Blackberry bushes will produce fruit for up to twenty years with the proper care. They are a favorite ingredient in pies, cobblers and preserves and can be stored in the freezer for months at a time. Plant a young blackberry bush in early spring as soon as the chance of frost is over. Though blackberry bushes usually don't produce fruit in their first year, it is a crucial time of establishment for the plant.
Find a spot in your yard. Blackberry bushes do best with full sunshine, very little shade and well-drained soil. A location with too much shade will inhibit fruit production.
Prepare the soil. Till the soil into a loose mixture free of clumps and rocks. Remove any weeds. If your soil is lacking in nutrients, add fresh compost or a bag of potting soil to the area where you will plant your bushes.
Dig a hole. Dig a hole slightly deeper than the blackberry's current container and wide enough to spread the roots out fully when planting.
Plant your bush. Remove the plant from its container and gently separate the roots. Spread the roots widely and place the young plant in the hole. Spread soil around the base of the plant until all the roots are fully covered with at least an inch of soil.
Spread mulch. Spread a layer of high quality mulch around the base of the plant. This will keep the soil moist and prevent an onslaught of weeds.
Water immediately. Give your new plant a good watering by fully wetting the planting area with a hose. Blackberry plants need lots of water, especially during fruit production. Give your plants at least 1 inch of water each week.
Add fertilizer. Purchase a general fertilizer and use twice a year during spring and autumn for plump fruit and healthy leaves.
