• Annual  & Perennials Flowers:   Mix 1/2 cup into the soil above the plant's root zones.  Use more for larger plants.  Apply castings 3 times a year -- spring, early summer, and early autumn.  For planting beds, mix 6 inches of compost into the soil and add worm castings at a rate of  8 Liters per 100 square feet. 
• Established Plants and Potted Plants (indoors or out):  Side dress during growing season at a rate of 1/2 cup per 6 inch pot or 1 cup per linear foot.  Repeat every 2-3 months.  You can also use worm castings as a top dressing by placing on top of your plants' root zone 1-3 inches of castings annually. 
• New or Transplanted - Roses, Trees, Shrubs and Berries:  Mix 1 part worm castings to 4 parts soil or planning mix.
• Vegetables:  Line bottom and sides of plant holes and seed furrows with 1 to 2 inches of worm castings.  Set seed or plants in place and cover with soil.  Side dress during growing season at a rate of 1/2 cup per plant or 1 cup per linear foot of row once every 2 months.
• Lawns – New:  Apply worm castings at a rate of 8 quarts per 100 square feet of lawn area and work lightly into the topsoil. Mix in grass seed and water well.
• Lawns – Established:  Apply worm castings at a rate of 8 quarts per 100 square feet and repeat every 45 days during the growing season.
• Casting Tea:  Simple non-aereated tea: Soak 1 part castings in 25 parts water for 12-24 hours. Casting tea is excellent for fruiting, flowering or difficult to access potted plants.  Use as a leaf spray and/or root drench.
