When to start using yard rainbird

Asked April 29, 2019, 6:49 PM EDT

We have sprinkling and drip rainbird in ground irrigation. Is there a timeline to begin watering. Also how long should I set the drip lines for decorative trees an shrubs?

Thank you for your question. Before you turn on the spigot, spend ~$10 to buy a soil water probe. There is no ‘one size fits all’ when it comes to watering (or fertilizing, for that matter). Having a simple probe lets you know whether the soil is dry or not. And you don’t need to use your finger. Similarly, some ‘decorative trees and shrubs’ need more water than others, especially during droughts. High water: rhododendrons, azaleas, Japanese maples and hydrangeas. Low water: plants—especially trees with taproots—since the tap root taps into underground water supplies. And all of these plants use more water if they are planted in full sun, have no mulch, or are competing with closely-planted plants. That’s how the probe helps. But it also assumes that high-water plants are grouped with others like them, etc. Are you able to share what ornamentals you have? Happy to supply more specific information with some detail. There are guidelines, but I’d prefer to focus on your garden. Thanks!

Thank you, very helpful. Will get a soil moisture meter tomorrow.
