DES MOINES– As drought conditions continue, Iowans are concerned about the amount of water their yard trees need. Drought conditions can lead to tree decline, pest problems and, in extreme cases, tree mortality. Supplemental watering for mature trees will help maintain tree health during drought.
The best way to provide supplemental water to trees during a drought is manually. A bucket to measure how many gallons is best, but a garden hose, moved often, can provide a good soil soaking. Sprinklers are less efficient.
