An article I recently read explains that the early spring and dry summer experienced in many parts of Canada this year may impact the display of fall colours.
Chlorophyll gives leaves their green colour. In fall when day length gets shorter and overnight temperatures get cooler, trees stop replacing chlorophyll which allows other pigments, including the ones responsible for the beautiful oranges and reds, to become visible.
But, according to this article, the early spring and dry summer may cause leaves to change colour earlier this year and they be not be so colourful.
How are the colours in your area? I’m seeing beautiful fall colours and can’t wait to get out and explore some nature trails this long week-end!
