Worm Castings
What are Worm Castings?
Worm castings are a natural dirt enhancer produced from earthworms. Also known as vermicast - the product of worm digestion. A natural, odor-free soil amendment that is safe for kids, pets, and pollinators - no harsh synthetic salts, no burn.
Naturally full of desirable microorganisms. They produce, store, and slowly release plant nutrients - helping increase water retention, improve aeration, and anchor nutrients that would otherwise leach away with water.
Benefits
Worm castings are a fantastic way to enhance soil health and promote plant growth because they are naturally full of desirable microorganisms. They produce, store, and slowly release plant nutrients into soil to feed plants. This helps increase the soil's water retention, improve soil aeration, and anchor plant nutrients that would otherwise leach away with water.
How to Use
Top Dressing – Sprinkle a layer of worm castings on the soil surface and gently rake them into the soil.
Mix Into Potted Plants – Mix about 30% castings to your potting soil or seed starter mix.
Lawns – Broadcast with a fertilizer spreader and use 20 lbs per 1,000 sq ft · fall and spring
Lawn Benefits
Dry top-dressing
Best for overall soil health. Apply about 15–20 pounds per 1,000 sq ft. Broadcast evenly by hand or with a fertilizer spreader. For best distribution, apply just before mowing and use a mulching attachment.
Timing: spring and fall — help roots recover and prep soil for temperature changes.
Post-aeration application
Best for compacted soil. Core-aerate the lawn, then spread castings with a fertilizer spreader. Watering or rain washes nutrient-rich castings down into the aeration holes.
“We had 5 Sons Landscaping of Winterset apply Wildwood worm castings to our struggling lawn in the fall and the spring. These treatments provided a 100% improvement of our lawn. This natural dirt enhancer is safe for pets and people. Worm castings are low in nitrogen and absorb better into the soil to avoid exacerbating the nitrate issues in Central Iowa's drinking water.”
