Beyond the Basics: Advanced Techniques for Optimal Composting

Fellow gardening enthusiasts! If you’re like me, you might have dabbled in composting and relished in the satisfaction of turning kitchen scraps into “black gold” for your garden. 

Most gardeners know about browns (carbon) and greens (nitrogen), while achieving the ideal ratio is more nuanced than it might seem. Quality ingredients are a key factor. Dry leaves decompose slowly, while shredded newspaper might be better and is also a great carbon source. Similarly, grass clippings are great for nitrogen, but too much grass can get slimy.

You might be wondering how to take your composting to the next level now you’ve mastered the basics. Let me share some advanced techniques to help you optimize your composting process for more gardening success!

Compost Tea

Have you tried compost tea? While solid finished compost is great, this nutrient-rich liquid fertilizer is an alternative to boost plant growth and improve soil health.

Instructions:  

Put your finished compost in a mesh bag or pillowcase, and immerse it in a bucket of water for 24-48 hours. Aerate and dilute the tea with water. Use this fertilizer to water your plants or as a spray.

Bokashi Composting

A unique method that involves fermenting organic waste instead of decomposition, Bokashi is ideal for composting with kitchen scraps. Especially for those who want to compost meat, dairy, and other kitchen leftovers, this is an excellent alternative to consider. 

Instructions: 

You’ll need Bokashi bran for this method, which contains beneficial microbes. Layer food scraps in a sealed container, and sprinkle the bran between layers. Once your container is full, seal it and let it sit for two to three weeks. Bury the fermented scraps in your garden or add them to your compost pile for further decomposition. This is especially good for turning kitchen waste into rich compost. 

Hot Composting

Consider using the hot composting method if you want your compost to break down faster. This method may require a bit more attention but will reward you with quicker results. You should aim to reach a temperature of 130-160°F (54-71°C).

Instructions: 

Begin with a base of coarse materials like branches or straw for aeration. Add in a mix of about 2:1 green (nitrogen) to brown (carbon) materials. These might include grass clippings, kitchen scraps, leaves, and shredded paper. Once you have a good mix, turn your pile regularly every few days to promote microbial activity and decomposition. 

Vermicomposting

Vermicomposting is one of the most efficient ways to compost, as worms break down organic material quickly and also enrich it with their castings.

Getting Started:

Create a simple bin with drainage holes and shredded newspaper or cardboard inside. Add in kitchen scraps like coffee grounds, vegetable peels, and eggshells. Keep your bin moist but not soggy, and let it work its magic. You’ll be amazed by how quickly the worms transform waste into nutrient-rich compost. 

Layering and Mulch

Yet another way to boost composting is layering and mulching your pile. This method not only helps aerate it efficiently but also helps maintain optimal moisture levels for healthy growth. 

Layering Instructions:

Layer your greens and browns, while incorporating materials like shredded leaves, coffee grounds, and even small twigs in your pile. Finish off with a layer of mulch to lock moisture in and prevent any odors.

Composting is an ongoing process and requires patience. Monitor your pile's moisture levels, temperature, and overall composition on a regular basis. Add water if it gets too dry. If it's too soggy, add more browns. At the same time, you might need to adjust the carbon-nitrogen ratio from time to time. Think of yourself as a garden chemist, refining your process to achieve optimal growing results.

You can supercharge your composting process by following these advanced techniques, not to mention reducing waste as well. Whether you opt for hot composting, compost tea, or vermicomposting, each method offers distinct benefits that can lead you on the path to more successful gardening.
