Choose Your Compost Starter

Getting microbes to actively break down the mix of materials you use to build compost takes some time. However, adding a compost starter can make your composting activity quite lively without relying on worms. Activating your compost pile, whether it is inside a tumbler, outdoors, or an indoor bin will help create compost faster.

When seeking out a quality compost starter, check the amount and balance of nitrogen, carbon, and hungry microbes. Many compost starters are either liquid or dry and contain fungi, are pH balanced, and include helpful bacteria to help break down materials.

There are a few key moments when you may want to add a compost starter, activator, or accelerator to your tumbler. Remember, you can control how many green or brown items you throw in, adding either nitrogen or carbon. You can also adjust the amount of oxygen and water levels.

However, a compost starter can prove useful for the following:

  • Your compost lacks sufficient carbon or nitrogen materials.
  • You desire more microbiological activity and need hungry microbes to help break down compost faster.
  • The compost is on the drier side and could use more moisture.
  • You want to encourage a healthier pH balance to support fungi and microbes to break down the compost.

It’s perfectly fine to take the long road with your compost and forego using a starter. However, starters make composting a breeze, so why not use one?

Compost starter isn’t absolutely necessary, but it is nice to have around if you are having trouble. It is possible to create a good quality compost if you can achieve a balanced mix of nitrogen, carbon, and moisture. However, your compost will take some time to break down and attract microbes, fungi, and strike a balanced pH.

You can get your compost off to a good start by adding some starter which helps ensure a better mix of green and brown ingredients. Plus, many starters are formulated to support faster decomposition of your food scraps, plant waste, and help you develop nutritious humus for plants in less time than going it alone.

What Does Compost Starter Include?

Commercial compost starters available to gardeners often include a healthy, balanced mix of nitrogen, carbon, and microorganisms, including fungi. Also, compost starters may be in liquid or dried form to best mix with your compost pile.

However, you can create a compost starter using a ratio of 4 carbon-based brown materials to every 1 nitrogen-based green material. Adding a starter with sufficient levels of fungi, bacteria, and organic components helps to speed up the composting process.

Remember, even with the addition of a compost starter it is vital to aerate the compost, keep it moist, and adjust the pH level to encourage healthy microbial activity.

How Much Compost Starter To Use?

You will want to read the manufacturer’s suggestions on how much starter to add to your compost bin, tumbler, or pile for best results. However, some brands call for 1 to 2 cups of starter for every 16 square feet of layered compost materials.

Keep in mind, some compost starters are liquid, while others may be similar to potting soil or a pellet that needs to be dissolved. Follow the provided instructions and use enough starter to get the job done. Piling on too much starter, without consideration to aeration, water levels, and the mix of green and brown materials, won’t help much.

What Not To Put In A Compost Tumbler?

If you want to reduce maggots or noxious odors emanating from your compost, there are some things you should avoid adding to it in the first place. Here is a handy list of items not to add to your compost tumbler because it will thwart quality results.

  • Meat or fish products
  • Pet or human waste
  • Dairy products
  • Cooking oil
  • Bread
  • Sawdust
  • Chemically treated labels, papers, etc.

Certain items will create foul odors, attract more flies, maggots, and create unwanted bacteria in your pile. Stick to adding helpful items to your compost, such as dry grass clippings, vegetable scraps, shredded paper, teabags, and dead leaves instead. Worms, fungi, and helpful microbes will assist with speeding up the composting process.
