There are plant diseases, there is no waiting. The clematis wilt is such a treacherous fungal disease. Out of the blue she strikes quickly and mercilessly. Anyone who gives me time to fight has already lost the fight. Fast reaction is therefore required. The climbing artist is supposed to do well and continue her flourishing work. With the right measures, this request is by no means hopeless.
Clematis wilt, what exactly is that?Clematis wilt is a disease caused by fungal pathogens. The spores of the mushrooms are already in the ground and lurking only on an opportunity to attack the clematis plant. Open spots caused by injuries are welcome entry points. After they have attacked the plant, they unfold their destructive effect without much delay and at a breathtaking speed. Under the name Clematiswelke, however, hide two different diseases. They are caused by different fungi and also differ in the later course of the disease. The two types are:
1. the phoma wilt
2. the Fusarium wiltIt is important to distinguish and unambiguously identify these two species. The type of wilt has a significant influence on the approach to control.
The Phoma wilt
As soon as the first signs of wilt appear on the Clematis, immediate action should be taken.
- remove all withered leaves immediately
- If necessary, entire shoots must be cut off
- collect any fallen leaves from the ground
- removed parts of plants belong to the residual waste
- Mushroomed plant parts should never be composted
- spray the pruned vine with commercial fungicide
How fast the climber recovers depends on how far the disease has progressed. If the fungus has not yet reached the inside of the plant, the clematis recovers quickly. Otherwise, the plant is often unable to help with fungicides. Sometimes, however, it can happen that the Clematis survives the complete aboveground death. After about three years she drives out again. Those who want to experience such a positive surprise should leave the roots in the ground and not dig up.
The Fusarium wiltThe more common Fusarium wilt, also called Fusiarose, is caused by a slime mold called Coniothyrium clematidis rectae. He uses the smallest injuries to the plant in order to get from outside into their pathways. From there, it spreads in the supply system of the plant, and clogs parts of it.
- Plant parts above the affected sites suffer
- they do not get enough water anymore
- they also do not reach nutrients
- as a result of the deficiency supply, they wither and die abruptly
- Leaves first get a brown border
- Edge continues to spread to the middle of the sheet
Which clematis are affected by the Fusarium wilt?In fact, any clematis can contract this wilt. However, some Clematis plants are particularly vulnerable because they are not sufficiently resistant or provide an unprotected attack surface. These are the following:
- large-flowered varieties
- young plants
- old forest vines
- weakened by care mistakes climbers
- Plants with damage to their young shoots
Discover Fusarium wilt in good time
Even with this type of wilt, it is useful to discover their signs as early as possible through regular inspection. But unlike the phoma wilt, this disease occurs a little later. These mushroom pathogens like warmer weather with temperatures over 20°.
- The first signs are expected from mid-June
- individual shoots that suddenly wither for no apparent reason
Successfully combat Fusarium wiltThere are no effective fungicides available to combat Fusarium wilt. It is therefore all the more important to take alternative methods of control without delay. Here, too, must be used consistently for pruning shears. However, it is not enough to remove only the withered parts of the plant.
- a radical cut is inevitable
- All shoots must be cut close to the ground
So that the fungus can not strike again, all above-ground parts must be disposed of completely and safely. The soil must also be searched for old, fallen leaves. The pathogen can still cling to it, they too must be collected and destroyed. If the disease was discovered at an early stage, there is a good chance that the climber will recover. As the fungus does not penetrate the root area, new shoots may sprout after some time.
Successfully avoid wiltingThe best protection against both wilting species is not to let it get that far. The possibilities of successful prevention start with the plants and continue with the ongoing care. Plants that grow in a suitable location and receive optimal care are stronger and more resistant to this pathogen.
- only strong plants, buy in 2-3 liter containers
- the optimal location is protected from wind, rain and sun
- Plant rootballs deeper
- when wall planting on sufficient distance pay attention
- always follow the care rules
- Drainage prevents waterlogging
- Never rake soil, roots and shoots can be damaged
- in the root area, never over the leaves
Choose resistant species
Some original clematis species have proven to be quite resilient. Many new breeds have also targeted resilience. If you want to be on the safe side, you can rely on these varieties right from the start.
- original varieties from the Italian Clematis Viticella Group
- large-flowered hybrids such as spring-blooming 'Multi Blue' and 'The President'
- summer flowering clematis: z. B: 'Comtesse de Bouchaud', 'Ville de Lyon' or 'Yukikomachi'
