Why Use a Worm Composter?

Best Worm Composter

Worm castings are not only right for your plants, but the organic manure has all the nutrients that your plants need. The worm castings are safe, and you can apply them directly to the plant roots, without the risk of burning. That means you can throw a generous pile on the roots of your tomatoes without worrying about anything – they can be a top dressing, a side dressing or even some mulch, your choice.

But what is the big deal about worm castings? The Benefits of Vermiculture

The main benefit associated with worm castings is the quality of the end product that the worms produce. Worms ingest the surrounding organic materials, and in the process end up refining them. The process refines the trace elements, as well as, the nutrients, reducing them to their most usable form, and having a neutral PH.

Vermiculture or vermicomposting process produce digested soil full of the good microbes, which help the plants keep diseases at bay, and thrive.

As a soil amendment, the worm product does not have any odor and are gentle on the plants. The castings have more nitrogen than your typical garden soil, making them ideal for those kales you have been planning to start planting for some time now. It also makes the soil more absorbent, so that it can hold more moisture to the benefit of the plants.

The vermicomposting process introduces the good little guys in the soil. The good bacteria and other microbes make the soil sufficiently healthy for the plants. They also contain humic acid, which plays an important role in plant nutrient absorption.

Research shows that planting seedlings in worm castings improves germination, as well as, seedling growth. In other words, worm castings are an ideal food for the plants.

Another interesting research indicates that our little wriggly friends help remove toxins and heavy metals from the soil. It means that worms can assist in the land reclamation of contaminated sites. It also means that the process can help keep the garden soil at the best level for the plants.

Making Worm Castings

Vermicomposting is not a complicated exercise if you have the necessary information on how to go about it. Typically, you use a worm box or bin, made or purchased. If you prefer to make your own worm composter, ensure it has dimensions of 8 by 12 inches in depth – deal. The box should also have drainage holes at the downside.

Making the composter too deep leads to awful smells. Small is better if you want something under your sink or something like that.

You should also place a layer of newspaper strips and sand at the bottom. Follow this with another layer of leaf litter, soil and moist newspaper strips. Introduce the worms with garden waste and kitchen scrap for the process to begin.

Factors to Consider when Choosing the Best Worm Composter

There are a few things that you may need to look out for when selecting vermicomposter for your garden, and the following are some of them.

Drainage

Drainage is important. Ensure your choice has decent drainage with a spigot to take the worm tea out. The worms can drown if there is too much of the liquid from food wastes such as watermelons and cabbages – leachate.The drained leachate is nutrient-rich, but since it has not gone through the worm’s guts, it may, therefore, contain harmful pathogens, and not ideal for the edibles. Use the leachate on flowers and lawn.

Size of the composter

The amount of organic waste varies depending on the size of family and amount of food consumed. If your family is gradually expanding, you will need a bigger worm composter with sufficient space for the worms.

Harvesting

You will eventually need to retrieve the compost, and that requires you to remove the worms first together with their food. The process can be messy, but with a decent composter, you can achieve easy retrieval and fewer disturbances for the colony.

Shade and VentilationWorms don’t like too much sunlight, and so an opaque composter that blocks light is the best. Avoid those that easily allow light inside them. The worms also need to breath; make sure the composter has sufficient ventilation to let fresh air in.

Conclusion

The best worm composter is a darling for gardeners. It converts kitchen waste into something useful for plants. Any of the above can make decent composters, but Hungry Bin Flow-Through Worm Farm is in our opinion, the ideal.

It has an innovative design that makes usage an easy task. The worm factory can produce up to 4lbs of worm cast on a daily basis, and it is low maintenance.
