Utah’s snow-pack levels are at 46% below average for this time of year, meaning the runoff that fills the streams and reservoirs will be much lower than normal. Combined with higher than average temperatures, there is a temptation to water our trees excessively to make up for the lack of precipitation over the winter.
Such a practice may not yet be necessary and can even be damaging to certain types of trees. Conservation is a very important practice to save water and money…and to keep our trees healthy.

Here are a few tips on irrigating trees in Utah this spring:

1. Over-watering can cause the leaves to drop or turn brown due to suffocation of a root system. Avoid the temptation to overwater.

2. Avoid light, frequent irrigation. Trees need water to penetrate 18-20”. This requires a very slow, steady stream for several hours, rather than lawn sprinklers when irrigation is necessary.

3. When you are ready to plant, look for native trees or trees adapted to arid/semi-arid climates. Trees such as the Rocky Mountain Juniper, Austrian Pines, and Colorado Blue Spruces are among some varieties that do not generally need a lot of additional irrigation.

With proper management you can have green landscapes without using excessive water. This will save money and resources for you and the community.
