Hollyhocks are resistant to many diseases and pests, but they are not immune to it. What you need to do in an emergency, read here.Hollyhocks are really popular with gardeners. And of course not without reason. In a sunny spot you will bloom until autumn. They are very easy-care, undemanding and largely insensitive. This does not mean that the hollyhock can not be attacked by pests.
If it has come to an infestation, you should react in a timely manner to save the diseased plant. Here are some options and means available. But beware! Only when organic-natural remedies show no effect, you should resort to the chemical leg.
Which pests do hollyhocks become dangerous?
Hollyhocks attract various pests. For snails, sawflies, spider mites, caterpillars and beetles, the leaves are a popular food source. In addition, mallow fleas and mallow shrews can attack.
You recognize the Fraßschädlinge upon closer inspection of the leaves. Sometimes only traces of food appear on the foliage. Serrated leaf margins and small holes in the leaves indicate a low infestation, with completely eroded leaves, the situation is clear anyway.
Prevention of feeding pests:
Healthy, strong plants and an optimal location are the best prevention. Fertilize your hollyhocks with a commercial flowering plant fertilizer at intervals of two to three weeks. Hollyhocks love the sun, so the location should be warm and protected. When the moisture balance is in balance, pests also have lower chances. The plants need regular watering, but waterlogging weakens the body's defenses.
To control pests on hollyhocks biologically:
If there are only a few insect pests on the plant, simply collect the hungry animals. Natural remedies help with a stronger infestation.
➜ stinging nettle
Aphids and other pests fight successfully with a nettle - if you yourself are not sensitive to odor, because the manure develops an unpleasant odor.
»How it works: Put shredded nettle leaves in a bucket with rainwater and leave the mixture for a few days. The finished manure is diluted with water and is sprayable.
" My advice: Odorless, but equally effective is a lye made of soap and water. Spray in the morning, then the effect is best.
➜ Loosen the soil
The mallow flea most often occurs when the soil is too dry. In this case, watering and loosening the earth helps. An insider's tip is a match that you stick with the sulfur's head in the ground.
➜ Fight snails
As long as only a few people are on the road, collecting helps. With an increased incidence, slug pellets are useful (for example, here). Although this is not biological, it is very efficient in case of a snail plague. You also protect all other plants in your garden.
If the pest infestation is very strong, an insecticide must be produced. If the plants can not be rescued, dig the hollyhocks together with the root and destroy them. But not on the compost, as the pests would continue to spread unhindered here.
