Botanical Overview
Capulin Cherry (Prunus salicifolia), a member of the Rose family and the Prunus

sell a Sweet Cherry (Prunus avium) cultivar named 'Capulin'.
That is not the species discussed here.

Cultivation and Uses
USDA hardiness zones:
9-10. This tree withstands 19°F (-7.2°C) with only small branch damage.
Chill hours:
None, unusual for a Prunus species.
Heat tolerant:
Extra water is needed above 90°F (32°C).
Drought tolerant:
No.
Sun:
Full sun.
Planting:
Locate this tree in well draining soil where it will receive full sun above 4000' (1220m)
elevation. It may need afternoon shade at lower elevations.
It will do better near a pond or other water source if it is not in a high rainfall area.
This tree does not perform well in a container.
Soil:
Well drained, low organic content, pH 5.6-6.5 (acidic to slightly acidic).
This tree is not salt tolerant.
Fertilize:
Apply organic fertilizer late winter.
Water after becoming established:
Deep water weekly when fruiting, every 3-4 weeks
when not fruiting. Abundant water improves the flavor of the fruit.
Mulch:
Spread organic mulch inside the drip line and 8" (21cm) away from the trunk to minimize
moisture evaporation and heat stress.
First Year Care:
Deep water to develop a strong root system. Protect from frost. Stake carefully to prevent
damage from strong winds.
Prune:
This tree can be pruned into a fruiting hedge. Remove damaged branches after the danger of
freezes is past.
Litter:
Low except unharvested fruit and seasonal leaf changeover.
Propagation:
Softwood cuttings grown in an enclosure with higher humidity. Cuttings of desirable varieties
grafted onto seedling rootstock. Seed, cold stratified for 3 months. Seed does not breed true
and the seedling may produce poor quality fruit.
Pests:
This tree is less prone to disease than other stone fruit trees, especially sweet cherry.
Uses:
Ornamental, edible fruit.
