Homeowners and horticulturalists may be worried about their trees after this year's long flood.
Michelle O'Neill reports.

Jeff Jensen works for the nonprofit group, Trees Forever. And he's the President of the Iowa Nut Growers Association. He says trees and their roots need oxygen.
But many in Iowa have been under water for weeks and even months. And submerged foliage may die off. A prolong flood is likely to cause trees to be susceptible to pests, fungus, or molds.
Since the soil has been saturated for so long, Jensen says trees can become very unstable and prone to leaning or even falling over.
If a tree shows signs of stress, he says don't just cut it down. Wait and see what happens.
A wide range of factors affect whether A tree will survive a long flood. It depends on the species, length of time under water, and whether the tree was dormant during the flood. Click here for a homeowners guide to taking care of trees after a flood.
