pH testing is a crucial practice in gardening to measure the acidity or alkalinity of soil or water. By assessing pH levels, gardeners can ensure optimal growing conditions for their plants, as different plants thrive in specific pH ranges. Whether you're growing vegetables, flowers, or fruits, maintaining the correct pH is essential for nutrient absorption and overall plant health. pH testing kits or meters are handy tools for accurately monitoring and adjusting pH levels, allowing you to cultivate thriving and vibrant gardens.
