Spider mites on roses - what to do?

How do you actually recognize spider mites?

You will not see the tiny spider mites themselves hopping around on your roses by chance; instead, the infestation shows itself through the fine white, not dissimilar spider webs on the undersides of the leaves, between the leaves and shoots and sometimes on the flowers themselves. The leaves are first slightly gray-white speckled, but discolor and dry up quickly and are then thrown off. Small, yellowish to orange-colored eggs can often be seen on the underside of the leaves.

Effectively prevent spider mite infestation

Spider mites love the heat, which is why they prefer to settle on plants that are in very sunny, dry and less airy locations. In addition, roses that are already weakened are increasingly attacked, as these - unlike healthy plants - no longer have a strong defense system. An airy location that is not necessarily in the blazing sun is ideal for roses - spider mites will not appear here anytime soon. For example, if your potted rose is standing directly in front of a wall (possibly in front of a white one), move it away and provide a cooling breeze. You can strengthen ailing roses with a regular horsetail tea cure, the brew also disinfects the soil and plants and not only keeps annoying arachnids,but also other vermin and various fungal pathogens.

Fight spider mites successfully

A product that is easy to manufacture and whose effectiveness is actually well known for powdery mildew often helps against spider mites: whole milk diluted 1:10 with water. You fill this mixture into an atomizer and spray the spider mites with it extensively for several days in a row. It is best to do the cure early in the morning when the beasts are still sluggish and slow. If you want to use stronger means, the various commercially available preparations based on rapeseed oil are recommended. Use chemicals as little as possible, because they not only kill unpleasant pests, but also all kinds of useful insects.

Tips

If your rose is in the pot, put it in the shower from time to time and give it a vigorous shower - then arachnids and other pests have no chance of colonizing. But make sure that the plant dries out quickly so that no fungi settle on it.
