What "ph" means in gardening

pH is a measure of the acidity or alkalinity of the soil. It is a numerical scale that ranges from 0 to 14, where a pH of 7 is considered neutral. A pH below 7 is acidic, while a pH above 7 is alkaline. Most plants prefer a slightly acidic soil with a pH range between 6.0 and 7.5. The pH level can affect the availability of nutrients in the soil and the growth and development of plants.
