Ericaceous compost is acidic in nature and a good choice for acid-loving plants like azaleas and blueberries. While some acidic soil is tolerable, this particular compost may not be suitable for use on oinions as they are sensitive to overly acidic soils, growing best when the pH is between 6.2 and 6.8.
