Compost Ingredients

Asked May 5, 2020, 6:02 PM EDT

Is it safe to use grass cuttings from a lawn that has been fertilized by True Green Lawn Care as the "nitrogen" additive in making a compost pile?

Green plant material in general contains a high percentage of nitrogen. Table/fruit/vegetable scraps, grass clippings, lawn & garden weeds, coffee grounds, garden waste, leaves, etc. are nitrogen-rich components in compost.

If there are additional chemicals such as weed killers and other pesticides used on the lawn, please note the following CSU Fact Sheet on thorough breakdown of these chemicals.

Most importantly, it is better to leave grass clippings on the lawn to put the nitrogen back into the soil. The lawn needs the nitrogen more than the compost pile.
