In this KPRC 2 article, Matt Petty from Davey’s South Houston office talks about the signs of a tree suffering from drought.
The devastating 2011 drought left 301million trees dead across Texas, 10% of the total.
And while drought can certainly increase tree problems of insects and disease, the real bottom line is that trees need water. And right now, most of them aren’t getting enough. Water allows trees to transport nutrients from their roots to their leaves. Almost all of the water moving through a tree is used to keep stomata open, which are the pores that let in carbon dioxide, allowing a tree to carry out photosynthesis. Without water, hydraulic failure occurs and trees have to depend on stored sugars and starches and they’ll run out if the drought continues long enough.
