Many plants that thrive in Acidic Soils are plants that are commonly found near or under evergreen trees. Plants such as hydrangeas, azaleas, rhododendrons, and camellias.
Some gardens have acidic soil in which some plants will thrive and others struggle to survive. Acidic loving plants that are planted in an alkaline garden will show signs of distress. Their leaves or needles may turn a yellow-green hue. When this happens, the soil is too alkaline. Plants with this condition are said to be chlorotic. This is a result of the plant’s inability to obtain nutrients from the soil due to the soil high pH level. If the condition continues, plants may lose leaves, branches, and its flowers.
The above chart by Garden Tutor indicates the soil pH level for various plants. A soil with a pH balance of 7 is neutral. Slightly acidic soils range from 5.5 to 7. Alkaline soils are above a pH of 7.
