Why Do Leaves Change Colour?

October 13, 2017

In the summer chlorophyll gives leaves their green colour and is so dominant it hides the other colours in the leaves. But in the fall, chlorophyll in the leaves breaks down allowing the other colours to finally shine through and show their beautiful reds, yellows, and oranges. So with fall at our doorstep we look toward putting our gardens to rest for the winter months but before the dormant season is in full swing we have a new array of colours to admire amongst the plant material.

This is also the time to treat trees from an accumulation of moss and algae which can diminish overwintering insect populations from infesting the trees and can further reduce the need for pesticide applications during the growing season. We use a safe and low toxicity treatment to maintain the optimal health of deciduous trees. Contact our office for more information.

The following are trees with great fall colour.
