Nothing can harm the mulberry tree so quickly. But it can happen that spider mites get stuck, which at best are simply showered off.

Mulberry trees that are not outdoors are more likely to be affected. Mulberry tub plants in particular have to fight parasites much more frequently in their winter quarters. Since mulberry trees are usually only affected by spider mites, there is a very good chance that the plant will fully recover from them. As with all other plant diseases and pests, it is important to intervene as early as possible to minimize the damage. What all hobby gardeners should know about a possible pest infestation and potential dry damage in the mulberry tree and how these problems can be easiest dealt with, we give below in detail.

Diseases and damage to the outdoor mulberry tree

If it is a free-range mulberry tree, it is usually drought damage that causes problems for the plant. De-icing mulberry trees can also be significantly affected by road salt. This can be seen from leaves that either curl up or have unsightly stains. A fungus or other pest infestation on the mulberry tree that stands outdoors, however, hardly ever occurs.

While damage to plants caused by drought means that the plant should be watered as quickly as possible, damage by road salt should be avoided as far as possible. In the worst case, they can only be fixed with much more effort. This is simply due to the fact that road salt only slowly settles in the deeper layers of the soil. This can mean that the plants will continue to absorb the road salt from this soil for years to come. Thus, the road salt damage to the plant itself may only become noticeable when the connection between the damage and the road salt is hardly visible.

If only new earth helps

It is therefore better not to use road salt near the garden and plants. If your mulberry does not recover despite sufficient watering, this can be an indication of road salt damage or poor soil quality. In this case it is important that the soil around the mulberry tree is completely replaced. Then the plant should be watered and fertilized sufficiently - at least in the coming weeks. After all, the plant also has to recover from road salt intake and the associated lack of nutrients. In addition, given the exchange of earth, it first has to grow on the spot again.

Parasite infestation on the mulberry tree - preventive measures and pest control

If your mulberry tree was planted in a bucket on the terrace or balcony, it will have to move to winter quarters during the cold season. This makes the plant much more susceptible to pests, where spider mites in particular can be a problem. To prevent this infestation, it is important to consider the following points for the winter quarters:

  • the mulberry tree should be as airy and cool as possible
  • a heated room is not suitable as a winter quarters
  • slight frost is not a problem for the mulberry tree in the winter quarters

In fact, slight frost in the winter quarters of the mulberry tree is even recommended. This is simply due to the fact that frost does not get spider mites. A spider mite infestation is completely impossible at such icy temperatures. Thus, all pesticides are completely unnecessary in such a situation.

Fight spider mites on the mulberry tree

If spider mites with their fine webs are noticeable on your mulberry tree in the winter quarters, then the tree should be thoroughly brushed off. This also applies to the undersides of the leaves, where special care is required when removing the mites. The water that is used for rinsing should be as free of lime as possible. In addition, it is important that the mulberry root ball does not come into contact with the rinse water. Because with the water, the spider mites are also rinsed off and the spider mites could get stuck in the root ball. So it's best to take a plastic bag or tarp to protect the roots. Before the tree is exposed to the frosty temperatures of the winter quarters again, it should be completely dry.

Alternatively, beneficial organisms can be used in the fight against spider mites. Both predatory mites and lacewings are available in specialist shops for these purposes. However, if there is only a slight infestation and the mulberry tree is rinsed off promptly, pest control with beneficial organisms is often not necessary at all. If you prefer to use an insecticide, the best thing to do is choose an agent that is made from rapeseed oil. This remedy is not only just as effective, it is in no way harmful to the environment. An insecticide on a natural basis is also particularly useful when children or pets are out and about in the garden in which the mulberry tree is supposed to be standing after the winter.

Pest control in mulberry trees - Summary of key information

Whether damage from spider mites or excessive drought is suspected, prompt intervention is one of the most important basic requirements so that the mulberry tree can fully recover and take as little damage as possible. We have once again summarized the most important tips for handling pests in the mulberry tree:

  1. When mulberry trees are sick outdoors: water better or completely replace the soil around the tree and then fertilize and water sufficiently.
  2. The perfect winter quarters for the mulberry tree are very well ventilated and the temperatures there are just below freezing.
  3. Spider mite infestation: Rinse the plant well and protect the root ball.
  4. Rapeseed oil insecticide, predatory mites or lacewings can also eliminate the troublesome mite infestation.
