How to Raise Blackberries

By Barbara Fahs ; Updated September 21, 2017

Few desserts are more delicious than blackberry pie, still warm from the oven. If you have enough garden space, you can grow your own blackberries, which you can use in pies, jams and other dishes to delight your family and friends every summer when they are at the peak of their ripeness. Before you begin your blackberry patch, make sure you have plenty of space and be prepared to stake or trellis your bushes to keep them from becoming unruly.

Start Your Blackberry Patch Today

Test your soil. Blackberries prefer slightly acidic soils with a pH between 5.5 and 7.0. If you need to raise the pH, add lime. If you need to lower it, add sulfur.

Purchase your blackberry plants from a nursery instead of trying to dig them from a wild location. This will assure that they are free of diseases and pests.

Prepare your planting area by cultivating it to remove weeds and other plants, and dig in plenty of rich compost to give your blackberries the nutrients they need.

Dig a hole slightly larger than the root system of your plant. In northern states, plant in early spring; in southern states, plant in fall or early spring.

Set your plants into their holes and then fill the holes with the soil you dug out earlier. If you are planting more than one plant, leave 4 feet between plants because blackberries will grow long, spreading canes that need plenty of space.

Water your blackberry bushes well throughout the summer growing months. They need about 1 inch of water per week. When it’s very hot or windy, water more.

Fertilize in spring when the plants begin to send out new growth. Blackberries respond well to a 10-20-20 granular fertilizer that you spread at their base. For every 100 feet of their row, apply 5 to 6 lbs. of fertilizer. You can also apply manure in winter if you choose that form of fertilizer.


Things You Will Need

  • Sunny location
  • Compost
  • Blackberry plants
  • Shovel
  • Water
  • Fertilizer


  • Wait until your blackberries are fully ripe and a dark purple color before you harvest them. Keep up with the harvest when they begin to ripen or the birds will eat your blackberry pies before you can make them.


  • Avoid the Himalayan blackberry because it will take over your yard---it's not recommended because of its highly invasive potential. The varieties Prime Jim and Prime Jan are good choices for home gardens.
