ROCKFORD (WIFR) -- Many of you have been asking us our Facebook page about, how this heat wave is impacting trees in the Forest City.

We'll we stopped by the Klehm Arboretum to talk with local arborist John Moors. He says if we don't get rain soon many of our trees could be in trouble. Right now, the main thing to look out for is drooping leaves turning yellow or brown. Moors explains why its really important to water our trees slow.

"It probably would be best not to water a tree that's been cited, unless you can water thoroughly. Superficial watering can do more harm than good, again a slow through watering is what we are after," Moors said.

Moors says most trees will need anywhere from 20 to 30 gallons of water and the best way to do that is with a slow drip hose or using a low setting on a sprinkler.

Moors also says newly planted trees four years and younger should be water weekly.
