| Pests, Diseases and common disorders of Clematis |
|
Clematis are quite trouble free plants in the garden provided basic rules are followed. I have included a list of every common problem, most of which are minor, but worth including for your passing reference.
2. Plenty of fertilizer: Clematis are fast growers from spring to autumn. To achieve a strong and vigorous plant, you need plenty of tucker. In the nursery we feed our clematis first thing in spring, when they are just shooting, and after each cut (the clematis are cut after the end of each flush of flowers). Do not feed your clematis when they are just about to flower as this will cause them to drop their flowers early, rush off and grow. I prefer to use a slow release fertilizer such as Osmocote, but any good fertilizer would do. Fertilizers high in potassium (such tomato food) will promote good sized flowers and help with disease resistance. 3. Pests to look out for: At certain times of the year, you can expect certain pests. Some years there maybe little or no problem pests, then other years they're everywhere. By keeping a careful eye on your garden, you can often prevent a problem before it gets out of hand. Watch out for some of these guys, they are probably on many of your other garden plants too! None of these pests are exclusive to clematis, but they can be a problem anyway. Winter/ early Spring: Slugs and snails Spring/ Summer: Aphids, Earwigs, Caterpillars, Thrips, Two Spotted Mites, Azalea Lacewings. Autumn: As the weather cools down, so do the pests, except for slugs!! I do not like the idea of using chemical sprays in the garden because they can cause all sorts of problems with your garden's ecosystem. If you kill everything you can see, what are the birds and beneficial insects/ spiders going to eat. Some problems are only short lived, so give your beneficial creatures a break and only use chemicals as a last resort and only as spot sprays. Having said that, there are many new chemicals that are soft on the environment, so make sure you ask your local nursery what impact your use of a chemical will have on your garden good guys.
