Additionally, a mulch will help to preserve soil moisture, control weeds and keep fruit clean. Black plastic is not recommended because it elevates the soil temperature. Strawberries suffer if there is competition, so keep weeds out of the beds. Hand weeding is best because the roots are shallow. If you use a hoe or other cultivation tool, take care around the roots of the plants.
Strawberries require regular feeding to produce a good crop.
They should be fertilized at time of planting and early in the spring in subsequent years. Apply a second feeding shortly after harvest. Never apply fertilizer to strawberries late in the growing season in cold climates, as this predisposes the plants to winter injury. In warm to moderate climates, an August or September feeding is recommended. If you aren't sure whether to give your strawberries a late feeding, contact your local agricultural extension agent.
