How to Grow Blueberries on a Patio
- 1). Combine 1 part potting soil, 1 part peat moss and 1 part bark chips in a 16- to 20-inch-diameter pot. Add a handful of sulfur and mix well. This mixture results in an acid soil mix that holds moisture but drains freely.
- 2). Plant the blueberry bush in the center of the pot. Dig the hole deep enough so that the soil line at the base of the plant is even with the soil line of the container.
- 3). Place the pot in a location with at least six to eight hours of sunlight per day. Choose a location sheltered from wind. Wind makes more frequent watering necessary and dries the foliage, making it susceptible to leaf scorch.
- 4). Water twice weekly or more often if necessary to keep the soil moist. The roots of blueberry plants don’t have root hairs, making them inefficient at absorbing water.
- 5). Fertilize monthly with an acidifying fertilizer according to the package instructions. Fertilizers formulated for use on azaleas help keep the pH in range.
- 6). Move the container into a garage or shed after the first fall frost. Blueberries need cold winter temperatures, but the roots of blueberry plants grown in containers are susceptible to damage when temperatures drop below 32 degrees F.
