Recognizing and fighting common diseases at the slit maple - That's how it works
Two widespread fungal infections target most maple species and do not spare the maple. Find out here which symptoms can be used to identify the diseases with tips for ecological control.
Verticillium wilting - Tips for diagnosis and control
Fungus spores of the genus Verticillium enter the slot maple via the soil and clog the pathways. Visible symptoms of an infection are in places withered leaves and dry branches. From the base, the disease spreads to the top, so that an Acer palmatum eventually dies. If you cut through affected branches, dark brown ring-shaped discolorations can be recognized. Effective fungicides are not available yet. How to fight Verticillium disease:
At the new location, prepare a spacious plant pit with a sole of sand or fine gravel drainage at the bottom. One third of the excavation is mixed with rhododendron earth. The more permeable and airy the soil, the better the chances are that the sick slit maple will regenerate on its own.
Recognize and combat mildew - that's how it works
Deeply slit leaves in beautiful colors are the most beautiful jewelery of the Acer palmatum. How devastating when the ornamental leaves are covered with a floury-gray mushroom turf as a result of infection with mildew. Later, the leaves turn brown and fall sadly to the ground. It does not have to be that far, because you can fight the disease with fresh milk. That is how it goes:
Fill the solution into a hand sprayer. At intervals of 2 to 3 days, spray the remaining leaves on the top and bottom sides with the milk water until no more disease symptoms appear.
Tips
The symptoms of Verticillium Wither and Frost damage may seem confusingly similar at first sight. There is one crucial difference: Withering fungi make a sliced maple slowly and in places die off. Frostbite causes over-night drying leaves, leaves and loose shoots throughout the plant.
