Wild wine - diseases and pests
The marmot (Parthenocissus), colloquially often referred to as wild wine, Mauerkatze or Mauerwein, is often used for greening of facades, pergolas or walls as well as ground cover. The very fast-growing climber can grow up to 12 meters high and several meters wide, it also forms a very dense trellis. With regard to viruses or bacteria-causing diseases or pests, the Wild Wine is quite resistant - except when it comes to the dreaded Verticilliumwelke.
Mildew is extremely rare
In contrast to the grapevine (Vitis vinifera) - with which the wild wine is often confused - it has developed a method to protect itself from mildew or downy mildew. As a result, Parthenocissus is almost resistant to these fungi, which quickly cover leaves and shoots with their greyish-white fungal turfs and can destroy entire stands within a short time. If you ever find any signs of mildew - no matter what kind - seek rapid action to control the infestation.
Common problems
However, wild wine usually has to deal with quite different problems.
verticillium wilt
Verticillium wilt, too, is a disease caused by fungi that infiltrates the plant from the ground, causing leaves and shoots to die. So far no herb has grown up against this disease, on the contrary: Infested plants should be removed promptly and completely to prevent further spread. You can only prevent the disease by carefully following the instructions on the location and care of the wild wine.
Wool and scale insects
Significantly more harmless, however, are the up to five millimeters large wool and scale lice, whose presence in the white, especially on the undersides of the leaves occurring spines is to be noted. However, they are not easy to fight, even if there are effective antidotes. As a proven remedy has proven a mixture of one liter of water, a hefty splash of detergent and three tablespoons of vegetable oil, which is sprayed on several days in a row on the affected areas.
Tips
On the other hand, if your Wild Wine does not really want to grow, or if the leaves turn yellow at an unprecedented time, there could be a lack of nutrients or water. In this case, the location should also be checked.
