Can you mix sand with compost?

Yes, you can make a great potting soil mix by combining sand and compost — as long as you use the proper sand and mix the two ingredients correctly. First, make sure that the compost you are using is completely broken down by running it through a mesh screen to filter out large pieces that need to be returned to the compost pile to continue breaking down. Only use the smaller compost particles that pass through the screen, as these particles have broken down successfully and are ready for use.

Can you put citrus in compost?

Yes, putting citrus fruit into your compost has many benefits, as long as you balance the acidity in your compost pile to counter the acidity boost that citrus will bring to the pH balance of your pile. Also, if you are vermicomposting, you may want to avoid adding citrus fruits altogether, as certain worms prefer not to eat citrus, which can slow down the decomposition process in worm compost bins, but in regular composting systems, adding citrus fruit and peels is perfectly safe and has several benefits.

Can you put coffee grounds in compost?

Yes you can, in fact, the safest way to use coffee grounds in the garden is by adding them to your compost pile. However, if you drink a lot of coffee, you will want to watch how much you add to your pile, as coffee grounds should only make up 10 to 20 percent of your total compost volume. If more than 20 percent of your compost is made up of coffee grounds, it might inhibit the beneficial microbes from breaking down organic matter effectively.

Can you put leftover food in compost?

Some of your leftover food can be added to compost, but there are some things that you’re better off repurposing in a stew or simply throwing out with the trash. Leftover fruit and vegetables, whether raw or cooked, can always be used in compost. You can compost fruits and vegetables even when they’ve spoiled and gotten moldy. (Consider it a head start on the decomposition of the compost heap.) The peels and trimmings from your fruit and vegetables are also fair game for adding to the compost bin.

Can you put onions in compost?
