The Word on Worm Castings: How do they work? What can they be used for?
Worm castings are the richest natural fertilizer known to humans. That’s right: as little as a tablespoon of pure worm castings provides enough organic plant nutrients to feed a 6″ potted plant for more than two months.
Worm castings stimulate plant growth more than any other natural product on the market. Unlike animal manure and artificial fertilizers it is absorbed easily and immediately by plants.
What Can Worm Castings Be Used For?
Worm Castings can be used as an ingredient of potting soil (as plant nutrients) for plants in and around the house. It can also be used as a planting additive for trees, vegetables, shrubs and flowers and because Worm Castings will never burn plants, you can use as much of it as you like.
Benefits of Worm Castings
- Removal of toxins & bacteria
- The humus in the worm castings extracts toxins and harmful fungi and bacteria from the soil. Worm Castings therefore have the ability to fight off plant diseases.
- Assists with nutrient absorption
- The worm castings have the ability to fix heavy metals in organic waste. This prevents plants from absorbing more of these chemical compounds than they need. These compounds can then be released later when the plants need them.
- Works as a barrier in undesirable soil pH levels
- Worm Castings act as a barrier to help plants grow in soil where the pH levels are too high or too low. They prevent extreme pH levels from making it impossible for plants to absorb nutrients from the soil.
- Stimulates plant growth
- The humic acid in Worm Castings stimulate plant growth, even in very low concentrations. The humic acid is in an ionically distributed state in which it can easily be absorbed by the plant, over and above any normal mineral nutrients. Humic acid also stimulates the development of micro flora populations in the soil.
- Increases water retention
- Worm Castings increase the ability of soil to retain water. The worm castings form aggregates, which are mineral clusters that combine in such a way that they can withstand water erosion and compaction, and also increase water retention.
- Reduces carbon and increases nitrogen in soil
- Worm Castings reduce the acid-forming carbon in the soil, and increase the nitrogen levels in a state that the plant can easily use. Organic plant wastes usually have a carbon-nitrogen ratio of more than 20 to 1. Because of this ratio, the nitrogen is unavailable to plants, and the soil around the organic waste becomes acidic.
How to use Worm Castings:
Use 20 to 30% Worm Castings with sand as an excellent germination mixture. It will also ensure continuous and lush growth for about three months, without you having to add any other plant food.
As a Soil Conditioner
If you hoe a layer of barren soil, add a layer of Worm Castings and give it some water, you will be surprised at the growth of your first season’s plants.
As a Fertilizer
Sprinkle Worm Castings around the base of plants or lightly dig it in, and then add water. They can also be sprinkled on a large scale with a spreader. Remember: you cannot use too much Worm Castings, they cannot damage your plants.
As a Liquid Fertilizer
Worm Castings can easily be mixed with water. Use 1 cup Worm Castings for every gallon of water and wait 1 week. This liquid mixture can be used as an excellent fertilizer or leaf foliate spray. It also helps to control insects. Many people prefer this method of application.
We have known for hundreds of years that earthworms are the best way to improve plant growth and to increase plant yield, such as fruit.
