Thursday, September 9th 2021, 5:03 pm - While we're all looking at the leaves, how well do you know your Canadian trees and shrubs?
Over the next few weeks, all eyes will be on Canada's trees as they start to turn bright shades of red, orange, and yellow.
It's a sign of the times -- with fall-like temperatures right around the corner.
Colours typically peak in late September and early October, so get your cameras ready.
WHY DO THE LEAVES CHANGE COLOUR?
"Temperature plays a factor in the coloration of trees, but the most important factor is called the photo period, or the length of daylight," horticulturalist Bob Osbourne of Cornhill, N.B. tells The Weather Network.
"The shortening of the number of hours of daylight is the trigger for trees to start shutting down. A cork-like layer forms between the leaf stem and the branch, which will eventually fall off and it also protects the tree from any kind of fungal or bacterial infection. As it shuts down, it begins to stop water and nutrients from coming into the leaf and the chlorophyll dies."
