How to Use Wiggle Worm Soil Builder

Vegetables and Annual Flowers

Line planting holes or seed furrows with 1–2 inches of castings before adding seeds or plants. For established plants, side-dress with approximately 1/2 cup per plant every two months during the growing season.

Containers and Houseplants

For new potting mixes, combine 1 part Wiggle Worm castings with 4 parts soil. For established container plants, apply approximately 1 inch to the soil surface, gently mix without damaging shallow roots and water thoroughly. Repeat every two to three months.

Perennials

Work approximately 1/2 cup into the soil above the root zone. Apply during spring, early summer and early fall.

Roses, Trees, Shrubs and Berries

For new plantings, blend 1 part castings with 3 parts soil and place the mixture around the planting hole. For established trees and shrubs, spread over the root area and water thoroughly.

Lawns

For new lawns, apply 20–30 pounds per 1,000 square feet and work lightly into the topsoil before seeding. For established lawns, apply 15–20 pounds per 1,000 square feet as a top dressing two or three times per year.

Worm Casting Tea

Combine 1 part castings with 3 parts water and steep for 12–24 hours. Aerate if possible, stir well and apply as a root drench. For best results, use the finished casting tea within 24 hours.
