Use Coffee Grounds to Combat Garden Low Acidity
If your soil is too alkaline (not acidic enough), you’ll have growing much of anything.
To combat low soil acidity, try stirring used coffee grounds into it. You can test the soil originally by either getting a low-cost test kit at your local garden center, or try calling your nearest agricultural school or your state’s department of agriculture. Many of these types of schools or agencies will test soil ph for free.
