Autumn is an amazing time of year as the colourful display of the leaves on the trees can be stunning. This process is complex but in short leaves contain Chlorophyll hence appear green, and when this is no longer produced the leaves change colour. The key triggers are light levels, weather and chemical reactions.

This year so far has not produced great growing conditions for some species of tree, whilst others have flourished. In particular Korean Hornbeams have not produced the same level of growth as last year.
