Dormancy (Winter)
December-FebruaryTree is leafless with bare branches; buds are visible along the stems
Prune during late winter while dormant to shape tree and remove dead/diseased wood. Apply dormant oil spray in late winter to control overwintering pests. No watering needed unless conditions are extremely dry.
Bud Break & Spring Growth
March-AprilPink to white blossoms emerge; leaves begin to unfurl. Flowers appear before or with new foliage.
Do not apply fungicides during bloom. Protect from late frosts which can damage flower buds. Ensure adequate water as growth accelerates. Monitor for early pest activity.
Flowering & Pollination
2-3 weeks in springTree is covered in pale pink to white flowers in clusters; bees actively visiting blossoms
Plum Delight is self-fertile but benefits from cross-pollination. Ensure bee activity by avoiding pesticide sprays. Thin flowers by hand if excessive fruit set is anticipated to prevent branch breakage.
Fruit Development & Growth
May-JulyTiny green plums form and rapidly increase in size; tree is fully leafed out with vigorous growth
Thin fruit to 4-6 inches apart to ensure larger, sweeter plums and reduce branch stress. Apply consistent watering (1-1.5 inches weekly). Feed with balanced or slightly potassium-rich fertilizer. Monitor for pests and diseases.
Maturation & Harvest
Late July-September (varies by zone)Plums darken to deep purple, become soft to gentle pressure, and develop full sweetness
Stop major pruning to allow energy to go to fruit. Maintain consistent watering but reduce if fruit is ripe. Begin harvesting when plums yield slightly to thumb pressure and have fragrance. Pick carefully to avoid bruising.

-
Thin fruit to reduce attractive surface area; apply spinosad every 10-14 days during flight season; wrap individual fruit in paper bags
-
Prune off diseased branches 12 inches below knot; improve air circulation; apply copper fungicide in early spring and fall

Remove mummified fruit; thin tree for air circulation; apply sulfur or copper fungicide during bloom and fruit stage; avoid overhead watering

Harvest Tips
Pick plums when they are deep purple and yield slightly to gentle thumb pressure. They should have a sweet fragrance. Harvest in the morning for best flavor. Plums continue to ripen slightly after picking if left at room temperature. For best flavor, eat within a few days of harvest. Stagger picking over several weeks as plums ripen sequentially.
Fun Facts
- 🌱 Plum Delight is self-fertile, meaning a single tree can produce fruit without a separate pollinator tree, making it perfect for small spaces and urban gardens.
- 🌱 Plums have been cultivated for over 2,000 years, with evidence of cultivation dating back to ancient China and Persia, making them one of humanity's oldest fruit crops.
- 🌱 The deeper the purple color of a plum at harvest, the higher the antioxidant content, particularly anthocyanins, which give the fruit its dark hue and health benefits.
