Water: Too Much or Too Little of a Good Thing

A tip for watering your lawn:

You can measure your irrigation with an empty tuna can. When the water reaches the top of the can you have irrigated with one inch of water in that spot. Deep, thorough irrigations are preferable to repeated shallow waterings ( typically 1 to 3 times a week). One inch of water a week will typically suffice (two inches as an absolute maximum).

Over watering will cause you more problems than it will solve. Over watering directly leads to fungal disease and poor root systems. Much of the water from short watering cycles never even reaches the roots, and, if it does, it will only have penetrated the soil profile within an inch of the surface, eventually pruning the roots of the plant.

Types of soil and existing root depth will also help to dictate your watering needs. Sandier soils will require more watering because of poor moisture retention. Clay soils or poorly drained soils will require shorter periods of irrigation. Poor root systems may require more frequent, shorter periods of irrigation.

An examination of your existing soil conditions and root depth are essential for determining your exact watering needs.
