There is often talk of stains on rose petals. These black or red spots appear on both the top and bottom. But these mushrooms can not only appear on the leaves, the shoots and branches are not immune to them.
The bark brandy mushroom
The so-called bark brandy is a problem for the gardener. Therefore, you should always check the shoots of your roses. If you find reddish brown spots, you have to remove the shoots generously. Here you should cut into healthy wood to prevent spreading. You should dispose of the pathological shoots in the household waste and never put them on the compost, as they can get back into the soil.
Coverage in winter
To prevent this fungal attack and promote wood maturity, you should cover your roses in winter with pine twigs instead of earth and do not forget to remove the twigs promptly after winter. You should also avoid nitrogen fertilizers in autumn.
