Which diseases and pests occur in camellias?
Camellias are quite robust potted plants. Diseases are almost exclusively responsible for care errors. Even a pest infestation, which occurs occasionally, can hardly really harm a well-groomed Camellia japonica. Which diseases and pests of camellia are causing problems.

Only one disease is really dangerous to the camellia. Other abnormalities are not diseases, but symptoms that indicate an incorrect location or care:
What you can do about camellia plague
The Camellia plague has only recently occurred in Europe. They recognize the disease because the flowers rot from the inside and fall off after a few days. Always cut off rotting buds and dispose of them with household waste.
Rotten or deciduous leaves and flowers
A camellia leaf grows on the plant for about three years and then drops off. That is normal. Only when buds and leaves frequently fall off or rot, something is wrong. These are almost always nursing mistakes. The cause may be a too dark or too warm location, too much or too little moisture or a calcareous soil.
Affected plant parts are cut out. Make the Camellia japonica bright enough, but avoid too much sunlight. Check the plant substrate if it contains enough nutrients. Sometimes it is enough to repot the plant in fresh potting soil.
Water only moderately from late summer and avoid waterlogging during the rest of the time. Give liquid flower fertilizer without lime according to instructions.
Pests that can occur in camellias
The larvae of the weeping weevil can cause lasting damage to the camellia. If the beetle occurs, you should search the soil well and remove all larvae.
Scale insects can be rinsed off with a powerful jet of water. For example, soap broths or, as natural enemies, lacewings and ladybirds help against thrips.
Tips & Tricks
Nematodes, small roundworms, are also suitable for the biological control of weeping beetles and thrips. They eat up the pest larvae from the inside and destroy them. Nematodes are available from specialist retailers.
