Natural fruit drop
A tree or plant shedding some of the fruit it has set, usually a few weeks after flowering. It is self-thinning rather than a failure: far more flowers are pollinated than the plant can carry to maturity, and the fruit that fall are the ones it has decided against. Apples do it so reliably in early summer that the event has a name.
What brings it on
Normal after a heavy set, and heavier after a stressful spell — drought or a cold snap while the fruitlets are sizing makes the tree shed more of them.

Preventing it
Ordered by how much difference each measure actually makes, not by how often it is repeated.
- Keep the plant evenly watered while the fruit is sizing. That reduces how much is shed; it does not stop the process, and it should not.

Dealing with it once it is there
- Do nothing. A tree shedding some fruitlets in early summer while the rest stay firm and green is behaving normally, and thinning the remainder by hand often improves the size of what is left.

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