Water regularly, mulch 2-3 inches around base, avoid pruning first year to allow energy for root development, provide shelter from harsh winds if needed
Vegetative Growth
Years 2-4Rapid branch and leaf development; plant fills out with characteristic three-lobed foliage
Continue consistent watering, light pruning to shape if desired, fertilize lightly in early spring with balanced fertilizer or compost
Flowering
3-4 weeks in late springWhite lacy flower clusters (cymes) appear in late spring (May-June), covering branch tips with showy blooms
Ensure adequate moisture and sunlight for full flowering, avoid pruning immediately before flowering, do not deadhead flowers if berries are desired
Fruiting & Ripening
August-DecemberSmall red berries develop from fertilized flowers, ripening from August through fall to bright red color; berries persist on branches into winter
Maintain consistent moisture during fruit development, refrain from pruning or harvesting branches with developing berries, leave berries for wildlife or harvest for jams if desired

Harvest Tips
Berries are fully ripe and most flavorful in late September through October after first frosts. Harvest berries by cutting branches with fruit clusters; they can be used fresh, frozen, or processed into jam, jelly, or syrup. Leave some berries on plant for wildlife. Berries can remain on plant into winter if not harvested.
Fun Facts
- 🌱 American Cranberry Bush is the state shrub of Quebec and is native to northern temperate forests across North America, where it has been used by Indigenous peoples for centuries for both food and medicine.
- 🌱 The shrub's berries can remain on branches well into winter and actually improve in flavor after exposure to frost, which breaks down cellular walls and increases sugar concentration.
- 🌱 Despite its common name, American Cranberry Bush is not closely related to culinary cranberries (Vaccinium macrocarpon) but is a viburnum; it's sometimes called highbush cranberry or mooseberry in different regions.
