The rubber tree is quite robust and quite easy to care for. This means it doesn't suffer from pests or diseases too often. However, there are a few things you should keep in mind to ensure that your houseplant stays he althy for a long time and always grows well.
What diseases and pests can affect rubber trees?
Rubber trees can be attacked by spider mites and mealybugs. Spider mite infestations are visible through fine webs, while mealybugs are noticeable through oil stains. Sufficient light, humidity and temperatures above 16 °C help preventatively. In case of infestation, spraying with water and using lacewings or predatory mites helps.
Mealybugs or spider mites occasionally appear, especially during the heating season. The infection is quite easy to recognize on the dark green leaves. The indoor climate is often to blame. Air that is too dry and too warm promotes an infestation.
How can I help my sick rubber tree?
Discover the fine web of the spider mite, then shower your rubber tree with a powerful jet of water. Then cover the entire plant with a clear plastic wrap or bag. The spider mites don't like the moisture created in it at all. You can also use lacewings to combat these annoying little creatures.
You can fight mealybugs with a mixture of oil, dish soap and water, or alternatively with predatory mites. To ensure that no other plants are infected, you should definitely isolate the affected rubber tree. When repotting afterwards, examine the root ball for larvae or eggs.
To prevent pest infestation from occurring in the first place, increase the humidity. Either spray the leaves of your rubber tree with lime-free water from time to time or place a humidifier near the plant. Wiping with a damp cloth is also helpful.
How can I prevent diseases in the rubber tree?
The best way to prevent diseases and pests is to place your rubber tree in a suitable location and take good care of it. The rubber tree likes it warm; it does not tolerate temperatures below 16 °C well during the growing season. In winter it can be a little cooler. However, it needs a lot of light all year round.
The best preventative measures:
- lots of light
- water enough but not too much
- Avoid waterlogging
- Time for hibernation at the right temperature
- Room temperature never below 16 °C
Tip
Always check your rubber tree for any diseases or pest infestation when watering, then you can react immediately.
