Factors To Look For When Buying Best Worm Composter

When looking for a worm composter, you need to be sure that it does the job as it says and will not give you any headaches. You may have the right ideas and great knowledge, but nothing will work if you buy a low-quality composter.

Here are some key aspects to keep in mind when looking for a worm composter:

1. Space Available

Before you even start looking for a worm composter, you should be sure of how and where you plan to keep it. The space is important, and while most people prefer to keep the composter outside, many prefer to keep it inside their home. The design, size, and looks you choose will rely on where you want to place it.

You might need a different setup in case you plan to use the composter inside and make sure that it is climate-controlled so that the worms can produce high-quality compost for your plants. Buy a well-designed and attractive worm composter if you plan to keep it inside. However, just keep in mind that there might be a slight smell that can make your interiors unpleasant.

If you plan to use the composter outdoors, consider the size and shape of the garden. Buy the color and size of the composter accordingly, and it should have some features like little extra rain-shedding and other protection.

2. Quality

Quality is important here, just like any other product. So, pay attention to the material when shopping for a worm composter. Choose a composter made of strong plastic or good quality resin, as these materials can withstand extreme weather conditions such as hot summers or hail or snow.

3. Light And Ventilation

Worms prefer to keep away from sunlight, and therefore the composter you pick should be opaque so that it can block excess light. Ventilation is another key factor to focus on, and therefore, whatever model you buy, check that it has holes running through it for improved ventilation.

Good ventilation ensures that the worms are getting enough air and promote finer compositing. This will stimulate a natural environment for the worms so that they can thrive and do a better job in an environment with the right amount of light and air.

4. Number Of Trays

Added features such as trays enhance the functionality of the worm composters. The best worm composters boast of a higher number of trays for added expandability. While most standard models carry a four-tray size, there are some that are expandable up to eight-trays. That means one can modify the system to their needs and are not limited by fewer trays.

It is well worth investing in a heavy-duty worm composter if you are into composting big time and with a higher number of trays.

5. Drainage

Proper drainage is important, especially if you are using a lot of fruit or vegetable waste and other wet materials. All that waste matter tends to produce a liquid known as leachate and will load the bedding with extra moisture. This is certainly not good for the worms and composting. So, ensure that there is a proper draining method for leachate. There should be an adequate number of drainage holes in the tea collector tray for proper drainage.

If the worm composter has a spigot, one can use it to drain off the leachate regularly. As leachate itself does contain some nutrients, you can mix it with water and use it to nourish the soil in the garden or lawn.

6. Customer Care And Warranty

The best quality worm composters are supported by great customer care and are backed by a warranty that may last from one year to ten years. The kit should include an instructional manual and DVD, so that you can follow the instructions carefully and understand how the unit works. It is a good idea to get a composter with a life time warranty and avoid one with no such cover.

Just keep the above things in mind, and you are sure to get that best worm composter for your garden or for indoor use.

Mistakes To Avoid When Composting

You may have just bought the best worm composter, but things will not work out if you do not know how to use it. Many users end up making some mistakes, and here are some of the most common ones.

1. Overfeeding The Worms

Do not be over-enthusiastic and keep feeding the worms, as they would not be able to keep up. So, feed them just twice a week for the best results.

2. Feeding Wrong Foods

Another common mistake is to feed the worms with processed foods, spicy foods, oily sauces, tomatoes, and more. The ideal diet for the worms would be tiny scraps of non-acidic fruits and vegetables.

3. Too Dry Or Too Wet Composting Bedding

Do not be an over-enthusiastic composter who waters the composting bedding surface every other day, or the negligent one who forgets to check the moisture level. A too dry or too wet environment will kill the worms.

4. Not Removing Finished Compost

Many people tend to forget to harvest the finished compost. Keep in mind that the freshly made compost is the best organic fertilizer for the soil. Mark the days for removing finished compost.

5. Ignoring The Temperature

Too hot or too cold temperature is not good for the composting worms. Location and temperature are important, and therefore one must mitigate those risks with proper care and steps.

So, watch out for the above listed common mistakes and avoid making them.

FAQs

1. How To Get Those Flies Of The Composter?

If you place the food waste too close to the surface, it is likely to attract fruit flies and other insects, and that can be annoying. To get rid of the issue, you should always place the food scraps inserted below the surface of the bedding. Another good idea is to place a sheet of dampened newspaper or cardboard to block those insects and keep the waste safe and protected for the worms.

2. Is It Okay To Have Mold Or Sprouted Seeds In The Worm Composter?

Sprouted seeds are fine and should not be a problem, as you can use them as food for the worms. However, if you see signs of mold, that is an indication of rotting food. It is essential to get rid of black or green entirely and prevent further molds formation by placing the food deeper under the bedding’s surface.

3. Why Are The Worms Trying To Escape From The Composter?

Despite buying the best worm composter, if you find issues like worms trying to escape, then you are doing something which is not right. There could be a few possible reasons behind this, such as the bedding may have become too acidic.

In that case, you must avoid throwing in pineapple scraps or citrus peels and lower the pH level by adding crushed and dried eggshells. Moreover, the bedding should be moist and not dripping with moisture. The right pH level is surely going to keep the worms happy.

4. How To Get The Best Output From Your Worm Composter?

You may not be able to get the worms have everything they need out of your composter if you do not know how to work with it. First of all, you need to be sure that the worms are placed within the middle of the pile of waste. Don’t just pile up the worms on the top. And expect them to find their way within the waste. So, make sure that the waste pile is properly mixed and ventilated, so that the worms can wiggle about.

5. How Many Worms Are Needed?

As a general rule, one would need about 2,000 worms to work on every pound of food waste. Just have some idea about the amount of composting to be done and buy the worms accordingly. They are sold in weights, and 2,000 worms will weigh about two pounds.

You can always start with a small number of worms and gradually raise the volume and number as you gain experience and confidence with your composter.

6. What Are The Top Manufacturers Of Worm Composters?

The leading companies that are known to make the best selling worm composters are Worm Factory, Nature’s Footprint, VermiHut, Quest, Homestead Essentials, Tumbleweed, Generic, Dirt Dynasty, Kahariam Farms, Agrilife, Jialiming, SLO County Worm Farm, and a few more.

These manufacturers know what their customers are looking for and make quality composters with essential features, backed by customer support and warranties.
