How to Fertilize Strawberry Plants

By Hollan Johnson ; Updated September 21, 2017

Strawberries are perennial plants, but they have extremely shallow roots. Several varieties of the little red berries are hardy from zones 5 to 8, so they will grow under many conditions. One of the best ways to encourage strawberry plants is to fertilize them properly. Doing so will give you plenty of fruit for years to come.

Prepare the soil before you plant the strawberries. Add compost or manure to your soil to improve its quality. This will give your strawberries a boost without the use of fertilizer.

Add 10-10-10 fertilizer about a month after the strawberries are planted. Add about 1 lb. of 10-10-10 fertilizer per 20-foot row of strawberries.

Fertilize strawberries more than a year old once a year after they have borne fruit, usually in mid- to late summer. Be sure to fertilize strawberry plants before September.

Add half a pound of 10-10-10 fertilizer to each 20-foot row of strawberries.

Apply the fertilizer around the base of each strawberry plant and water well. Apply about an inch of water to each plant.


Things You Will Need

  • 10-10-10 fertilizer
  • Manure or compost


  • Fertilizer sitting on the leaves will burn them.
  • If you fertilize strawberries in the spring you will get large, soft berries.
