Clematis Wilt - Diseases

Does my clematis have clematis wilt disease?

The first thing that we would check is whether the soil has become waterlogged. Clematis armandii is very hardy and can usually tolerate cold, but it will suffer if the ground is sodden. If this is the case then you could try moving it to a better drained site or improving the soil by adding sharp grit and plenty of organic matter. It may not survive if the roots have become severely damaged but it is worth a try.

If your plant is suffering from the fungal disease known as Clematis Wilt then it is usually recommended that the stems are cut back to healthy growth, from which new stems should develop. However the problem may recur. Planting clematis deeply can help to combat clematis wilt by encouraging more shoots to develop from below ground. That way, if you have to cut the plant back hard, it will be able to produce healthy new growth from the portion of the stem that is planted below ground - a sort of gardening insurance policy!

Plants and gardens have always been a big part of my life. I can remember helping my Dad to prick out seedlings, even before I could see over the top of the potting bench. As an adult, I trained at Writtle College where I received my degree, BSc. (Hons) Horticulture. After working in a specialist plantsman's nursery, and later, as a consulting arboriculturalist, I joined Thompson & Morgan in 2008. Initially looking after the grounds and coordinating the plant trials, I now support the web team offering horticultural advice online.
