Gardening guidance focuses on protecting various berry plants from winter damage through specific maintenance and insulation steps.

For strawberry plants, recommended care includes renovation, fertilization, watering, and mulching. To prevent fatal damage to plant crowns from temperatures below 15 degrees Fahrenheit, gardeners are advised to apply a three-to-five-inch layer of straw or pine needle mulch after the first frost. Container-grown varieties may also be moved to sheltered locations like a garage or basement.

Boysenberry bushes require pruning before the first frost to manage canes and remove spent floricanes. In colder regions, insulation is critical; gardeners should apply at least eight inches of straw mulch around the root and cane area. In extreme cold, primocanes may be bent to the ground, covered lightly with soil, and topped with straw to moderate temperature and moisture.
