Diseases of Plum Trees
Harvesting
and Storing Plums
|
| Plum trees will begin to produce fruit at four or five years old. Like most fruit, leave the plums on the tree until they are ripe and ready to eat. Ripe plums will be produced over a month or so and it is best to pick a few but often over this time. Any diseased fruit should be removed immediately because they will only attract diseases and wasps. |
Ripe plums keep for only a few days and are best stored in the fridge. If you want to keep plums for longer, pick them when they are slightly under-ripe, placing them in a paper-lined box in a cool dark place.
