Fruit splitting
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.
Described view
Three apples on one surface with a scale reference: one split cleanly along a fresh crack with pale unblemished flesh showing, one carrying the corky olive-brown scab lesions that crack the skin as the fruit expands, and one with the concentric buff pustule rings of brown rot spreading from a wound
What brings it on
A sudden change in water availability while fruit is ripening. Cherries are the classic case: heavy rain in the last fortnight before picking can split most of a crop in a day.

Preventing it
Ordered by how much difference each measure actually makes, not by how often it is repeated.
- Water evenly through the season, and mulch to even out what the roots experience between waterings. Most splitting traces back to a dry period the grower did not correct rather than to the rain that finished it.

- Where a cherry is trained against a wall, a temporary cover over the ripening crop keeps the rain off during the fortnight that matters.

Dealing with it once it is there
- Use split fruit immediately — it is perfectly good, and it will not keep. Remove any that has started to rot so brown rot does not spread through the crop.

What it affects
Signs that lead here
Each of these lists the other things that produce the same sign, and how to tell them apart.
On sprays and treatments
GrowingHQ does not tell anyone what to apply, at what rate, or how often. Pesticide approvals differ by country, change without notice, and the product label is legally binding — it is also the document you are holding. What is described here is cultural and physical control, which is what a home grower can act on without a label in front of them.

Where this is one of several causes that look alike on a particular plant, GrowingHQ publishes the differential rather than the general answer.
