Plums, Pluots and Prunes
Plum trees can be grown almost anywhere in California. They are easy to grow. Most plums require cross pollination. There are two basic kinds of plums: Japanese (Prunus salicina) and European (Prunus domestica). Both require 140-170 days to mature the crop. Most Japanese plums bloom earlier and mature earlier and they require less chilling than the European plums.

PLUMCOTS, PLUMLIKE, APRIUMS
A plumcot is a 50-50 cross between a plum and an apricot.
A plumlike is 75-plum and 25 apricot cross.
A Aprium is a 75-apricot 25 plum cross.
For good pollination plumcots amd plumlikes should be planted with other plumcots or plum varieties nearby. Apriums should be planted with other aprium varieties or apricots nearby.
Plumcots and plumlikes use plum rootstock. Apriums use apricot rootstock.
