Your soil deserves good organic nutrients to aid in the growth of your plants, which is what worm castings provide for you. Worm castings are essentially worm poop loaded with humic acid, nutrients, minerals, and nitrates, boosting soil strength and improving crop yield. It is critical to understand how to use worm castings in soil, planting holes, and potted plants to improve gardening.

Worm castings are one of the most natural and organic soil materials with various benefits. Earthworms burrow into the soil, consuming the food in your compost and leaving castings in their wake. In addition, they leave an opening for air and water to pass through, thereby bringing about soil aeration, which further strengthens the soil.

This is inexplicably a fertilization method for your plants' organic nutrients, growth, and yield. No one goes into gardening expecting to have lousy crop output; the reverse is the case. Your vegetable garden will greatly benefit from the bacteria that worm casting or worm casting tea can provide. Plus, these red wigglers are beneficial microbes that repel most pests. Instead of pesticides, use worm castings for green waste and a more nutrient-dense soil and plant nutrition.

How Much Worm Casting Should I Add to the Soil?

Plant growth depends on several factors, including composting worms and animal manure. Simply mix worm castings or worm tea with your potting soil when transplanting vegetable plants or garden beds before planting. This approach guarantees improved garden soil for container plants.

On another note, you will not harm your garden beds by adding tons of earthworm castings to your soil. Although a handful of worm castings' organic matter would do wonders for your organic garden, worm tea could also be quite beneficial. However, for measured worm castings, use one-fourth to one-half cup per 100 square feet—also, one cup of potting soil for mature, established plants.

Can You Plant Directly Into Worm Castings?

Worm manure is a highly potent and organic material for healthy plants. In other words, using pure worm castings in your planting hole is encouraged for better yield. Moreover, your plant's roots will not burn using this method, unlike chemical fertilizers that have a higher probability of doing so.

If you are concerned that your earthworm castings will not be enough for your plant, you can make worm casting tea and add it to the soil. As a liquid fertilizer, worm casting tea energizes the potted plants' roots and makes a good seed starting soil. In addition, actively aerated compost tea hydrates your vegetable plants and is advantageous for container plants and hanging basket plants. Worm compost tea makes worm castings go a lot farther than its solid component.

Are Worm Castings Good for All Plants?

Planting directly on worm castings is suitable for all plants except those susceptible to salt and worm castings with a pH of 7 to 8. You can also harvest worm castings on your own. Earthworm castings slowly release fertilizers into the soil, so you can apply them in large volumes, in contrast to fast-acting fertilizers. It also reduces plant diseases. 

Worm casting is a slow-release fertilizer, and as such, it works exceptionally well for seed germination, existing plants, and transplant survival. Furthermore, by using worm castings or worm tea in your soil, you will benefit from the enhanced root growth of your plants and have a stable soil structure.

Ways to Use Worm Castings in Soil

As mentioned above, worm castings work if you want to nourish your soil, power plants, and improve their yield. There are several ways to use them in planting, such as:

Mixing With Soil

Worm castings are especially good for seedlings, and they protect the roots of vegetable plants, thereby helping them grow and increasing their yield. When planting, mix one cup of worm casting with a cup of potting soil. You can use the exact equivalent or higher for mature plants or transplants.

Worm Castings Tea Spread

The benefit of liquid fertilizer is its ability to distribute rich nutrients like humic acid evenly. It serves as protection for the plant's exterior, keeping away pests and aiding the healthy growth of the plant. With this method, you will spread the warm castings farther, and it's better than synthetic fertilizers for fertilizing vegetable plants.


If you use a dry spreader, spread and use worm castings over the area you intend to plant. With this method, you will ward off pests and protect the exterior of the plants as well. You can also spread the castings with your hands, which works well for fields.


How Long Do Worm Castings Last in Soil?

When applying worm castings, you must know that soil can lose its organic matter and rich worm manure can become unhealthy or, better still, less potent. To avoid this, you need to plan the shelf life of the soil before usage. You should have a worm farm, worm bin, and own worms for homemade worm castings to get started. If you plan to purchase worm castings, choose red wiggler worms since they make the best slow-release fertilizer for power plants.

Depending on the storage method, you can store pure worm casting soil for six months or longer to fertilize vegetables. Furthermore, it would help if you stored composting manure soil in a container or paper bag, keeping it moist and allowing it to breathe but not exposed to the weather. Also, keep the stored worm manure soil away from UV lights and store it at a stable temperature. In addition, if things are not going as planned with the long-stored soil, add more worm castings to enrich the soil further. 


Now you know how to use worm castings in the soil! There is everything to gain by adding worm castings to your veggie garden and container plants. Whichever warm-casting planting method you use, you will achieve your objective of heightening your plant's nutrients.

Worm casting is an excellent alternative to animal manure with its rich organic material. Furthermore, you can plant directly on worm castings by using them in your planting hole. Also, it produces healthy plants and gives the soil organic nutrients.
