I would like to say thank you to Jason and his team for giving us advice on suspected Japanese Knotweed shrubs. The plants are on some land we are going to lease for 25 years and we needed urgent advice before proceeding with the lease negotiations. We sent Jason a series of photos and he responded with a phone call within 7 hours which was incredibly helpful.
