Blackberries and raspberries are summer and late-fall favorites in the garden. Both forms of fruit often are picked and shipped before the fruit is fully ripe. However, ripe berries do not travel well, and commercial varieties often lack the full flavor found in berries produced locally. For this reason, fresh-grown blackberries and raspberries always will reign over their conventional store-bought counterparts. Since the genuses of berries are very similar, they often are planted together.
Select a site in full sun to plan blackberries and raspberries that has good drainage and wind protection. Install a wind barrier such as a fence or wall if the site receives ample wind.
Pull out all weeds to ensure that the roots of the blackberry and raspberry plants can establish themselves without competition. This also means removing any plants that may compete for soil nutrients, water or sunlight.
Add manure or compost to the soil. Turn the soil with the added manure or compost, or spread the supplemental mixture over the site the fall before planting. Brambles benefit from compost or manure, and the supplemental mixture will protect the soil from nutrient leaching during the growing season.
Prepare planting holes on opposite sides of a single-post support mechanism.
Plant both bramble bushes in shallow pits 2 to 4 feet apart and make sure each has access to some form of support, such as the fence post or trellis.
Trim the bramble plant to encourage rooting. Cut the bramble back to approximately 6 inches from the soil and water well to ensure proper rooting in the first season. This allows the plant to cultivate roots and will help establish a healthy root system for the ensuing seasons.
