hi is there any reason i shouldn't put perlite into my small compost bucket? there is perlite mixed into the soil i use, and i'd like to add this soil to the compost. i also have a bag of "organic tomato and vegetable" food which i don't plan on using in my garden. could i add a cup full of this to my compost for a little extra nutrients, or am i way off? the compost is going to be mixed with fresh soil when the time comes. thanks!!

RE: perlite in compost bin?

Perlite is a mineral so adding that to compost will do little of any benefit or be of much detriment. It will just be there like sand or clay soil particles.
Adding that "organic tomato and vegetable" food may be of some help depending on the total amount of Nitrogen in the mix. Keep in mind that too much N can be as much trouble as too little.

Agreed, the perlite will not hurt anything and will end up in your soil looking exactly the same.

Fertilizers can be very powerful, and if your 'small compost bucket' is really that small, a cupful of fertilizer may be too much. You'll want to add some browns to offset the N content. Using fertilizer is actually a way to get browns to compost faster if one is short on greens, although it's an expensive method if you're buying fertilizer for that purpose. If you're just getting rid of leftover fertilizer, just use some browns and watch for odors and other signs of high N.
