Plants like pH levels in their water to be between 5.5 - 6.5 because this is the optimal pH range when plant roots can best absorb nutrients. Having a pH pen allows you to take easy pH measurements. Simply dip the tip of the pen in water and receive a reading within seconds. Take note that pH levels can and do change over time - one way you'll notice this is the yellowing of leaves. This indicates that your plant roots are having a hard time absorbing nutrients. Keep your plants healthy by monitoring changes in pH levels before your plants are affected. Don't wait until your leaves turn yellow. Checking your pH levels weekly is a good way to proactively care for your plants.
