Answer This Question

I use worm castings on all my vegetables, including Tomatoes & Peppers, which are Nightshade Crops along with Potatoes. I don't see any reason why Worm Casting won't nourish any plant. Regardless of if it's planted in the ground, a container or a Bag!

      Hello, can this be used on existing grass that needs some help? If so how is it used? Diluted or just sprinkle straight on the grass? And how much area does one bag cover being used as a fertilizer like this?

      Answer This Question

      Dear Valued Home Depot Customer, We have reached out to the manufacturer and their reply is, Hi! Yes, you can mix the worm castings in with grass seed and scatter across the lawn to grow grass. If you can till the worm castings into the soil at 1 part worm castings to 3 part soil, with the grass seed mixed in, then water plenty — that should do well. Think of using 1/4" worm castings per area, mixed with grass seed that you want to regrow. Water plenty!

        I just bought two bags of these at the Home Depot store in Hays, Kansas and they have these tiny little white grass like stems and root attached. Should I be alarmed? Should I pick out the little sprouts or what should I do?

            I bought this for one purpose (to help my cactus), but after learning more about worm castings I have started using it with many of my other plants, too. My baby shrubs and peppers are thriving! I would describe the castings as feeling just like a kind of pure soil. Not particularly dense, and smooth, no chunks. I now plan on keeping a bag on hand at all times.

            Great boost for seedlings and established plants – gentle but effect
            I’ve used a lot of soil amendments, but earthworm castings are hands-down one of my favorites. This stuff is mild enough to mix right into the soil when transplanting seedlings, and it gives them a strong start without any risk of burning. I also top-dress established plants every few weeks and water it in—keeps them healthy and green. HandyFireman tip: Mix a few handfuls into your potting mix or raised bed soil before planting, then add a thin layer around the base of your plants every month. It feeds them slowly and improves soil texture too. Great for tomatoes, herbs, houseplants—you name it. Highly recommend if you want a natural, no-fuss way to keep plants thriving.

              After mixing the Earthworm Castings with my soil, I noticed that both my indoor and outdoor plants began to grow larger and more vibrant. I believe this mixture enhances the nutrients in the soil. Overall, I am very satisfied with this product.

              Great for helping our plants and trees to be happy, even in the Az desert. I use it annually. Better than toxic fertilizers. Makes our soil productive

              Very shortly after using this product I noticed small white soil mites all over the surface of my soil. When I scraped off the first inch of soil I saw it was completely loaded with white mites and some weird tiny worms. Do not buy this stuff.

                Earthworm castings make plants healthy and large! I use on both inside and outside plants!
                I'm so glad I found this! My plants have never grown as quickly as they have this year! Earthworm Castings make the difference!
