Earthworm Castings from Earth Science

Earth Science earthworm castings are made with 100% earthworm manure and never any low-cost fillers. Professional growers have relied on earthworm castings for years to improve the soil, as they are an excellent source of organic matter. Regular use improves overall soil structure, increases water and nutrient holding capacity of soils, and encourages plant growth. They are an excellent supplement for plants of any kind.

How to apply:

  • For gardens, flower beds, fruits, trees and shrubs: Spread 1/4 inch to 1/2 inch thick layer of earthworm castings directly around the plant, and incorporate into the soil, and water. Reapply every 3 months during the growing season.
  • For potting mix: Blend 1 part earthworm castings to 4 parts of potting mix and use for your potted plants.
  • For compost pile: Spread 1/8 inch to 1/2 inch thick layer of earthworm castings between each new layer of material to be composted.



"The entire staff is amazing!"

"This is a beautiful garden store in Ft. Collins, Colo. This isn't a discount store but the quality of their plants and merchandise are good quality. We are a cactus/succulent family and we found some very healthy plants, some different than we have found previously. Large facility broken up into manageable rooms for browsing. The employees are there if you need them and the young man at the register was pleasant, knowledgeable and accommodating. If you enjoy spending time at a nursery/garden store there is no reason not to enjoy the Bath Garden Center."

"Every time I walk into Bath I’m greeted by the kindest and most helpful people! Additionally they have a fantastic selection of everything you can think of! (I’ve even bought clothing and jewelry here! It’s much more than just a nursery). Today I had the good fortune of being greeted and helped by Wyatt. I went in with absolutely no idea what to do with my garden spaces…they’re huge and overwhelming. I showed Wyatt photos of my spaces and jokingly asked Wyatt if he could just design my spaces for me….and he replied “yes!”….he took me around, asked what I liked, told me how to mix color, grasses and heights, etc…he was a wealth of info and help! I’m so grateful and I love how it all turned out! Thank you, Bath, for having great products, and a special BIG shoutout to Wyatt! You are awesome!!! (Also, Wyatt should get a bonus because I walked out with 22 perennials😂)."
