How to Grow Blackberries Indoors

By Carole Ellis ; Updated September 21, 2017

If you love the taste of home-grown blackberries but your local climate does not support the plants, then you may decide to try your hand at growing these tasty fruits indoors. While you must accept upfront that indoor fruit gardens seldom rival their outdoor counterparts in productivity, you can certainly grow enough blackberries in your home to enable you to enjoy these delicious fruits all year long. It may take a bit of extra effort, but your indoor blackberries will reward you with sweet, delicious fruit.

Cut a piece of screen about the same size as the bottom of your pot and place it in the bottom of the pot. This will prevent the soil from washing out of the pot as moisture drains after you water the blackberries.

Mix up your soil. Indoor fruit bushes grow best in a mixture of peat, bark, perlite and sand. Use equal parts of each of these media, and mix them thoroughly in the pot. Fill the pot nearly to the top.

Plant your blackberry seedling. If you have multiple seedlings in the same pot, they should be about 24 inches apart from each other. Cover the roots completely and ensure that the soil is holding the plant firmly in place.

Place your blackberry plant in full sun. Since it is growing indoors, you need to either place it in a window that gets sun for at least eight hours a day or keep a sun lamp on it for that length of time. Some people also experience success using florescent lights.

Water your blackberry daily. Blackberries need about an inch of water each week. Do not wait for the soil to get dry before giving your plant more water. However, if the soil is bordering on muddy, then you can forgo watering for a day. Add mulch around the plant to help hold in the moisture.

Use a dowel rod to provide support for your blackberry plant as it grows. Loosely secure the plant to the dowel rod with twist ties if you see it becoming saggy or trailing out of the pot onto the ground. Over time, you will see a steady harvest. Ever-bearing plants can be used to harvest fruit year-round indoors, while seasonal varieties may require more coaxing or need a rest after their harvest.
