For use on individual plants:
Add one handful of castings to the base of any plant. Gently work it into the soil and water.
Worm castings will absorb water and slowly release beneficial nutrients to the plants for a period of two to three months.
For fertilizing garden areas or when tree-planting:
Create your soil mix with 20 - 25% worm castings.
Continue to add the castings to the area every two to three months.
You can’t overdo it! Unlike most other fertilizers, you cannot burn or over-fertilize a plant with castings.
