Composting is an easy and enjoyable way to improve your home garden. Not only does it provide natural nutrients for the soil, but it also reduces waste by recycling organic materials. Composting works by breaking down organic matter like food scraps, grass clippings, leaves, and branches into a nutrient-rich fertilizer that can be used to nourish plants and vegetables.

It’s an essential part of sustainable gardening, and it’s simple enough for anyone to do. In this article, I’ll dig into the basics of composting and how you can get started in your own home garden. I’ll also cover some tips on maintaining a successful compost pile and what materials you can add. 

The science of composting

The key to successful composting is creating the right balance of carbon (C) and nitrogen (N). The ideal ratio of C:N for a hot, successful compost pile is between 25:1 and 40:1. For every 35 parts of carbon, you need 1 part of nitrogen. Around two-thirds of your pile should be “brown” or carbon-rich material. Carbon-rich materials include dead leaves, wood chips, and sawdust, while nitrogen-rich (green) materials include food scraps, grass clippings, and manure.

By combining these materials in the right proportions and providing them with adequate moisture (50-60% of total volume) and oxygen (which can be achieved by turning the pile regularly), you’ll create an environment where beneficial microorganisms can break down the organic matter into rich compost.

What you can and cannot compost

Pretty much any organic material can be composted, including kitchen waste such as fruit and vegetable scraps, tea bags, and coffee grounds. You can also add paper products like newspaper, cardboard, and shredded paper (avoid anything with colored ink), grass clippings, leaves, wood chips, or sawdust from untreated wood.

Avoid meats, oils, dairy products, citrus fruits, and pet wastes, as these can attract pests and create a smelly compost pile. You should also refrain from composting any plants with pests or diseases as this may spread to your garden.

How compost is beneficial for your garden

Compost is full of essential nutrients and minerals, making it an ideal fertilizer for your garden. This “black gold” helps improve your soil’s texture by increasing its water-holding capacity, aeration, and nutrient levels. 

Compost also acts as a natural weed killer by preventing weed seeds from germinating in the soil. Plus, it’s environmentally friendly because it reduces the amount of waste going into landfills. Compost is ideal for flower or vegetable gardens. 

How to start a compost pile

If you’re ready to get started with composting, begin by gathering your supplies. You’ll need a location for your compost pile (preferably in full sun), some type of fencing or container to contain it (like a wooden box with no bottom or pre-build container), and the organic materials listed above.

Once you have all of your supplies gathered, add a layer of carbon-rich materials such as dead leaves and twigs. This layer should be at least a few inches thick. Then add a layer of moist materials like food scraps and nitrogen-rich manure like horse manure. Continue adding layers until you run out of organic material.

Finally, add some water to moisten your pile. Make sure the pile is moist but not soggy. As you get more materials, such as food scraps and dead leaves, add them to the pile, alternating between nitrogen-rich and carbon-rich materials. 

Consider covering your pile with a tarp, a piece of wood, or anything you have available to help retain moisture and keep your pile from getting oversaturated by the rain.

Maintaining your compost pile

To ensure that your compost pile breaks down efficiently, it’s important to turn it regularly with a shovel (every few weeks). This helps provide oxygen and can help speed up the process of decomposition. You should also make sure the pile stays moist but not soggy by occasionally adding water when necessary. Lastly, make sure to keep any animals or pests away from your compost pile to prevent contamination.

As you get more organic material, mix it into the pile instead of layering it. This helps mingle the materials together and results in more efficient decomposition.

Potential problems with compost piles

Here are a few common problems you could encounter with your compost pile and how to fix them.

Compost is smelly: This is usually caused by an excess of nitrogen-rich materials. To remedy this, add some carbon-rich material like straw or sawdust to the pile and mix well.

Compost not heating up enough: Hot compost piles are essential for breaking down organic matter quickly. If your pile isn’t getting hot, it’s likely that there isn’t enough nitrogen in the pile or that it’s too dry. Add some nitrogen-rich material like fresh grass clippings and mix it into the pile, then add water to moisten.

Compost is too wet: If your compost pile is soggy, it won’t decompose properly. To remedy this, add some carbon-rich materials (like straw or wood chips) and mix it into the pile. You can also spread out the pile to allow for better airflow.

Weeds are growing in the compost pile: This is usually caused by weed seeds that have been added to the pile. To prevent this, only add weeds from your garden that don’t have any seed heads, and avoid adding yard waste from other sources.

Pests are infecting your compost: This is usually caused by adding meats, oils, and dairy products to the compost pile. To prevent this, only add organic materials like fruits and vegetable scraps, coffee grounds and tea bags. If you don’t cover your pile already, doing so could help keep pests at bay.

When is your compost pile ready?

When your compost pile has broken down enough, it should look dark and crumbly. The material should have a pleasant earthy smell and have no recognizable pieces of organic matter left. You can also use a test kit to make sure the mixture is ready for use in your garden. Once you’re sure that the compost is ready, spread it over your soil and mix it in gently.

Composting is an easy and rewarding way to create nutrient-rich soil for your home garden. With just a few simple steps, you can reduce waste, avoid potentially harmful chemical fertilizers, and improve the health of your soil. It’s a great way to get started on your journey toward sustainable gardening.
