Tony Kirkham has a mission, one that will resonate with many arborists across the UK: "I'd like to get rid of the term 'tree planting'".The former Kew arboretum head says: "Our success rate of establishing trees isn't good in this country... I'd sooner see less trees planted and established rather than planting big numbers that fail to establish." In his conversation with HortWeek editor Matthew Appleby, Kirkham gives his thoughts on the "exotics" versus "natives" debate and reveals his "top future trees" which include his favourite "hard-working trees".On pest and disease threats to trees, Kirkham issues a stark warning. Experts say it is a case of "not if but when" Xylella enters the UK, and Kirkham says, with more than 400 host plants identified so far: "I think every woody plant is vulnerable. We really need to crank up our biosecurity."Other than Xylella, his the top concern is plane wilt, which "is spread by arborists" via tools, machinery, PPE and clothing, and which is "coming towards us pretty quick...we need to keep that out at ALL costs".He also talks about how arborists can handle the rising frequency and intensity of storms, recalling how he got Kew back up and running in the wake of the storm of 1987 that brought down so many trees that he considered "old friends".But despite the devastation that took three years to clear, he now says it is "the best thing that could have happened" - getting rid of unsafe trees, giving the Kew team a chance to replant and refresh the arboretum, revolutionising tree-planting practice.
