Wiggle Worm | Pure Worm Castings Organic Fertilizer 15lbs

Wiggle Worm's castings are 100% earthworm castings, screened so the bag holds only castings and not vermicompost or leftover bedding. They're OMRI Listed for organic production. This is the 15 lb bag.

Castings are a gentle amendment that won't burn roots, seedlings included. The fine particles loosen heavy mixes and improve drainage, help light soils hold moisture, and feed the microbes around the roots. They're odorless, which makes them easy to use on houseplants.

How to use: in containers, mix 1 part castings to 4 parts soil, or top-dress about 1" on established plants every 2-3 months. For vegetables, line the planting hole with 1-2" and side-dress about 1/2 cup per plant every 2 months. For casting tea, soak 1 part castings in 3 parts water for 12-24 hours and use within a day.

The 15 lb bag covers lawn work too: 20-30 lb per 1,000 sq ft worked in before seeding.
