Trees getting wet during Grass Sprinkler watering

Question

HI,

I have an in ground sprinkler system for my lawn that runs about 45 min 3X per week.
In a few locations there are very large mature trees (Oak, Maple) who’s bark/Base gets wet during the watering process.
Because many are in the shade, moss has been growing on these trees. The look doesn’t bother me, but i’m concerned that the tree shouldn’t rot or get any diseases. Can you please assist?

Thanks!

Sam

Answer 1

Tree trunks don’t absorb water for the purpose of growth.
Water droplets often serve as vehicles to carry bacteria to your tree.
The water that does fall to the ground around the tree is too close and does not benefit the water-absorbing roots closer to the outside of the canopy.
Place or direct sprinklers or irrigation systems to avoid tree trunks.
If you can’t avoid the tree trunk, adjust the spray to spare as much of the tree trunk as possible.
If you want to water your tree, place the sprinkler half way between the trunk and the edge of the canopy and remember tree roots need to be watered longer than any other plant in your yard.
