Buyer’s Guide – Making The Selection Of The Best Garden Compost Tumbler
Are you confused about what compost tumbler features to look for to meet your garden requirements?
In this buyer’s guide, we have outlined some of the main factors to consider to help you make the best purchase from among the above-reviewed composters.
1. Your Composting Plan
Your specific composting plan could be to add garden waste and kitchen scraps regularly.
Conversely, your plan could be to process a one-time compost batch.
Determining your composting plans can help you decide if a dual-chamber composter is more suitable than a single chamber barrel.
If you plan to compost the waste material regularly, you should go for a dual-chamber tumbling composter so that you can fill the second chamber when the first one is composting.
The advantage of single-chamber composters is that they don’t use much space and generally have a larger capacity.
Also, if you have the need to collect liquid fertilizers, then you should consider that some composters let you collect the compost tea (the dripping liquid compost).
Liquid compost is desired for its precious nutrient-rich value that helps plants grow and flourish faster and healthier.
2. Effortless Functionality
When choosing the best compost tumbler, you should ensure it features ample aeration to remove unwanted strain from the mixture.
Proper aeration built into the tumbling composter design ensures you won’t have to do the hard work of regularly using a rake to eliminate the air.
Also, look for an easy rotating tumbler so that you don’t have to lift to unload the heavy composter putting a strain on your back.
Rotation is required not just for easy unloading, but also to give the contents inside the tumbler the necessary periodic mix for faster processing.
Your best option would be composters that rest on a frame that is raised significantly above the ground.
This way you don’t have to kneel down and do the loading, unloading, and rotating of the bin.
Other things like a sturdy locking mechanism also help deter issues like the waste leaking back out or rodents and pests entering the tumbler bin.
The best compost tumblers come in various shapes and sizes.
The shape is an important factor and variants include rectangular, square-shaped, and round bins.
Ideally, round bins or barrel-shaped tumblers should be your preferred choice.
They (round bins & barrel-shaped tumblers) tumble easily and because of their roundness, there’s no chance of cold corners and accumulation of stalled decomposition.
4. BPA & Rust Free
While selecting the best compost tumblers, a BPA Free compost bin is definitely to your advantage.
BPA Free means the compost tumbler’s material composition does not contain organic compound Bisphenol A that is commonly used for industrial usage. BPA is a chemical that hardens PP and makes epoxy resin.
5. Made In The USA
Preferring an American made compost tumbler isn’t only for patriotic reasons. Though that sounds great!
It’s a fact that made in USA tumblers ensure your final compost isn’t polluted with a chemical compound.
The United States has the toughest regulations in place when it comes to plastic products.
1. Should worms be put inside the compost tumbler?
Compost tumblers retain heat to help bake the materials faster.
It becomes optional then whether you want to add worms or not.
Gardeners who wish to add worms are recommended to go for Red wigglers, as they have a higher resistance to the hot temperatures inside the tumbler.
Red Wigglers are also the right choice because they have big appetites and break down organic material accordingly.
The only words of caution are to not put too many red wigglers inside together in one batch.
2. How often should the compost tumbler be turned?
It is recommended you turn the compost tumbler 4 to 5 times per week.
3. How long does it take to make compost in a tumbler?
It takes between 20 to 30 days to make compost in hotter regions as the decomposition process happens faster in warmer areas.
In cold and rainy weather, the compost becomes damp, requiring a longer time to break down.
It can take 2 to 3 months to make compost in snowy and rainy weather, but this time can be reduced slightly if a compost starter is added.
4. What are the compostable waste materials you can put inside a tumbler?
Only the right types of waste materials will decompose fast and not cause any issues.
Here’s a list of the right types of things to compost that are natural waste materials that don’t give off a foul smell :
● Fruit & vegetable leftovers (including peels)
● Dead and fallen leaves
● Grass clippings
● Plant prunings
Further, recyclable waste that breaks down easily includes:
● Damp paper waste
● Cardboard egg boxes
Animal waste that accelerates nitrogen inside the waste pile inside your tumbler:
● Cow and horse dung
5. What materials should not be put inside a compost tumbler?
Avoid adding the following in your compost tumbler bin:
● Dog & Cat poop
● Plastic coated paper & plastic in general
● Meat scraps & Fish leftovers
● Sticky paper labels found on fruits & vegetables
● Thick tree branches
● Onions and onion peels
● Coal and ash
6. Do compost bins smell bad?
If the bin is filled with the right types of waste, there is no reason for it to smell bad.
The normal or typical smell you can expect is similar to the smell of dirt.
Lack of heat and ventilation can lead to a slowing down of the decomposition process and result in a foul smell.
Composting helps plants flourish as they are fed the compost end-product – a natural nutrient-rich fertilizer.
It also serves as a protective measure for the wellbeing of the environment.
If more people start composting in their backyards or balconies, the burden of landfills will fall dramatically.
The above list of the top 6 garden compost tumbler bins along with the detailed buying guide and FAQs would help you in choosing the perfect composter to meet your specific needs.
