What Plants Grow in Acidic Soil?

Most plants grow in slightly acidic soils with a pH below 7, where a typical lawn might be happy. The elements acid-loving plants need from the soil are unavailable in an alkaline environment and the plants will yellow and slowly die. These plants thrive when there is plenty of organic matter in the soil such as you might find in forests. Of course, there are a wide range of plants that grow within the range of pH levels between 6.5 and 5.5, but finding plants that live within the near toxic acid levels around a pH of 5 or less is a little more difficult.
  1. Trees

    • Plant trees in acidic soil, as they will usually grow down below the surface soil where acidity levels are high and get their nutrients from the lower levels of the soil. Choose woody shrubs such as azaleas, rhododendrons and roses for acidic sites.

    Flowers

    • African violets, impatiens, begonias and gardenias are all acid-loving plants that thrive in the pH range around 4.5 to 5.5. Choose bulbs for slightly acidic soil with a pH of around 6 to 6.5; daffodils, tulips, narcissus and iris are a few good choices.

    Vegetables

    • Look for radishes and sweet potatoes to grow in low pH soils around 4.5 to 5; peppers, rhubarb and soybeans for the slightly less acidic range of 5.5 to 6.5; and almost all the rest of popular vegetables in soil that ranges between 6.5 and 7 in pH.

    Fruits

    • Plant fruits in acid soil; many fruits thrive in it, including apple and pear trees, raspberry and blackberry bushes, blueberries, strawberries, cranberries and most of the stone fruits. Check the actual requirements of your plant and compare it with the pH levels of your soil to make a educated selection.
