In order for you to enjoy healthy roses, we recommend that you provide some conditions
- Choose varieties for your garden that are as robust as possible. We attach great importance to breeding resistant and thus low-maintenance rose varieties.
- A suitable location and good care contribute to the health of your roses.
- Provide a habitat for the natural enemies of animal pests by keeping some areas of your garden untidy and naturalistic.
- Feel free to offer insect hotels and plant insect-friendly plants, such as varieties from our Bees paradise rose assortment.
It is completely natural for platnts to occasionally be affected by fung. However, to ensure that your beloved roses remain healthy, we habe summarised the best prevention tips for you here: :
If possible, do not water your roses from above with lawn sprinklers, because fungal pathogens spread better on moist foliage.
Fungus-infested leaves on the ground should be picked up regularly and disposed in household trash.
If your tolerance level is exceeded to the point that you want to resort to chemical pesticides, please apply them as a preventive measure when the young leaves are forming. Change the active ingredients so that no resistant strains of pathogens develop.
Since the registrations of plant protection products often change and there are different suppliers, no products are listed here. Please ask directly at your local dealer and be sure to follow the instructions for use when applying the product.
Powdery mildew
It forms a white coating on the upper side of young leaves and buds. Pruning is recommended. Beware: downy mildew has a white-gray coating on the bottom of leaves and flowers and purple-brown leaf spots, which may be separated by leaf veins, on the top of leaves.
Downy milew
causes purple-brown leaf spots, which may be delineated by leaf veins, to appear on the upper side of the leaves, as well as a white-grey coating on the underside of the leaves and on the flowers.
Black spot
The common black spot disease forms brownish-black, round spots on the leaf surface, the edges of which fray in a star shape. The leaf turns yellow and falls off. Collect the leaves and dispose of them in the household waste. Try home remedies; in case of severe infestation, spray preventively.
Rose rust
can be recognised by small orange dots on the underside of the leaves, which look like rust spots. Remove and collect the leaves and dispose of them in the household waste. Try home remedies; in case of severe infestation, spray preventatively.
Bark rot/bark spot
disease affects shoots that are too soft and immature, forming elongated, dark spots on the bark. Cut off generously and dispose of in household waste. Disinfect shears. Countermeasures include fertilising as needed.
Grey mould
Botrytis tends to occur after prolonged rain and covers flowers, buds and young shoots with a grey fungal coating. This can be remedied by cutting off the affected parts and disposing of them in the household waste. Disinfect the shears
Aphids
suck mainly on young shoots and buds. Spraying with a powerful stream of water is often sufficient as a countermeasure. Natural antagonists such as tits and ladybugs will soon assist you. If necessary, you can also spray leaves and buds with a green soap solution and then wash them off with clear water.
Leaf roller wasp
The feeding damage caused by the white-greenish larvae of the leaf roller moth, which occur from May to July, causes the leaves to curl up and turn yellow. The larvae, which are just under 10 mm in size, are found in these leaf rolls. To remedy this, cut off the curled leaves and destroy them.
Rose leaf wasp
Traces of cockroach feeding by the larvae of the rose leaf wasp! The larvae are green and spotted and approximately 10 mm in size. They are difficult to see with the naked eye. Encourage birds to visit your garden. They serve as a popular food source for rearing young birds.
Spider mipes
(syn. red spider) cause damage by sucking and can be recognised by the fine webs around the flowers. It helps to humidify the environment, remove infested shoots and dispose of them in household waste. A pest that is difficult to control.
Rose chafer beetle
The rose chafer beetle (approx. 10–20 mm in size) and the rapeseed beetle (approx. 2–3 mm in size), which destroy the inside of the buds, can be easily collected by hand in the morning.
Thrips
The ‘Californian flower thrips’ is spreading rapidly throughout Germany, leaving behind stunted, partially shaved flower buds. It is difficult to combat these insects, which live hidden inside the bud. Dispose of infested buds in the household waste. A pest that is difficult to control.
Rose leaf miner
The rose leaf miner is an inconspicuous moth that rarely appears. The larvae eat tunnels between the upper and lower sides of leaves. This leaves behind damaged leaves. It is not possible to combat this pest in the garden; remove infested leaves and dispose of them in the household waste.
Rose shoot borer
There are two types of rose shoot borer: one that bores upwards and one that bores downwards. They attack garden roses from June to September. The shoot tips suddenly wilt and dry out due to the larvae eating away at the vascular tissue. As a countermeasure, the wilting, infested shoots should be cut back to healthy wood and disposed of in the household waste.
Cicadas
You can recognise an infestation of rose cicadas (similar to aphids, white-green, jumping or flying) by the white speckles on the upper side of the leaves. If necessary, chemical pesticides can help.
Rose gall waps
cause shaggy-looking galls. Egg laying causes the formation of these ‘galls’, in which the larvae develop protected from harm. The only way to combat them is to remove the galls.
Deers
also like to eat young rose shoots and buds. They can be scared off by strands of human hair, buttermilk or, best of all, preparations available from specialist retailers.
Voles
like to eat the bark of rose roots. You can use box traps, please handle with gloves to avoid odor. Apple, celery or peeled carrots serve as bait. Support natural predators such as birds of prey by perching or weasels by offering wood or rock piles.
Rosette virus
manifests itself as witch's broom growth, infestation leads to twisted shoots, excessive thorn formation and bright red leaves. Transmitted by mites, spreads through infected material. Dispose of infested plants in household waste or burn them. Always disinfect or flame scissors.
Mosaic virus
causes yellowish, mosaic-like spots on the leaves and can impair growth. Transmitted by piercing-sucking insects (cicadas, aphids) and mechanically. Dispose of infested plants in household waste or burn them. Always disinfect or flame scissors.
