How to Fertilize Blueberry Plants


The blueberry has earned the reputation of being a super fruit with healthful antioxidant powers. It also brightens the garden, growing up to 6 feet high and bearing clusters of white flowers during the spring. By midsummer its crop of sweet blueberries has come to fruition, and in the fall its green leaves turn deep red. The fine roots of the blueberry plant cannot tolerate strong fertilizers.

Step 1

Inspect the leaves of the blueberry plant. If they are uniformly pale, they are lacking nutrients. If they are green and healthy looking, do not fertilize.

Step 2

Plan to fertilize in the early spring, only if the blueberry bush needs it, as indicated by uniformly pale leaves.

Step 3

Spread cottonseed meal (6-3-2) by scattering it beneath the branches of the blueberry plants. Use about 2 oz. per plant.

Step 4

Repeat step 3 in June, if needed.

Tips and Warnings

  • Blueberries are sensitive to overfertilization. Do not use nitrate forms of fertilizer.
