Establishment
First 1-2 yearsYoung tree developing a strong root system with upright central leader and initial branching
Water deeply and regularly; stake if necessary to support upright growth initially; protect from strong winds; mulch around base with 3-4 inches of organic material
Branch Development
Years 2-4Weeping branches begin to lengthen and droop gracefully; canopy fills in with heart-shaped leaves
Prune only to remove dead or crossing branches; allow natural weeping form to develop; continue consistent watering; reduce staking as tree strengthens
Flowering & Fruiting
Late spring through summerTiny greenish flowers appear in spring, followed by elongated berry clusters (white, red, or dark purple depending on variety); berries mature to soft, juicy fruits
No special care needed for flowering; thin out crowded branches if berry production is desired; birds and wildlife will aid in pollination; berries attract birds and wildlife
Dormancy
Late fall through early springLeaves turn golden-yellow then drop in fall; branches remain visibly dramatic throughout winter
Remove any dead or damaged branches during dormancy; prune to maintain weeping form; no watering needed in cold regions; mulch base for winter protection in zone 4b
Mature Tree
Year 5 onwardFully formed weeping canopy with strong branching structure; consistent fruit production and ornamental display
Minimal pruning needed; remove any upright shoots that disrupt weeping form; monitor for pests and diseases; maintain mulch layer; fertilize lightly in early spring if needed

Harvest Tips
Berries ripen in early to mid-summer (June-July depending on region). Pick when fully ripe (soft and dark colored) by gently brushing branches to drop fruit onto a cloth. Eat fresh immediately, or freeze for later use in jams and smoothies. Wear gloves or protective clothing as ripe berries stain easily.
