16 lbs Organic Red Wiggler Worm Castings – Premium Plant Food & Soil Amendment
Our biggest bag of black gold. These 100% organic red wiggler worm castings are the rich, living compost our Eisenia fetida worms make from their bedding and food — screened, bagged, and ready to feed your garden. Sixteen pounds goes a long way: raised beds, rows, containers, and whole Asparagus garden plots.
Worm castings are nature's perfect plant food. They are packed with slow-release nutrients, beneficial microbes, and enzymes that wake up tired soil, grow stronger roots, and push bigger blooms and heavier harvests — and unlike chemical fertilizers, castings never burn your plants, so you can use them generously anywhere.
Why gardeners love our castings:
- 16 lbs — our best value size for beds, rows, and big gardens
- 100% organic worm castings — no fillers, no chemicals, no burn
- Improves soil structure, drainage, and water holding
- Loaded with beneficial microbes that keep plants healthy
- Safe for vegetables, flowers, herbs, houseplants, lawns, and new seedlings
How to use: Mix a handful into each planting hole, work 1–2 inches into bed soil before planting, top-dress around growing plants, or brew it into worm tea. A little at transplant time makes a big difference all season.
