Compost vs. Mulch

Posted on October 12, 2020 at 7:36 AM by Natalie Nebilak


If you cook at home, chances are your kitchen scraps add up fairly quickly. The ends of an onion, the skin of a kiwi, and even coffee grounds. All of these are organic materials that tend to end up in the landfill. However, these odds and ends amassed from the adventures of cooking still have tremendous value to them, even if they don't end up on our plates. Scraps such as these can be collected and transformed into rich and nutrient dense compost. 


Compost is organic matter (such as kitchen scraps and yard waste) that have decomposed via the process of composting -adding organic matter and water to a pile and allowing time and proper aeration to transform the organic material into a nitrogen and carbon rich slurry.

 is full of nutrients that we want to get down into the soil to feed the plants through their roots. Soils can often become depleted of nutrients through over-gardening and use of harmful fertilizers. Adding compost to the soil is a way to replace what has been lost. 


In contrast, mulch is a layer of organic material (usually bark chips or something similar) placed on top of the soil as a protective cover. Mulch helps to suppress weed germination, retain moisture, insulate the soil, and reduce erosion. Mulch is a great way to slow water evaporation from the soil, ultimately conserving more water. A great benefit to our water-wise community!
