How to Fertilize Junipers

Overview

You have many options when choosing a type of juniper (Juniperus spp.) to grow--after all, over 170 types of junipers exist. Upright varieties, like the Armstrong or Arcadia varieties, are grown as shrubs while prostrate varieties, like the San Jose and the Andorra, grow close to the ground and make for a hardy ground cover. Whatever juniper you choose, fertilize the plant regularly to ensure healthy, vigorous growth all year.

Step 1

Fertilize the juniper shrub when you plant it. This gives the juniper the jolt of energy it needs for quick establishment. Mix 2 tsp. of 10-10-10 all-purpose garden fertilizer into the soil around the planting location, according to the University of Georgia.

Step 2

Feed the juniper shrub again in the early spring. For the best results, use a complete fertilizer labeled for use with shrubs. The University of Georgia recommends a 12-4-8 or 16-4-8 product. Apply 4 oz. of fertilizer in the 50 square feet of soil surrounding the juniper plant.

Step 3

Water the fertilized soil lightly to help carry the fertilizer nutrients into the ground. Apply enough water to moisten the ground to a depth of 3 to 4 inches.

Step 4

Repeat the fertilization process at the end of summer.

Tips and Warnings

  • Don't get the fertilizer on the juniper shrub's foliage. The fertilizer will burn the plant's leaves.
