How to Water
Deep water in the early morning when the air is cool. Deep watering allows water soak into the ground through the soil profile where roots reside. Keep in mind that Idaho has lots of clay in its soil profile. Clay soils are slow to absorb and give up water, meaning this type of soil can stay wet for a long period of time, but it also takes a long time for water to move down into the roots.
Newly planted trees and shrubs need consistent and frequent water.
How Much Water?
A 2-3” layer of mulch conserves soil moisture and prevents evaporation on hot days. Mulch also limits temperature fluctuations in the soil. When Idaho hits those hundred-degree temperatures, the last thing you want is to leave your plants ill prepared for survival. Take the extra step to spread a layer of bark mulch in your garden beds, it’s not only worth the aid in water retention, but it gives the landscape a nice facelift.
