Frequently Asked Questions

What exactly are worm castings?

They are the unprocessed manure of earthworms, an organic-matter-rich soil amendment with a broad mineral profile. Because they are left unprocessed, the material retains the microbial activity earthworms build into it.

How do I apply worm castings?

Apply them as a top dressing, side dressing, or work them directly into soil at planting time; all three methods are effective. Many gardeners also steep castings to make a compost tea for watering in.

Will castings burn my plants like some fertilizers can?

No, worm castings are gentle and well suited to frequent application without burn risk. That makes them forgiving for houseplants and seedlings where stronger fertilizers can cause damage.

What types of growing are castings recommended for?

Household plants, urban gardens, lawns, golf courses, nurseries, and greenhouses all benefit from this amendment. It is not crop-specific, so it fits most general soil-building programs.

Can worm castings be combined with other fertilizers?

Yes, castings are commonly layered with other organic fertilizers as part of a broader soil-building program. Many growers mix them with rock dust or greensand to round out the mineral profile.
