Soil Builder with Earthworm Castings

• Sterile Odorless Castings
• 15 Lb Half Cu Ft
• 1-0-0 Gentle Feed
• Indoor Or Outdoor Use

Soil Builder with Earthworm Castings (Wiggle Worm) is the easy, clean way to upgrade used soil without bringing stink or harsh fertilizer indoors. This 15 lb bag contains about 1/2 cubic foot of 100% earthworm castings with a mild 1-0-0 nutrient profile, offering a small immediate feed plus a slower, steady release over time. It’s a go-to for vegetables, flowers, and houseplants to improve root growth and soil texture without worrying about burn. We recommend it for houseplant top-dressing because it’s odor free and simple to apply around a full collection.

Castings also help soil hold moisture more evenly yet stay airy, which is useful in containers that dry fast or compact over the season. You can mix it into potting soil, line planting holes, or brew it into casting tea for quick coverage. Because it’s gentle, you can keep it in rotation through the season and adjust amounts based on how heavy you’re feeding elsewhere.

• In beds, line planting holes or seed furrows with 1–2 inches before planting.
• For a quick liquid option, soak 1 part castings in 3 parts water for 12–24 hours and use promptly.
• Store dry and sealed so the product stays easy to spread and doesn’t clump.
