Residential Lawn & Garden Irrigation

Last updated: Aug 05 2026

Key takeaways

Water is often the most limiting factor in plant growth and is essential for plant processes and nutrient absorption.

Irrigation should replace water lost from the soil and plants without applying excess water that can waste resources or harm growth.

Effective lawn and garden irrigation depends on soil, plant needs, weather, and applying the correct amount of water at the right time.

Irrigation of lawns and gardens is one of the most important aspects of residential horticulture. Unfortunately, the correct application of water to one’s home landscape is also one of the least understood aspects of home horticulture. Little time is dedicated by homeowners and gardening enthusiasts to learning about irrigation.

It is true that factors like poor soil fertility, improper amounts of sunlight, diseases, insects, and more can limit the production processes of plants and ultimately plant growth. However, water is generally seen as the most limiting factor in plant growth. Not only is it required for many production processes in plants, but it is also necessary for the proper absorption and transport of nutrients in plants.
