Plum 'Santa Rosa'

Prunus salicina 'Santa Rosa'

1/4

Plums are medium sized deciduous trees. For best results always ask a local nursery for advice on choosing the best variety and rootstock combination for your garden. Burbank and Shiro are used as cross pollinators for Santa Rosa. Santa Rosa plums are red with orange to red flesh and need at least 400 chill units to produce a good crop.

Harvesting

Fruit have the best flavor when left to ripen on the tree. You can tell when plums are ripe by applying gentle pressure with your fingers. If the skin of the fruit feels soft, then it is ready to be picked. Plums should come off the tree easily. Commercial farmers will test for sugar content and will only start to harvest if the plum have reached a high enough sugar level. They do not continue to ripen after harvesting. Plums are harvested at the end of December.
