Season-by-season care

Spring

Prune if needed Early spring

Prune to shape in early spring before bloom. Light pruning only -- heavy cutting reduces berry production.

Verify male pollinator nearby Spring

Winterberry requires a male plant within 40 feet to produce berries. One male pollinates up to 6 females.

Summer

Maintain consistent moisture Throughout summer

Winterberry is naturally a wetland plant and prefers consistently moist soil.

Fall

Enjoy berry display After leaf drop

Brilliant red berries persist after leaf drop creating a stunning winter display. Do not prune.

Ecological value

Berries are a critical winter food source for cedar waxwings, bluebirds, robins, and mockingbirds. Plants provide shelter for overwintering birds.

Never miss a winterberry holly care window again
