In the entire Mediterranean region, the palm weevil threatens entire populations of Mediterranean plants and has become a problem there. Thank God this pest hasn't been able to spread here yet. Nevertheless, even in these areas, palm trees are not immune to pest infestation. However, if they are detected in time, the animals can usually be fought successfully so that the palm tree does not suffer any permanent damage.
What pests attack palm trees and how do you fight them?
The most common pests on palm trees are spider mites, mealybugs, mealybugs and aphids. Insecticides can be used to combat spider mites, but repeated spraying is necessary for spider mites. Alternatively, plant sticks or beneficial insects can help in the winter garden. A good indoor climate and regular spraying of the leaves have a preventive effect.
Spider mites
The tiny little arachnids are often not even noticed by plant lovers in the early stages. Only when the fronds turn yellowish to white do many people notice that something is wrong with the palm tree.
You can make spider mites visible by misting the compartments generously with water. To protect themselves, the animals form fine webs in which the water droplets get stuck. The animals can also be discovered using a magnifying glass.
Remedy
Untreated, spider mites usually lead to the death of the plant, so fight the insect pests consistently:
- Home remedies are usually not very helpful and difficult to use due to the size of palm trees.
- Therefore, treat the plant with a suitable insecticide.
- Inject several times a few days apart.
Prevention
Spider mites love dry heating air. Ensure a good indoor climate with an evaporator or an indoor fountain. Regular spraying also has a preventive effect.
mealybugs and mealybugs
Mealybugs and mealybugs protect themselves from environmental influences and predators with a white, downy or oily coating. This makes combating it somewhat difficult, as many spray agents do not penetrate this layer.
Combat
- Spray the palm with a synthetic agent and repeat the application every few days.
- Plant sticks that are inserted into the soil work very well. The active ingredients are absorbed by the roots and distributed through the plant sap. As a result, the resistant animals absorb it and die.
- In the winter garden, mealybugs and mealybugs can be easily combated with beneficial insects that you can get from specialist retailers.
Aphids
Aphid infestations are rarely observed on palm trees. It is usually enough to shower the lice with a sharp jet. Only if the pests appear en masse should you treat the plant with a suitable insecticide.
Tip
Always isolate palm trees and other plants affected by pests from he althy houseplants. This means that the insects cannot spread excessively and the fight is quickly successful.
