Earthworm castings. Worm castings are unique and secret ingredients, which improves the growth of plants.

There are many worm casting products available on the market. However, not every kind of product is the same.

Just like we have different kinds of pizzas, there are different types of worm castings.

Although some of the products available on the market are good, there are some, which are just simply amazing as compared to others.

In today’s article, I am going to review one such amazing worm castings product – i.e. 100% Pure Worm Castings – made by Perfect Plants.

Before I tell you about the product, let me first give you an overview of the company. Read on!

Perfect Plants Company

Perfect Plants is a family-owned business operating a plant nursery in North Florida. The company’s mission is to promote environmentally friendly practices and encourage farmers and gardeners to adopt organic practices.

The Perfect Plants Company was found in 1980. Since then, they are making substantial Earthworm-Castings-Perfect-Plantsefforts to develop a wholesale nursery business.

The company is working on an eco-friendly vision to produce better plant products following the ethics and protocols of the industry.

The information on their official website helps thousands of people who want to grow plants in the field and home gardens.



How to choose worm castings?


There are different types of worm castings. So, which one you need will depend on your specific needs and/or requirements.

However, there are a few factors that you need to take into consideration before choosing the best product.

These recommendations are based on the research, expert opinion, and experience of the Perfect Plants Company.


Food Source


The first thing or factor that you should consider is the food source. When you opt to buy regular manure, you want to see and understand what the animal has produced based on its eating.

For instance, if you have bought the cow manure for the fertilization of your home garden, you will want to see that the animals had been consuming nothing but clean, organic waste. So, be careful with the food source of the animals.

There are some worm castings, which are no different than compost – essentially – because the earthworms – for instance, were eating junk.

Yard clippings without harmful pesticides and table scraps are organic waste, which is what would you usually want in the worm castings.

So, the purer the source of food, the better results that you will obtain in your home garden.

If the provider of the worm castings does not tell what food they give to the words, there is a high possibility that you will get harmful humus, which is not good for the soil and eventually will be dangerous for the growth of plants (and you if you eat them).



Worm Castings Purity Percentage


Another important factor or variable you need to consider is the purity of the product. When it comes to purchasing worm castings products, you must check or verify the quality of the ingredients.

For example, you must look for the one that is 100% organic and contains soil-enriching nutrients so that you observe the natural and organic growth of plants in your garden without any problems.

According to Perfect Plants, many producers put a mixture of worm castings and dirt in the product’s bag.

Then, they call it 100% pure worm casting. In reality, you are not getting what you need for your garden plants.

So much so, the ratio of worm castings to dirt is somewhat better in some products than in others.

Today, there are products available on the market, which are only 80% castings and the rest of 20% are all junk, tiny rocks, bedding, and dirt.

It is important to know that you must refrain from buying earthworm castings from unreliable manufacturers.

If you are looking to buy the best organic worm casting fertilizer for your home garden or field, you must look for a product that is 100% organic.

It is because you don’t want a product’s bag that is filled half with the castings and half with pebbles and dirt.

When you are after castings, it is vital to look for a worm castings product, which is 100% earthworm castings. Again, if the product’s packing does not mention the percentage, you must avoid it.


Worm Bedding


When it comes to producing the earthworm castings, they are placed into a specific type of bedding – so that worms can work effectively to breakdown the organic material.

There are numerous bedding, which people can use – and some of them are quite better than others.

The bedding is important because it helps in contributing to the quality and efficiency of the end-product.

For instance, peat humus, dark soil used as bedding will yield much better results as compared to sandy or silt soil.

You may not know what type of bedding was used. However, it can have a significant impact on the efficacy and quality of castings, which are produced ultimately.


Trusted Company or Brand

Earthworm-Castings-Fertilizer Earthworm castings are becoming one of the most popular organic fertilizer. With the increase in popularity, there are many producers companies in the world – particularly in the United States.

Due to this, you will find many companies that claim to produce high-quality worm castings.

However, in reality, you will end up buying a low-quality product, which won’t even waste your money and time but also cause harm to the plants in your garden.

If you want to invest your hard-earned money to buy earthworm castings, you don’t want your product from a low reputable company, which has no intention of environmental-friendly practices but to earn money.

On the other hand, you need to choose a company that best fits your needs and provides you with the best quality – i.e. 100% organic worm castings product.

In this regard, the best we can find on the market is ‘Perfect Plants,’ which is operating since 1980 and produce some of the finest quality organic fertilizers.

  • Can be expensive when buying them from a manufacturer

  1. Hi Catherine, Never thought of using Worm Casings before. You make some very good points and lots of good information here. Thank you for sharing!

  2. Wow! I happened on your site and what a pleasure to see an honest review of organic worm castings of all things.
    Could you possibly give your opinion on worm castings versus worm tea? Meaning if you have a source of earthworms and water is drained from the bottom of the container they are kept in?
    Thanks again for your efforts.

    1. You are more than welcome. They will both boost the health of the soil in the same way. The key difference between the worm tea and worm castings is the absorption rate. The tea will work quicker than casting. The most cost-effective way to use worm castings or worm tea is to maintain a farm yourself. However, some people do not have the time or space for this. I would recommend that those people purchase them online. I would recommend this earthworm tea.

  3. This is exactly what I needed to read! I am starting my first veggie garden in the spring on our little farm and I have been soaking in all kinds of information to get prepared for it. This article helped so much to know how to help my soil and I am excited to hopefully yield more fruits and veggies from my garden because of it!

    Thank you so much!


    1. You are more than welcome. If you have space then I would recommend building your own worm farm to create earthworm tea as this will be much cheaper and effective in the long run.

  4. I am no stranger to worms and worm castings, and since I live in farm country we judge our soil by how many worms and worm castings our soil contains. I have never had to purchase worms or worm castings, but I know many people in the cities probably do.

    I have little red worms and big nightcrawlers in my garden soil, and every time I dig up my soil I am thankful for all those worms


  5. Very happy to have read this article on worm castings as we have used a Canadian equivalent product in our greenhouse operation in Canada. Everything you have written about in your article was true of the product we purchased although we did not plant directly into worm castings but mixed it with our topsoil and organic beef compost which produced an excellent growth medium for starting seedlings and plugs. Getting a plant a strong start before being transplanted is paramount to a successful field planting. Thanks for this wonderful review on a product that should be promoted.

    1. Hi Justin. I am happy to hear that you have experienced great success using a similar product. Yes, strong starts are essential before the transition. Thank you for sharing your experiences and views on this subject. I hope to hear from you again soon.
