How to counteract it (palm lily)

Recognize and treat a lice infestation

The various plant lice are sucking pests that prefer to sit on the underside of the leaves and pierce the veins there. In the case of the yucca, an infestation often only shows up in a strange way sticky leavesThe soil below the plant can also be covered with a sticky mass. Furthermore, deformations on leaves and shoots, spots, traces of eating or poor growth provide valuable information. The animals themselves are often very difficult to recognize - their tiny size ensures that they remain undetected for a long time. The pests can be combated in different ways, whereby the poison bottle should only be reached if nothing else helps:

• Wiping off or showering (for aphids)
• remove infested leaves and shoots (in the case of a slight infestation)
• Spray the infested plant with a mixture of tea tree oil and water (10 drops on one liter of water, very good for scale insects and mealybugs)
• Wipe off the infected plant with rinse water (a few drops of detergent such as Pril etc. in lukewarm water)

Which lice prefer to settle on the yucca?

The following three types of plant lice are particularly common on the yucca. Separate infested plants immediately to prevent them from spreading.

Scale insects

The tiny scale insects are on the brownish, hard "shells" - they can see with bare eyes eye more like small brown "eggs" - to be recognized. They can be combated well with biological agents based on oil (e.g. rapeseed or tea tree oil).

Mealybug

Mealybugs or mealybugs are surrounded by cotton-wool-like, whitish wax excretions. Again, you should dab the affected areas with tea tree oil or spray the infected plant with a solution based on tea tree oil.

Aphids

Aphids can be green, yellow, brown or black and mainly attack the soft parts of the plant such as young leaves and shoot tips. Shower the infected plant thoroughly and spray it with a tea tree or lavender oil-based solution.
