Autumn is fast approaching which means you’ve probably noticed the leaves on your trees changing colour.  This is completely normal don’t worry, but you may be wondering what causes this change every year. That’s why we’re here to give you all the information you need. 

It all has to do with something called Chlorophyll. Chlorophyll is the pigment inside leaves that give them their beautiful green colour.  All throughout the spring and summer, your leaves are continually producing chlorophyll and that’s what keeps your leaves looking nice and healthy. However, when it starts to get colder, the leaves start to slow on their chlorophyll production. The production makes smaller and smaller pieces and this is when the leaves begin to change colour. The tree can actually reuse some of the particles in the chlorophyll. This is what gives the leaves the typical orange/red colour right before they fall off. 

Temperature and amount of sunlight will also have an effect on when your trees start to lose their leaves. If they are still exposed quite bright sunshine and moderate temperatures, the leaves may stay greener for longer than one who’s in a shaded area with temperatures more on the chilly side.

If, however, the leaves on your trees start to change colour out of season, this may be a cause for concern. Out of season leaf discolouration often suggests some type of decay or infestation. While you can leave it and hope the trees natural defences sort this out, it’s best to act early and have a specialist come take a look.
