I was curious about what causes the Fall colour change, so I thought I'd share my internet-based findings with you. As the temperature begins to drop and the days become shorter, chlorophyll production in plants gradually ceases. This means that the green colour usually present in leaves fades away, revealing underlying pigments such as yellow, orange and brown. The red colour that occurs in some trees is caused by a breakdown of sugars.
Fall colours in Ontario are usually at their peak during the first week of October and the best displays occur with a combination of cool nights and sunny days. The Ontario Parks website provides a fantastic colour report of the best times and places for 'Leaf Peeping' (yes, that's a thing).
Well, that's enough education for one day. Here are some pretty pictures!
