Lapins thrives in the ground in full sun across USDA zones 5-9. Give it room to reach its mature 15-20 ft. height and 10-15 ft. spread, in a spot with deep, well-draining soil — sweet cherries dislike wet feet more than almost anything.
Planting
- Choose a site in full sun (at least 6-8 hours daily) with good air movement and soil that drains freely; avoid low pockets where water collects.
- Dig a hole twice as wide as the root ball but no deeper, loosening the sides so young roots can push out.
- Set the tree so the graft union (the slight bulge low on the trunk) stays a few inches above the soil line — never bury it.
- Backfill with the native soil, firm it gently to remove air pockets, and water in thoroughly to settle the roots.
- Spread 2-3 inches of mulch over the root zone to hold moisture, keeping it pulled back several inches from the trunk to prevent rot.
Care & maintenance
- Water. Keep the soil evenly moist the first two years while roots establish; once mature, water deeply during dry spells, easing off as fruit ripens to protect against splitting.
- Feed. Apply a balanced fruit-tree fertilizer in early spring as growth begins; avoid heavy late-season nitrogen, which pushes soft growth that won't harden before winter.
- Light & temperature. Full sun yields the sweetest fruit. Lapins is hardy to zone 5 and needs a sufficient winter chill to fruit well, so it is best suited to climates with a genuine cold season.
- Prune. Prune in late summer after harvest (not in wet winter weather) to reduce disease risk; open the canopy for light and air, and remove dead, crossing, or crowded wood.
- Pollinate. Lapins is self-fertile, so one tree will set fruit on its own. A nearby compatible sweet cherry can still boost yields, but it isn't required.
- Pests & disease. Watch for brown rot, bacterial canker, aphids, and cherry fruit fly; good airflow, clean fallen fruit, and prompt pruning of cankered wood keep most problems in check. Netting helps protect ripening fruit from birds.
- Harvest. Cherries ripen in May through June. Pick when fully colored and sweet, ideally with the stems attached, and taste-test before a big harvest since flavor peaks at full ripeness.
