Strawberries grow low to the ground and last for several years, with good winter hardiness into northern states like Maine. These plants require specific growing conditions, though, including protection from pests, and quick, efficient drainage. Grow strawberries in grow bags to protect them from pests and fungus, and to move them to new locations throughout the year.
Retailers produce grow bags made of soft material or felt, in a range of shapes and sizes, as more flexible potting options. Choose grow bags that hold at least 10 gallons of soil for strawberry planting, or create your own grow bags with 10- to 12-pound bags of organic compost.
Slit bags of compost from end to end and spread them wide for ready-made strawberry planting situations. Spread retail grow bags open and fill them with compost, or a mixture of organic compost and quick-draining potting soil. Strawberries grow successfully in this rich, moist and nutritious foundation, while grow bags provide new pest- and fungus-free soil for the seedlings.
Location and Planting
Plant strawberries in fall or spring in U.S. Department of Agriculture Growing Zone 8 and higher, and in spring in Zone 7 and lower. Place the grow bags in spots that get full sun for eight hours a day for full strawberry growth and blooming, and plant the seedlings in a row down the middle of the opening. Give each seedling 10 to 15 inches of space for growing and expansion. Plant the seedlings in shallow holes so the root balls sit just below the surface.
Water grow bag strawberries with 4 inches of water a week to maintain good soil moisture; these are isolated growing situations, and soil will dry more quickly than it would in the outdoor garden. Give strawberries side dressings of 12-12-12 fertiliser in midsummer and then again in fall. Strawberries produce fruit in their second season, and fall feedings help to set the next year's fruit.
