Hazelnut Trees and Truffles

Episode #37: Hazelnuts and Truffles

Hazelnuts are becoming increasingly popular as a high value crop…and can be grown together with truffles.

Some things go really well together, like pancakes and maple syrup – but there are other winning combinations that many people don’t know about – like growing hazelnut trees together with truffles! In this episode, Adam Koziol of Earthgen Tree Nursery in Ontario explains why hazelnut trees are becoming increasingly popular both in the home garden and as a cash crop. He also discusses how the trees can be inoculated so that they produce valuable truffles as well as nuts.
