The best worm castings for indoor plants provide organic nutrients to your plants, leaving them well-nourished and healthy all through their growing period.
Plants require certain minerals, microelements, vitamins, amino acids, etc., in order to grow and develop into healthy organisms. These materials are present in the soil but not in the same amount as required by plants.
As we all know, our soils are becoming depleted of these important nutrients. It is, therefore, necessary to supplement the nutrient content of our soil with other organic sources. The most convenient and economical way is to use worm castings which are also known as vermicompost.
This is a mixture of worm excreta or castings that contains all the nutrients needed by plants. Worm castings are easy to make and are a great addition to the compost heap.
This article will be discussing all about the best worm castings for indoor plants and the benefits of using these for indoor plants.
What Is Worm Castings?
Worm castings are the cast out of worms’ intestines and are considered organic fertilizers. They are made by worms which are used to process vegetable wastes. These castings can be used in gardens and in compost heaps.
These castings have a rich nutrient content which is beneficial for both indoor and outdoor plants. The castings contain all the essential nutrients required by plants, such as nitrogen, phosphorus, potassium, magnesium, calcium, iron, zinc, copper, manganese, etc.
The nutrients present in these castings are absorbed by the roots of the plant and distributed throughout the plant. The worms are fed with plant wastes that are rich in carbon and nitrogen. The carbon is converted into a gas called methane which is used as an energy source by the worms.
As a result of this activity, the worm casts are rich in nitrogen, phosphorous, potassium, magnesium, calcium, iron, zinc, copper, manganese, etc. These elements are converted into a nutrient-rich liquid called worm tea. This worm tea is then mixed with the worm castings to make vermicompost. The vermicompost contains all the essential nutrients required by plants, and it is also rich in humic acids and microbial life. Worms are not only used to process vegetable wastes but also to process animal wastes.
