Do's and Don'ts of Composting

Many beginning gardeners believe that all you need to grow healthy plants and vegetables is water and sunlight. However, plants also need healthy soil rich in nutrients to be able to grow properly. And composting is a great way to do just that.

But before you start composting, there are a few things to keep in mind. Like what can and cannot be composted:

The IN List:

  • Animal (cow or horse) manure 
  • Cardboard rolls 
  • Clean paper 
  • Coffee grounds and filters 
  • Cotton rags

  • Eggshells
  • Fireplace ashes
  • Fruits and vegetables

  • Houseplants 
  • Leaves
  • Nutshells 
  • Sawdust 
  • Shredded newspaper 
  • Tea bags 
  • Wood chips 
  • Wool rags

The OUT List:

  • Black walnut tree leaves or twigs. They release substances that might be harmful to plants.
  • Coal or charcoal ash. May contain substances harmful to plants.
  • Dairy products (e.g., butter, milk, sour cream, yogurt) and eggs. Can create odor problems and attract pests such as rodents and flies.
