As soon as the winter season ends and spring arrives, people work in their gardens again. The type of soil you will use plays a significant role in the healthy growth of plants and herbs. If the fertilizer you are using is not good, you will surely end up with unfavorable results. Most people choose either horse manure or cow manure, but we have another solution.

Worm castings and chicken manure are both viable solutions that are easy to find. However, deciding which one is best is not an easy task. That is why we have done the research for you. Here is everything you need to know about worm castings vs. chicken manure to help you decide.

Our Pick

When comparing worm castings and chicken manure, we believe worm castings to be the better fertilizer. Worm castings, like Simple Grow, are more cost-effective than manure. In addition, worm castings are easier to collect for vermicomposting than chicken manure. You can make use of your worm compost within three months, whereas waste takes up to six months to produce results. Moreover, worm castings reduce the chance of weeds growing in your garden.

About Worm Castings

The best thing about worm castings is that they are an organic fertilizer naturally produced from earthworms. Earthworms are there to help fertilize your soil, and the best way to do so is to provide food for the worms. It might be hard to believe, but their excrement fertilizes the soil.

This fertilization method is cheaper than others, plus it increases water retention in the ground. Even if you do not have anything to feed them, you can add the worms to your garden and watch the magic happen. They will forage for food themselves, saving money that you would otherwise spend on feed.

Worm castings are organic material, which is excellent for plants, and they enrich the soil providing the plants with the essential nutrients needed for their growth. The best part is this fertilizer works for all plants, and you can even use it directly on plants without the risk of burning them.


More Porous Soil: Worm castings make the soil more absorbent, and the soil retains water to stay moist for a longer time. This way, moisture is readily available to plants and prevents the ground from drying out completely.

Superfood of Garden Plants: Studies show that worm castings can make plants grow faster and healthier than any other fertilizer. Worms can remove all the heavy metals and other toxins from the soil, making the ground ideal for all plants. 

Natural Process: the entire process is natural, but you need to add worms to your garden. You can even make your own worm farm. You can purchase high-quality mixed worm castings and put them in your potted plants. Even though worm casting is not ideal for potted plants, it is one of the best options to keep the soil in perfect condition.

About Chicken Manure

Chicken manure is another excellent organic fertilizer, and most people might think it is readily available. However, it is not as easy as it sounds. There are two ways to get your hands on chicken manure—by keeping chickens, or by buying it directly from chicken farmers in your area.

Chicken manure is not an ideal option for fertilizing garden soil because it smells pretty bad and requires a lot of patience. That said, manure is less costly and works to fertilize larger areas.

Features of Chicken Manure

Acts as a Soil Amendment:Chicken manure releases slowly into the soil and is a valuable macro and micro nutrition source. This makes all the organic matter in the ground perfect for all crops and plants.

Food Source for Soil Microbes: This unique factor is only available in chicken manure. It acts as the best food source to create beneficial soil microbes, increase soil diversity, and accelerate nutrition breakdown into multiple forms readily available for plants.

Organic Material: Since you will get the product directly from the animal itself, there are no chemicals involved in this process. However, chicken manure works best when it is dry-aged and composted.


  • Enhances soil concentration
  • The best fertilizer for tomato plants
  • A rich source of nutrients


  • Loss of nutrients in plants after application

Similarities Between Worm Castings and Chicken Manure

Despite being excellent organic fertilizers, they have a few other similarities too.

Organic Fertilizers:Both are natural fertilizers without additional chemicals to boost plant growth. Since earthworms live under the ground, chicken waste comes directly from chickens, making them chemical-free.

Easily Available: They both are readily available, and you can easily find earthworms crawling in your garden without having to dig too deep. You can even enlist the help of your kids to help dig them out.

Non-Toxic for Plants: Both are non-toxic for typical plants, and they are excellent for fertilizing vegetable plants if used as directed. For example, raw and fresh manure can burn plants, so it is better to use it when dried. If drying fresh manure first is not a viable option, worm castings are more suitable.

Differences Between Worm Castings vs. Chicken Manure

Cost: The difference in price between worm casting and chicken manure is significant. Ten pounds of manure will cost around $30, while ten pounds of worm casting costs around $10.

Storage: Not everyone wants a pile of stinking manure in their backyards, and therefore some people find worms to be a more favorable option. 

More Nutrients: Manure is long known to provide more nutrition for plants and crops, so if you have no trouble handling manure, it is the better option for healthy plant growth.


These two organic fertilizers are an ideal option for garden plants. However, when debating worm castings vs. chicken manure, we believe worm castings to be the sure-fire choice. Worms do not require additional space or effort. Moreover, they are beneficial for enriching plants with more vitamins and minerals. Another bonus is that you can use worms as a continuous source if you manage to keep them alive long enough, which means more organic waste for fertilizing your garden.
