You will have heard of ash dieback, but what else do you know about the rapidly growing number of health threats to our trees and plants? Tender Graft has always been aware of the importance of biosecurity, in other words doing what we can to reduce the spread of pests and diseases. This thorough free guide, Application of Biosecurity in Arboriculture , published by the Arboricultural Association, contains some excellent food for thought. It’s aimed at professional arborists but will be of interest to anyone who wants to get to grips with the details of horticultural best practice. Concern about spreading pathogens is one of the reasons why at Tender Graft we only use trusted suppliers when we buy plants. Thanks to the Chartered Institute of Horticulture for sharing this information on its Facebook page.
