Many trees are starting to yellow, especially on top.
 On hot summer days they need water too.  Leaves on many trees are starting to yellow and scorch because they are water-stressed.  Manager at Oakridge Greenhouse, Erna Wiebe, says many trees are starting to yellow especially on the tops.  Poplars in particular are going to lose their leaves much earlier this year.  Wiebe tells us in the past couple years the trees haven't needed to extend their roots because there's been so much rain.  She adds as long as the trees are mature, there shouldn't be any permanent damage.
