Planting & Establishment
First 2 yearsYoung tree with bare branches and developing root system
Plant in spring or fall. Stake if necessary for windy sites. Water deeply 2-3 times weekly. Apply 2-3 inches of mulch around base, keeping away from trunk.
Juvenile Growth
Years 2-4Tree developing branch structure and increasing in height and width
Remove competing leaders. Prune only to establish strong framework. Reduce watering frequency as roots establish. Monitor for pests/disease.
Flowering
Late April to early May, 2-3 weeksDense clusters of deep pink to red flowers covering branches in mid-spring
Flowers appear on second-year wood. Do not fertilize excessively (reduces flowering). Avoid pruning during bloom period. Light spring pruning after flowering is acceptable.
Fruiting
August through JanuarySmall (0.5-0.75 inch) bright red crabapples develop and mature throughout fall
Fruits persist into winter if not eaten by birds/wildlife. No thinning necessary. Provide consistent water during hot, dry spells to support fruit development.
Dormancy
January through MarchTree leafless with persistent red fruit and architectural branching visible
Minimal care needed. Prune only to remove dead, diseased, or crossing branches during late dormancy (February-March). Enjoy winter interest and wildlife food.

Fun Facts
- 🌱 Robinson Crabapple was selected and named by the University of Minnesota, reflecting its cold hardiness and disease resistance bred for northern climates.
- 🌱 The tree's persistent fruit (often remaining until December or later) is valued by birds and wildlife; cedar waxwings particularly favor the abundant berries.
- 🌱 All true crabapples can be eaten and used for jelly—the distinction from ornamental apples is primarily size rather than flavor or safety.
