Cherry: fruit splitting or cracking

2 causes GrowingHQ holds specifically for cherry, what separates them, and what is safe to do before you are sure.

What you are looking at

Fruit opening along a seam or across the skin, usually close to ripening. What matters is not the split but what is inside it: a clean fresh crack after rain is a water event and the fruit is still worth picking, while a split that has gone brown, soft or furry is a rot that will spread to the fruit touching it.

    Fruit splitting open on the plant, usually after rain following a dry spell. Nothing is attacking it: the inside has taken up water faster than the skin can grow, and the skin gives way. The split then lets brown rot in, which is where the real loss comes from.

    Points towards it

    • · rain on ripening fruit is the mechanism, and it needs rain
    • · a downpour reaches the whole tree at once

    Argues against it

    • · fruit kept dry through ripening cannot take up water through its skin, which is the entire mechanism — this rules it out entirely.

    Check this next

    Check how close the fruit was to ripe and what the weather did. Cherries split in the last week or two before picking and only then — water is absorbed through the skin faster than the flesh can expand, so the skin gives. Fruit still hard and green does not split whatever falls on it.

    What to do now

    Pick the split fruit promptly and use it, and pick the sound fruit as soon as it is ready rather than leaving it for the last few days of sweetness. Nothing sprayed on the tree prevents this; the only real preventions are a cultivar less prone to it and, on a trained tree, a temporary cover through the ripening fortnight.

  2. Brown rot

    • Royal Horticultural Society: Brown rot

    Checked 2026-08-13

    Fruit turning brown and soft with concentric rings of buff pustules, often while still hanging. Affected fruit shrivels into a hard 'mummy' that stays on the tree over winter and infects next year's crop from where it hangs.

    Points towards it

    • · it spreads between fruit that are touching, so it appears in clusters
    • · the buff pustules form in rings on the rotting surface

    Argues against it

    • · damage spread evenly over the whole tree in one night is weather, not a fungus

    Check this next

    Look at what the split fruit is touching. Brown rot moves from fruit to fruit by contact, so it appears in clusters with a mummified one at the centre — a weather split is scattered wherever the fruit happened to be ripest, and the flesh at the edge of the crack stays firm and pale.

    What to do now

    Remove every rotting and mummified fruit, including the shrivelled ones still hanging in winter, and dispose of them away from the tree. Those mummies are where the fungus overwinters, so clearing them does more than anything else available to a home grower — and thinning the crop so fruit does not touch removes the route it spreads by.

Narrow it down

This page lists everything at once, which is the right shape for reading and the wrong shape for deciding. The interactive tool asks one question at a time, starting with whichever would separate these causes fastest, and stops as soon as further answers would not help.

Work through it for your cherry

Opens with the plant and the symptom already set. Nothing you answer is stored or sent anywhere — the answers live in the address bar and nowhere else.

What this does not cover

These are the causes GrowingHQ holds rules for on cherry — not every cause there is. Where several problems look alike, the honest answer is often that they cannot be told apart by eye, and a page that named one would be guessing. If none of the above fits, the general fruit splitting or cracking page lists causes across all plants, and the Cherry profile lists the problems it is prone to.
