Establishment (Year 1)
12 monthsYoung tree focuses on root development and framework growth with limited branching and leaf production.
Water consistently, stake for support in windy locations, remove flower buds first year to encourage tree development, apply mulch around base.
Juvenile Growth (Years 2-3)
24 monthsTree develops main scaffold branches and begins to fill out its form; occasional flowering may occur.
Prune to establish open center or modified leader form, thin congested growth, continue regular watering and mulching, allow light fruiting to begin in year 3.
Flowering
2-3 weeks in springWhite flowers with pink tinges bloom in clusters along branches in early spring before leaf emergence.
Protect blossoms from late frosts with frost cloth if necessary, ensure pollinator access (damson is self-fertile but benefits from pollinators), do not fertilize heavily to avoid excessive vegetative growth.
Fruiting & Development
8-10 weeksSmall green fruit develops and gradually enlarges; fruit remains green until late summer when it transitions to dark purple.
Thin fruit to 2-3 inches apart for larger individual plums, maintain consistent watering, apply balanced fertilizer mid-summer, monitor for pests and diseases.
Harvest & Dormancy
2-3 months harvest period; dormancy through winterFruit reaches full dark purple color in late August to September; leaves yellow and drop in fall, tree enters winter dormancy.
Harvest when fruit yields slightly to pressure, do not pick too early or flavor will be tart, prune after harvest to remove diseased wood and shape tree, apply dormant oil spray in late winter.

Common Pests
-
Apply kaolin clay spray before flowering, remove and dispose of infested fruit, use insecticidal soap in early summer, maintain tree vigor
-
Apply neem oil or spinosad in late spring, use pheromone traps to monitor population, harvest promptly, remove mummified fruit from tree and ground
-
Apply organic insecticides at petal fall stage, thin damaged fruit, use sticky traps, encourage parasitic wasps
-
Prune out infected branches, improve air circulation through pruning, remove mummified fruit, apply sulfur fungicide in wet conditions, avoid overhead watering
-
Prune out black knots during dormancy well below the knot, destroy prunings, maintain tree health, apply dormant oil in winter

Harvest Tips
Harvest in late August to September when fruit is fully dark purple and yields slightly to gentle pressure. Pick fruit directly from branches or allow to drop and collect daily. The fruit ripens over several weeks, allowing multiple harvests. Bradley's King damson is best used cooked (not fresh eating) for jams, jellies, wines, gin, or compotes. Fruit stores well in refrigeration for 3-4 weeks and freezes excellently for later processing.
Fun Facts
- 🌱 Bradley's King Damson is self-fertile, meaning a single tree will produce fruit without requiring a cross-pollinator, though pollinator presence increases yields.
- 🌱 Damson plums are named after the city of Damascus and have been cultivated for over 2,000 years, with documented use in European orchards since medieval times.
- 🌱 The fruit has a distinctive, tart flavor when raw but transforms into complex, rich sweetness when cooked, making it far superior for preserves than fresh eating compared to dessert plum varieties.
