Trees show off their spectacular colours

Mitchell Shire’s trees are starting to reveal brilliant reds and vibrant yellows, with bright leaves appearing on streets and properties.

The municipality has a wide range of shedding tree and plant species that astound residents each year with spectacular displays of colour before the leaves fall. But what is it about a tree that turns it into a visual masterpiece?

Like most healthy trees, the quality of soil drives how a tree performs and that includes what colour a tree produces in autumn.

Species that produce red/deep scarlet or crimson colours are usually growing in acidic soil (less than 7 pH). Mitchell Shire’s Oak trees (Quercus), Maples tree (Acers) and some Ash trees (Fraxinus) produce this colour.

Trees located in neutral or alkaline soils (greater than 7pH) can produce vibrant yellow colours. The species commonly found with this colour are Honey Locust (Gleditsias), some Oaks and some Elms trees (UImus).

People with trees on their property are encouraged to let them show their natural colours. An underperforming ornamental tree can be turned into an autumn neighbourhood superstar with some simple soil conditioning.

If you have any spectacular images of the trees in your neighbourhood, please share them through #DiscoverMitchell (Instagram and Facebook) or by emailing

“Part of the attraction of living in Mitchell Shire is our beautiful landscape. People come here for a tree-change. While we can’t get out and enjoy most of the trees right now, we will bring some of our neighbourhood superstars to you through photos.,” he said.

“A colourful tree can be so uplifting for residents so make sure to log on to our website and social media channels for more.”

“As we start heading into the autumn and cooler months it’s an exciting time for any person with an interest in trees or gardening. Autumn in Mitchell Shire Council gives us all a chance to find out what that Oak hiding in the side street really was,” he said.

“pH can also be a defining factor in many other forms of tree health, generally speaking trees grow in pH levels of 4 to 8. Certain species will tolerate higher or lower pH levels, so it is important to identify what species your tree is prior to any attempts at pH modifications. It is important to note that altering soil pH beyond the recommended pH levels may be detrimental to the tree and it’s health.”
