Why do leaves change colour?

Let's face it leaves are the food factory of the tree! So why then do they change colour in Autumn I hear you ask.

Virgina Creeper by Ming chai

Moisture that contains valuable nutrients and minerals is sucked out of the soil by the roots and passed up through the tree into the leave. They mix with air and are converted into sugars and starches (tree food) that are absorbed by the tree to make it grow the energy needed for this process comes from the sun. Sunlight is trapped in a leaf by a green pigment called chlorophyll. It’s chlorophyll that gives leaves their green colour in spring and summer then the days grow short and night time temperatures fall, the tree realises that autumn and winter are coming. Most trees do not grow in autumn and winter, so there is no need for food and the ‘food factory’ closes down the chlorophyll left in the leaf is not needed and starts to decompose. That means the other pigments from the sugars and starches start to show - and they’re the golds and reds that we know as autumn colours.
