Earthworms may seem like a pest on the surface, but they are helpful to the environment and can contribute significantly to your garden. Earthworms build tunnels underneath the soil, enriching the soil and fostering healthy microbes. They also leave behind organic droppings, and that promotes rich soil. Why We Need Worms? Because they are great for your garden's soil. You do not have to worry about earthworms threatening your flowers, veggies, or fruits since worms are primarily concerned about whatâ€™s going on underground instead of going above them. If you have any soil problems, try attracting earthworms to your garden. You can even buy worms at your local bait shop, allowing them to reign free in your garden. Make sure that your soil is enough to attract earthworms. Earthworms are resistant to nitrogen, which can be problematic since soil needs a good amount of nitrogen to thrive. To solve this problem, allow any manure or compost containing a high nitrogen level to sit for a few days to dilute the potency. It also depends on what plant you want to grow; some plants require a low nitrogen level. If you use pesticides to get rid of any pests, earthworms will be affected. If you are trying to get rid of insects, keep the spraying of pesticides to a minimum, and make sure no chemicals reach the grass where Worms reside underground. Also, you may want to try natural pesticides that are targeted toward a specific pest. Try using organic fertilizer since it contains natural properties that make earthworms feel at home. Inorganic fertilizer contains more acidic chemicals and is hostile to the earthwormâ€™s environment. If you want to attract earthworms to your garden, use organic fertilizer and soilâ€”earthworms like organic mulch that is leafy. Wooden mulch is more problematic for worms to sift through.
