Things to Consider When Choosing the Best Compost Starter for 2023
There are many things you need to keep in mind when shopping for the best compost starter. Here are a few things we thought of while creating our list.
How to Use a Compost Starter
Typically, compost accelerators can be added directly to your existing compost contained in a bin, tin, or another storage container, in order to help move the composting process along more quickly.
In most cases, you can simply mix the compost accelerator into a blend of soil and organic waste material or pure waste material and let it do its work. Within 4 to 6 weeks, the starter will have helped break down the organic matter more quickly and enriched the soil.
However, directions on compost accelerators may vary slightly, so it is always considered best practice to review the packaging on the starter of your choice and follow any instructions provided.
Things To Always Have in a Compost Starter
When selecting the best compost accelerator for your needs, you should generally keep an eye out for a few specific qualities. In general, you want a starter that has as much organic material and as few artificial or chemical compounds as possible.
Also, the more microorganisms and microbes present, the better! Having these as part of your compost accelerator helps cut the time you would typically need for your base compost to develop them slowly over time.
How Much Time You Have to Kickstart Your Compost
There are no two ways about it…compost takes time to break down. This is true whether you use a compost accelerator or not. The starter certainly helps to speed up the process, but even our pick for the best starter on a time crunch will take time to do its work.
When you are choosing your compost accelerator, try to plan in advance how much time you will allow for your compost to mature before you lay it down in the garden. If possible, give yourself more time as opposed to less.
You can always rotate and continue to add to your compost bin, keeping it going as long as necessary, so there is really very little risk of starting it “too soon”. However, you don’t want to start too late and end up with compost you can’t use because it hasn’t broken down fully yet.
Compost Starter FAQ
Should I Always Use a Compost Starter Or Accelerator?
While it may seem like a fast-acting starter would always be useful to give you a quick turnaround, there are some cases where using a compost accelerator may be unnecessary or even counterproductive.
In general, if you are working with a compost bin or heap that is already well-established, easily rotated, and rich in nitrogen, as well as regularly watered and with access to good air circulation, a compost accelerator is not going to add many benefits to the mix.
However, these starters are ideal, especially for indoor compost bins. These tend to be dryer, have less airflow and fewer natural microbes, and are less nitrogen-rich than their larger outdoor compost heap counterparts.
In these cases, a good compost accelerator like those on our list can really swoop in and save the day!
What Else Can I Do To Maximize My Compost and Starter?
A starter is an incredibly valuable tool for helping get your compost in good shape quickly, but it’s not the only asset in your arsenal!
You can also really help your compost thrive, starter and all, by having worms in your compost mix. Worms and their waste help strengthen soil health with natural fertilization, which can help make your compost overall, and your compost accelerator more effective.
You will also want to focus on adding things to your compost that break down quickly and easily. This will help your compost starter work at its optimal speed and efficiency. Things like eggshells, coffee grounds, and leafy greens tend to do especially well.
It’s also helpful to get in the habit of chopping or shredding your compost components before you add them in. These smaller, even shredded pieces are much easier for the microbes to break down in a short span of time.
