Although the pimple nut is very robust, its root damage can be doomed by improper care. Which pests are particularly harmful and how you can avoid care mistakes, read here.

Pimpernuss - recognize and combat diseases and pests

If the care instructions are observed, the pimple-nut remains largely spared by diseases. The robust plants handle our climate well and have few requirements regarding location or irrigation. Nevertheless, the hobby gardener should keep a close eye on his plants, because the plant is unfortunately less well prepared for pests. However, a courageous intervention can help to prevent worse and preserve the health of the clatter nut.

Which pests can make the pimpernus dangerous?

  • cockchafer
  • beetle
  • weevil

Why pests pose a serious problem

If a plant is attacked by aphids, for example, then this is not to be overlooked and the hobby gardener can quickly remedy the situation and drive away the pests with suitable means of the plant. It becomes more difficult when the pests make their roots. An infestation is then often noticed too late. Once the root has been sustainably damaged, the pimple nut will be hard to recover. That's why it's even more important to keep a close eye on the chatterbox. If external damage, such as leaf staining and a rather stunted growth, is evident, it can be deduced from damaged and stunted roots.

" Tip: In root damage, the plants can be easily removed from the ground.

Those who suspect a root damage, should excavate the plants as a precaution and look at the root closer. For this purpose, the soil should be largely removed. If at the root gnawed or peeled areas, it is to be assumed that a root damage by insects. This can vary and have different effects on the plant. Older plants, which have already formed a stable root system, can tolerate a root damage caused by pests usually quite well. Damaged roots, on the other hand, can have serious effects on younger plants, sustainably damaging or even completely destroying the plant.

If only slight root damage is evident without much bite, the weevil larvae may have been at work. If completely separate root sections are found, this indicates an attack by cockchafers. Pest determination is no easy task. Some larvae can only be detected in deeper soil layers.

" Tip: If a root damage is suspected by pests, the pimple nut should in any case move to a new location.

❍ Cockchafer - the deadly danger

The development of the May beet runs in several cycles. While hardly any beetles are spotted in some years, the beetles are quite common every four years. Mass multiplication is not uncommon among cockchafers. The cockchafer can cause baldness in deciduous trees. This is usually well tolerated by healthy plants. However, if the pimple nut is already damaged, it becomes more susceptible to further pest infestation.

A far greater danger are the grubs, the cockchafer larvae. These develop in the course of three years in the ground and infest the roots. If this remains unrecognized, the pimple bushes can completely die off.

❍ Beetle at the factory

Even beetle beetles are often found at the flapper nut. Fast beetles are widespread and include about 10,000 species worldwide. This pest genus owes its name to the gift of literally catapulting itself into the air with the help of its jumping apparatus. The larvae live in the ground. For example, the wireworms of the seed-billed beetle can be dangerous to the roots of the pimp-nut.

❍ Weevils - the species-rich pest

The weevils are particularly species-rich. There are around 50,000 species worldwide. In Germany alone, there are about 1,000 species. It is believed that the weevils are the most species-rich living thing of all. The corn beetle was already known in ancient Egypt. A direct danger for the Pimpernuss represent the weeping weevil and the Grünrüssler dar. Also here are not the beetles themselves the biggest danger for the Klappernuss, but the living in the soil larvae, which attack the roots and remain unnoticed over a longer period of time.

What signs indicate a root damage?

If you notice the following harmful effects on your plant, it can be assumed that the rooting problem is:

  • stunted growth
  • pale crown
  • Training weak hunger drives

Now fast action is required.Young plants do not yet have a sufficiently developed root system and can usually be pulled out of the ground without much effort.

What to do at Wurzelelfraß?

If the pests are visible on the plant, they can be easily collected. The succeeds in potted plants very well, designed in outdoor plants, however, consuming.

Predators can be used against larvae. In the larvae of the beetle, for example, different types of fungi are effective. Weevil larvae can be fought with nematodes. These tiny roundworms can be obtained from specialist retailers and reach the ground via the irrigation water.

In the case of heavy infestation of the roots, the plant should be transplanted as soon as possible. Replace the soil completely. In older plants, no failures should be feared. The plants rooted new and the damage will be barely visible.

The soil at the old location of the pimple nut should be specially processed and disinfected. Here are special insecticides have proven.

Avoid care mistakes

Damage to the pimple can also be caused by care mistakes. The biggest danger is choosing the wrong location or over-irrigation.

care errorsappearanceactivities
wrong locationThe plants are not bright and sunny enough, they show a stunted growth habit. The flowering and fruiting stay away.Move the plant to a bright and sunny to partially shaded spot.
too much waterIf the pimple nut is poured too much, the irrigation water builds up in the soil. Waterlogging attacks the roots. The plants wither and die if nothing is done about it.Remove the plant from the ground and free from wet substrate. Put the pimple nut in a new, dry location. From then on, pour less.
not enough waterThe plants can supply themselves well with moisture via the roots. Young plants wither quickly if they are not watered regularly. Also in the bucket the plant will go in, if it is not poured regularly. This also affects older plants.The plants should be watered immediately. By spraying more frequently, you can also create a high level of humidity, so that the pimple will recover faster. From then on, water more frequently and control the soil.
