Q: How can I encourage more earthworms in my soil? — Tracy Musicc
A: Any and all natural, organic amendments and fertilizers will encourage earthworms. Well-made compost may be the most efficient way to go, especially if made with pumpkin, which worms love. Rock minerals, such as lava sand, basalt, and Azomite, are also important for encouraging worms.
While adding good stuff to the soil, stop using toxic pesticides and high-nitrogen synthetic fertilizers, which are damaging to soil microbes and other life, including earthworms.
Watering properly and keeping the bare soil around plants covered with a mulch of shredded native tree trimmings is the final step to encourage beneficial soil life. I also have good results drenching my soil monthly with a mixture of 1 cup of concentrated compost tea and 1 ounce each of apple cider vinegar, liquid seaweed, and liquid molasses per gallon of water.
