If the fruit is soft or has mold, it is best to discard it.
Will these spots kill my tree?
Most fungal spots are cosmetic or affect the fruit, but severe cases of brown rot can weaken the tree over time. Proper pruning usually keeps the tree healthy.
