Hi I have a similar problem to a post a few years ago. I planted Mint Crisp in June 2017 and it grew beautifully and survived the Beast from the East in March 2018. It vigorously climbed higher than our 6ft fence and has a similar width but suddenly much of it is turning brown and the plant seems to be dying off. Interestingly below it is what was once a small,helathy azalea and this is also wilting badly yet the plants on either side are healthy and showing good growth. It is on a North facing fence but this also means the soil remains pretty moist so its not a lack of water problem. Any ideas?
