How to build the perfect apartment composting system

If you’re looking for a way to reduce your food waste and nourish your plants, then composting is one amazing option to do just that. Composting has a certain image, though — large bins or piles outdoors that have to be turned with pitchforks and spread with shovels. What if you don’t have the space for that? Wonder no more; we’re going to walk you through how you can compost in an apartment and why you should.

How much space do you need to compost?

The answer to this question depends on how much compost you want. Larger gardens will need more compost to fully cover, while smaller gardens and container gardens will need less. It’s also important to consider how much you’ll be adding to your compost. If you produce a lot of scraps by cooking meals of mostly fresh produce for an entire family, you’ll need a bigger bin. However, if you’re only producing a few scraps, such as just cooking for one or two, you’ll need much less space.

This is good news if you live in an apartment. Most likely you’ll be producing fewer scraps and have a smaller garden or container garden to feed. A space that is a square foot or two at the base and another two or three feet tall will be big enough. An unused cabinet works great, but you can also tuck your bin into a corner, stack it onto something else, or make use of a balcony space if available.

Set up a system that works for you

The basic compost bin is a container of the preferred size with holes in the top, sides, and bottom for air flow and excess water evaporation and drainage. If you’re keeping your bin indoors, you can double the amount of air flow holes in the sides and top and forgo the bottom holes. Or, set your bin in or just above some type of tray to catch water as it drains so you can dispose of it later. Your holes don’t need to be very large, just half an inch will do.

Depending on your preferences and needs, you have a few more options. Some people keep a second, smaller bucket in their kitchen for collecting scraps. This allows you to keep your bin tucked away, reduces your trips to the bin, and can help keep your bin balanced.

Using your compost bin

Start your compost off with as close to even as possible a mix of brown material and green material. Brown material is dried organic material like newspaper, paper, straw, hay, and dried leaves. Green material is fresh organic material like fruit peels, vegetable scraps, and grass clippings. You can also add some soil to jump start your compost. If you use potting soil, try to get some without any fertilizer already mixed in.

Whenever you add anything to your compost, stir or mix it well to add in air. You can mix it with a shovel or sturdy stick. Another option is to secure a lid or covering over the top, turn it on its side, and roll it back and forth for a couple minutes. If you’re doing this indoors, you may want to lay an old sheet, drop cloth, or blanket in case there are spills. Keeping your compost loose is crucial for even decomposition and to keep it from smelling. If your compost begins to smell, it likely needs more air flow or has an imbalance of brown vs. green material.

What are the benefits of composting?

Compost contains all the nutrients that rich soil naturally has and is as organic as the scraps you put into it. This is great for indoor plants since their soil isn’t being replenished over time the way it would in the wild. Since you know what has gone into it, it also gives you total control and peace of mind over how organic your plants actually are.

Composting also has environmental benefits. According to the United States Environmental Protection Agency, in 2018 alone the United States generated 292.4 million tons of municipal solid waste, which includes food scraps, packaging, broken furniture, and other similar items that commonly end up in landfills. Of that total, they found that roughly 32 percent was composted or recycled, while 50 percent went to the landfill.

A lot of waste comes from corporations, and, unless you’re the CEO of a major company, that may seem like a daunting problem to solve. If you aren’t sure where to start, start at home. Composting in your apartment is a small step, but it is a step. Getting involved in your community and reaching out to encourage others to do their part is a great way to increase that 32 percent — and decrease the 50 percent.

Anyone can compost, whether you have a sprawling yard or a small apartment. Your plants will thank you for the boost in nutrients, especially indoor plants. If you want, you can even tailor your compost to the specific needs of your plants, although a balanced compost will work for just about any plant. Remember to give your compost plenty of air and a balanced diet of brown and green material, and your compost will be just fine.

When you first start gardening, it's overwhelming to think about all the things you have to keep track of to grow healthy and happy plants. For example, one of the most common topics beginner gardeners worry about is buying the best composts for gardens. What type should you use, when should you use it, how much of it should you use, and is there a specific one you should use for particular types of gardening? This can all become intimidating quickly, but we promise that after you read the information below, you'll feel confident in your ability to successfully add compost to your garden soil.

The best types of compost
More often than not, the soil you want to plant your garden in will need to be amended. This simply means you need to add some things to it to make ideal growing conditions for your plants. Almost always, this means adding compost. However, with so many types out there, you might get confused when standing in front of all those bags at the garden center. So what options do you have, and what are they made of?
1. Leaves and yard trimmings
Using the leaves and trimmings from around your yard is one of the best ways to recycle and add vital nutrients to your garden beds. It's low cost, efficient, and moisture retentive. Additionally, these can be used as mulch and compost! Keep in mind, the number of leaves and trimmings available can change from year to year and season to season. So you might have plenty one time but not enough the next. There also may be stray grass or weed seeds that get in there and introduce unwanted plants into your garden. 
2. Manure
If you're lucky enough to have access to fresh manure, you have one of the best resources for a garden. Raw manure adds nitrogen, phosphorous, and potassium to your soil, which are the three most important things to have in healthy soil. You might even have access to manure from your own animals! This is a low-cost and waste-reducing way to add essential ingredients to your soil. You can also buy manure in bags at the garden center if you don't have access to it fresh. This is still fantastic for your garden but less great for your wallet.
3. Mushroom compost
Mushroom compost is typically used for, you guessed it, growing mushrooms. However, you can also use this type of compost in your own garden at home. It often contains materials such as wheat straw, manure, gypsum, peat, cottonseed meal, and grape clippings. It's packed full of nutrients and is a sterile substrate that can enhance water retention while also adding essential elements back into the soil. Unfortunately, this type of compost is more expensive than other options on this list and might be best reserved for those growing mushrooms where sterile fertilizers are essential. 
4. Vermicomposting
You might have heard of worm farming, and vermicomposting is the fancy word for it. This is when you let earthworms decompose organic material. The worms eat, digest, and excrete the material and they produce castings, which are nutrient-dense and all-natural. To get these excellent earthworm castings, you can either start your own earthworm farm or purchase a bag of castings at your local garden center.

You have questions, and we have answers. Here’s everything you need to know about using coffee grounds as fertilizer.

Coffee grounds as fertilizer
Coffee grounds are mainly added to soil due to their high nitrogen content. Nitrogen is a key nutrient involved in plant growth and development. For soils that lack nitrogen, the boost that coffee grounds provide can be very helpful. However, it is a delicate balance. Too much nitrogen can actually stunt their growth.
