Water Quality

The quality of the water you use to irrigate your plants can affect their growth and health in many ways. Water from coastal wells and aquifers can often have high levels of salt, and most plants can handle only small amounts. Some homes have "hard" water, meaning it has a high mineral content, which can clog irrigation systems and leave white, filmy deposits on plants. Water with a high pH can interfere with a plant's ability to absorb iron and other micronutrients.
