Dean talks about autumn being the perfect time to give your trees a good pruning and why it's important for the tree's health. He also talks about how important trees are in terms of climate change in areas of drought. Dean runs through how to prune trees yourself, the correct equipment you need, and, if you're uncomfortable doing it yourself, what you should look for when hiring someone to do this for you. He also addresses a listener call regarding a kitchen sink faucet making a weird noise, which is being mimicked by a nearby bird!
