Check these first

  1. Examine the fruit for tiny holes or soft patches.
  2. Look at the tips of new branches for clusters of insects.
  3. Check for sticky residue on the leaves.

Likely causes

  1. Cherry Fruit Fly

    Most likely

    How to tell: You might notice tiny pinprick holes on the fruit surface. Inside, the fruit will be soft and contain small white larvae.

    What to do: Hang yellow sticky traps in the tree canopy in late spring to catch adults. Use an organic spinosad spray once the fruit begins to change color to protect the crop.

  2. Aphids

    Possible

    How to tell: Leaves will look curled or sticky with a shiny substance called honeydew. Look for clusters of tiny green or black bugs on new growth.

    What to do: Spray the leaves with a strong stream of water to knock them off. If the infestation is heavy, apply neem oil or insecticidal soap.

When to worry

If you find larvae inside your cherries, the fruit is not edible. Aphids are usually a minor nuisance unless they are causing severe leaf curling.

Stopping it coming back

Keep the ground under your tree clear of fallen fruit to stop the life cycle of fruit flies. Encourage beneficial insects like ladybugs to visit your garden.

Questions people ask

How do I know if my cherries have worms?
If you see small holes on the skin, the fruit is likely infested. You can also float the cherries in salt water for 30 minutes to see if any larvae emerge.
Are aphids harmful to the tree?
They can stunt new growth and spread viruses, but they rarely kill a mature cherry tree. Treat them early to keep the tree vigorous.
