How deep should I water my plants?
The 1-2-3 Rule is an easy way to remember how deep to water:
- Water small plants such as annuals to a depth of 1 foot.
- Water medium plants such as shrubs to a depth of 2 feet.
- Water large plants such as trees to a depth of 3 feet.
A good way to test how deep you have watered is to use a soil probe such as a sharpened piece of rebar or a very long screwdriver. About an hour after watering, push the probe into the soil. It will slide easily through wet soil but will be difficult or impossible to push through dry soil. Water your plants and lawn until you can easily slide the probe to the recommended depth.
