Melinda's Garden Moment: Fall colors

Posted: Updated:

MADISON (WKOW) -- The Fall Color Report says fall colors will be at their peak in just a couple of weeks.  

Each fall, as the days shorten, our deciduous trees and shrubs begin this transformation.  The plants produce less of the chlorophyll that gives leaves their normal green color.  In fact, the chlorophyll starts breaking down revealing the underlying pigments of yellow, red, or orange.

All the same time these plants begin to create an abscission layer between the leaf and the steam. This barrier prevents the sugars produced in the leaves from moving down into the roots for storage.  Warm sunny days followed by cool nights without a hard frost mean more sugar and better red, orange, and purple fall color.

Genetics determine each plant tends to produce in fall, while weather and the plant's health influence if and how intensely the color will be expressed.
