TreeUtah encourages you to be water aware, and understand how to care for your trees year round!
Since summers in Utah’s valleys are hot and dry, it is
important to make sure your trees are getting
enough water. Due to differing elevations, microclimates, and tree species, it is not possible to recommend an exact amount of water that any given tree needs, but follow the guidelines below to be sure your trees have the water they need.
Infrequent, deep watering is more beneficial than frequent, shallow watering. Established trees should be watered 1-2 times per week to a depth of 2-4.” Deep watering ensures that the tree roots grow deeper in the soil, which allows them to be more drought-tolerant later in the tree’s life.
How to Check if Trees Need Water
Over-watering a tree can be just as harmful as under-watering, so be sure to check before watering. Use a garden trowel or even your hand to create a small, narrow trench near the trunk of the tree. The trench should be 2-4″ deep. If the soil is moist to the touch, the tree doesn’t need water. If the soil is dry, give the tree water.
Watering Newly Planted and Non-Established Trees
The first 2 years of a tree’s life is critical for survival. The tree is establishing it’s root system in the soil and is sensitive to stressors like heat and drought. Water a newly planted tree immediately after planting and routinely check the soil moisture often to be sure the tree has enough water for the next 2 growing seasons. After the tree is established, it will have an easier time adjusting to heat and drought conditions.
Another easy way to be sure your tree has enough water is to use a gator bag. This is a zip-up bag that goes around the trunk of the young tree. Fill the bag with water and it will slowly drip out of the bag to water the tree. The bag will need to be filled about once every 5-7 days.
