GOOD TO GROW: Distressed Trees

Denise & Norma talk with Oscar Mestas, Regional Urban Forester with the Texas A&M Forest Service.  Oscar talks about why our trees often don't respond right away to severe environmental events, such as a hard freeze or an ongoing drought.  Trees often display distress months or even years later, and trees in distress often invite pests and disease.  Aired June 1, 2013.
