The Q&A Archives: Acid Loving Plants

Question: How do you tell what is an acid loving plant and what is not?

Answer: I wish there were an easy way to tell which plants like which kind of soil, but the truth is, you'll have to look up individual plants in a good horticultural encyclopedia to discover their growing requirements. Generally speaking, most cultivated plants are happy in soils with a pH of 6.0 to 7.5. Since 7 is neutral on the pH scale, anything slightly more acidic or slightly more alkaline shouldn't make much difference to most plants. There are some real acid-lovers, such as blueberries, azaleas and rhododendrons, and there are some plants that prefer alkaline soils, such as lilac and cacti. Most areas with high rainfall will have acidic soils and areas with little rainfall will have alkaline soils. That's just a general observation, and your mileage may vary. Hope this answers your question!
