Blood redcurrants are among the most robust ornamental plants that can handle cold, wind and weather quite well. Except for a few diseases, they are resistant to diseases and pests. Symptoms and measures in diseases of red currants.
What is it, if the currant is not blooming?The most common disorders of the currant
Leaf fall disease
The leaf drop disease often occurs when the spring has been very humid. The leaves initially show small brown spots, which are getting bigger and bigger with time. The leaves finally fall off and the plant grows only miserably. The cause of leaf fall disease is a fungus called Drepanopeziza ribis.
Cut off all affected shoots, down to the healthy wood of the main shoot. Remove the cut parts of the plant and collect all the fallen leaves.
A good prevention is the clearing of the shrub in spring. In doing so, cut out too tight shoots. Occasional spraying with stinging nettle broth or tansy mud also helps to fight the fungus.
wilt disease
If whole shoots begin to wither and die within a few days, then the red currants may be suffering from the wilting disease. It is triggered by a fungus from the family Verticillium.
You can not do much against the wilting disease. Cut off all affected shoots if the fungus has not yet spread over the whole plant. In case of heavy infestation, it is only necessary to completely remove the red currant.
Prevent a loose, water-permeable soil when planting a red currant. Heavy soils should be mixed with some sand.
Never let the red currant dry out
When the leaves of the plant wither, it is not always a disease. Sometimes too much drought or waterlogging is responsible. Make sure that the plant is sufficiently watered when it is very dry. A site with permeable soil prevents waterlogging.
Tips & Tricks
If the currant blooms in the spring does not bloom, it is almost never a disease. The cause of non-blooming is in most cases a wrong cut. Bloodcurrants may only be cut shortly after flowering. In later cuts, the plant parts are removed, on which the flowers develop next spring.
