The mellow fruitfulness of Autumn has been heralded by the subtle change in temperature and darker mornings and evenings in the garden. For Lucy Chamberlain and Saul Walker this starts one of their favourite times of year as Lucy's vegetable patch is at maximum yield producing food for East Donyland Hall and Saul revels in the changing colours in the canopies of his precious treescape at Stonelands. So join us throughout the season as we bring tales of crispy leaves, hibernating plants and plenty of pumpkins!

Autumn leaf colours are one of the marvels of our temperate climate, but what exactly is happening within the leaf, and why do some trees and shrubs exhibit more glorious tones than others? Lucy and Saul muse on this topic, delving into the world of chlorophyll, anthocyanins and carotenoids. Leafmould, too, is at our fingertips at this time of year - is there science behind this? You bet!
