If your lawn is struggling, patchy and sparse, you may be looking for some way to improve its overall health. Worm castings are one of the best supplements that you can use to get your lawn back to healthy and looking like those yards on HGTV. What makes them so good for your grass? How do you use them to boost your lawn’s performance?
Why Worm Castings Help Lawns
Good worm castings can do a lot for your lawn because of the numerous things that they have going for them. Perhaps the biggest benefit is the microbes. Worm castings are bursting at the seams with thousands of beneficial microbes from the worm’s gut. These bacteria induce plants to grow like crazy and your grass is no exception. When you apply the castings to your lawn and water them, the microbes activate and go to work.
Another big benefit of using worm castings on your lawn is the moisture regulation. When you apply worm castings to the grass, they will absorb water and hold onto it. Then as your grass needs it, they’ll release the water to be used. It’s like having millions of tiny sponges spread out over the yard to help provide just the right amount of water. Studies have shown that worm castings reduce the amount of water that you have to apply. This means that you may not have to water as frequently, once your yard becomes established.
Once you apply the castings, they will also provide the grass many different trace minerals and nutrients. This is like giving your grass a powerful multivitamin that helps them grow bigger and stronger.
When you want to apply worm castings on your lawn, there are a few different options you have to choose from. The first option is to broadcast it onto the grass. This can be done by hand or with some kind of a spreader. Using a spreader is easiest, especially if you have a big yard. Utilizing the broadcast method gives your yard the most benefits, but it also uses more worm castings. The application rate will vary, depending on how thickly you spread it. But a good rule of thumb is that you’ll use approximately 25-30 pounds per 100 square feet of lawn. As you can see, if you have a big lawn, this means you would need several smaller bags of worm castings to cover it all. If you’re going with this method, and have a large yard, it might be best to look into getting a one ton super sack of Simple Grow worm castings.
Another popular option of application is to make a liquid form of worm castings called worm castings tea. With this approach, you use a worm castings tea bubbler to make the mixture. It takes about 24 hours to brew this concoction.
Once it’s brewed, you spray it on the grass with a sprayer. You can use a handheld sprayer or one that pulls behind a vehicle. Spraying worm castings tea is a great approach for big lawns because it allows you to use a lot less worm castings. When you make worm castings tea, it only takes about five pounds to make five gallons of tea. With that five gallons, you can spray somewhere between half an acre and an acre, depending on how thick you apply it.
This lets you spray a lot of grass with just a little worm castings. Many people who use this method also like to apply the worm castings tea multiple times to the grass throughout the growing season.
Using worm castings tea lets you get the thousands of beneficial microbes from the castings into the soil and onto the grass. When you use tea instead of the physical castings, it’s not quite as powerful, but it still works amazingly well. You don’t get the benefits of moisture retention and soil aeration by doing this.
Having the physical castings in the yard also makes it so that you don’t have to reapply as often, because the microbes can last for up to two months in the castings.
Boosting the Lawn
Overall, worm castings should work wonders for your lawn. They’ll help the overall health of the soil and create an environment that is ideal for grass growth. They’ll help get the grass the nutrients and minerals that they need. The microbes will boost the growth of the grass also.
If you reapply the castings or tea a few times throughout the spring and summer, you’ll be amazed at what your yard looks like by the end of the season. It’s great to apply worm castings after overseeding your lawn as well. More seeds will take root and you’ll wind up with a thicker, fuller lawn to enjoy.
