What does coffee grounds do for soil

An oft-repeated nugget of advice is to spread used coffee grounds around plants that are vulnerable to slug damage. There are two theories why: either the texture of the grounds is abrasive, and soft-bodied slugs prefer not to cross them, or the caffeine is harmful to slugs so they tend to avoid it.

However in an experiment slugs took just seconds to decide to cross a barrier of coffee grounds! One word of warning though: coffee grounds may not have much effect on pests, but they can be harmful to pets in large enough doses. But if you have a dog that insists on sampling anything that smells halfway agreeable, it would be wise to avoid laying coffee grounds directly onto the garden. Bury them in your compost heap instead. Coffee grounds are free organic matter, whether a by-product of your at-home daily brew or collected from coffee shops that are only too glad to give them away for nothing.

Another plus? Worms like coffee grounds and worms are a necessary part of the ecosystem that is any garden. Composting can be very beneficial. There are two types of compost material: green and brown.

Coffee grounds fall into the green category since they are a green material, which means they are rich in nitrogen. Coffee grounds typically have about 1.

Other green materials are food scraps and grass clippings. All of these green materials contain magnesium, calcium, potassium, and other trace minerals. You can throw your coffee grounds, paper filter and all, into your green compost bin, but when it comes time to put the compost in the garden, you must mix your green compost with some brown compost. Brown compost material consists of items such as newspapers and dried leaves. The general rule is to have a 4-to-1 ratio of brown to green compost material.

This residue can damage certain vegetable, fruit and flower crops. The residue likely comes from contaminated hay, grass clippings or manure.
