Worries about wilt
My clematis had three flowers in bloom and another 12 almost ready. Now it looks like this. Is this clematis wilt? Wayne Taylor, Pudsey, West Yorkshire
Your clematis has succumbed to wilt disease. Regrettably, there are no chemical controls for this debilitating problem. All you can do is cut back diseased stems to ground level and bin or burn infected shoots.
Pleasingly, the fungus does not kill the plant and new shoots will appear from below the soil surface within six weeks or so.
If there are several diseased shoots that need cutting out, disinfect your secateurs between removing each of them. Clematis that are normally resistant to wilt include varieties of viticella, montana and alpina.
Wilt is a common clematis complaint, but doesn’t usually kill the plant
