Woodchip makes an excellent mulch for fruit trees in containers - to suppress weeds and to help retain water. It can also be used to make homemade compost, to add structure to worm compost, and even to grow mushrooms.

It's a sustainable resource, a waste product of pruning trees and fallen branches. It can sometimes be found at low cost or even free. And it's often widely available in  urban areas (look out for tree surgeons!) - although it can take some scouting around to find a supply.

I chatted recently with woodchip expert, Ben Raskin. Ben is Head of Horticulture at the Soil Association, and author of the Woodchip Handbook. Our conversation focuses on the different ways to use woodchip in container growing.
