so any plant that does not like acidity will have problems with coffee. If you have plants, just check to see if they prefer an acid soil or not before you use them.

With that said, I have not had any problems with compost that has coffee grounds in it. It is possible that the composting leeches some of the acid out. I find that grounds are great for working into the soil to give it more texture and it keeps my clay soil looser and easier to work with.

Kolesar, is your soil high or low PH, alkaline or acidic? JDPriestly Mar 2012 #9
