Establishment
First 1-2 yearsYoung plants develop a low, spreading mat of wiry vines with small evergreen leaves.
Plant in early spring or fall. Keep soil consistently moist. Mulch lightly with sand. Do not allow soil to dry out. Avoid fertilizer the first year.
Vegetative Growth
Years 2-3Vines spread horizontally, rooting at nodes and forming a dense mat. Dark green narrow leaves on upright flowering shoots.
Allow vines to spread and fill the planting area. Maintain consistent moisture. Apply thin layer of sand annually in spring. Manage weeds carefully. Avoid high nitrogen fertilizers.
Flowering
May-JuneSmall pale pink or white bell-shaped flowers appear on upright shoots in late spring and early summer.
Flowers are self-fertile but benefit from pollinator activity. Ensure adequate light. Keep moisture consistent. Do not fertilize during flowering.
Fruit Development
June-SeptemberGreen berries form and gradually enlarge to full size by mid-summer, then slowly turn deep red.
Maintain consistent watering during this critical period. Provide adequate sun exposure. Monitor for pests and diseases. Light summer irrigation flooding can improve yields.
Harvest
September-NovemberFully ripe berries are deep red and firm. Some berries may remain on vines after first frost, which actually improves flavor.
Harvest when berries are fully colored and firm. Wet harvest (flooding and mechanical reaping) is common commercially. Hand-pick for fresh market. Store at 36-40°F.

Harvest Tips
Wentworth berries are typically harvested in September through November when fully red and firm. The Wentworth variety is particularly suited to wet-harvesting, where the bog is flooded and a mechanical reaper separates berries from vines; berries float and are collected. For home gardens, hand-harvest ripe berries by gently twisting or cutting from the vine. Properly stored cranberries will keep for several months at 36-40°F in high humidity.
