How do you use worm castings in your home garden?


  • Worm castings should be worked into the soil in the spring prior to planting.  This should take place as soon as the ground becomes workable.  Work 1" - 4" of Circle M Castings into the top 4″ – 6″ of soil.
  • When preparing the soil, use 10 lbs. of Circle M Castings per 100 square feet. Side-dress when plants are three to four inches high and side dress again during growing season, for optimum growth.


  • Add 1 part of CircleMCastings with 2 parts (fertilizer-free) peat or coconut coir based seed starting mix.


  • Incorporate 2 – 4 cups into top 2 – 3″ of soil in Spring.


  • Seeding: Line Seeding trench, hole or bed.
    Transplanting: Add ½ – 1 cup of Circle M Castings to the planting hole.
    Established plants: Work 1 – 2 cups into top 2" – 3″ of soil around the plant.


  • When transplanting bare root or container trees where you want maximum growth and fruit production it is best to use a 50/50 mix of cured compost and Circle M Castings. Most all of the fruit and citrus trees will go into production in half the time. Ornamental trees will experience five times the normal growth, nut trees will take longer to get into production and the rate is not as dramatic as the other trees.
  • After planting in the spring,  the trees will require 5 to 7 lb. of Circle M Castings applied in the fall. Apply the castings by the top dressing from the trunk to the edge of the drip line.
  • With established trees top dress with 5 lb. of Circle M Castings two to three times a year. The spring planting period will be the most productive time to apply castings, followed by further applications every other month during the growing season.
