How to Grow Genetic Dwarf Cherry

Tree is leafless in winter; buds swell in early spring. Genetic dwarfs begin blooming in mid-spring with abundant white or light pink blossoms.

Prune in late winter while dormant to maintain compact shape and improve light penetration. Apply dormant oil spray if pest pressure was high in previous year. Avoid pruning after growth begins.

Abundant white blossoms cover the canopy. Flowers are attractive to bees and pollinators. Some varieties are self-fertile; others benefit from cross-pollination.

Ensure bee activity and avoid spraying pesticides during bloom. Protect flowers from late frosts if possible using frost cloth. Genetic dwarfs may require hand-thinning if flowering is extremely heavy.

Small green fruits develop where flowers have been pollinated. Fruit gradually enlarges over 6-8 weeks. Heavy crops may require thinning to improve fruit size and prevent branch damage.

Thin fruit to 4-6 inches apart (leaving one fruit per cluster) if fruit set is very heavy. This improves fruit size and quality. Water deeply and regularly. Apply mulch to conserve moisture. Monitor for splitting due to excess rain.

Fruit changes from green to red to deep burgundy or black depending on variety. Flavor develops fully when fully colored. Fruit becomes soft and sweet.

Water consistently to prevent fruit cracking from rain after dry periods. Do not pick too early; fruit does not continue ripening after harvest. Watch for bird damage; use netting if necessary.

After harvest, tree enters late summer growth phase and begins preparing for dormancy. Leaves may show stress if tree is very heavy-cropped.

Provide deep watering through late summer into fall. Reduce nitrogen fertilizer to avoid stimulating new growth that may be frost-damaged. Sanitize pruning tools after harvest to prevent disease spread.
