The mussel cypress is a little tricky when it comes to location and care. In an unfavorable, cool place with too much moisture, it suffers more often from diseases or pest infestation. How to recognize diseases and what you can do about them.

The mussel cypress is rotting - what to do?
If the mussel cypress suffers from root rot, you will recognize this by the fact that the shoots become soft and discolored. Often there are small black dots on the needles, in which fungal spores hide.
The causes of clam cypress rot are almost always waterlogging and excessively cool temperatures. The plant must never dry out completely, but standing wetness is its downfall.
Take a mussel cypress affected by rot from the pot and rinse the plant substrate completely. Cut off rotten roots and shoots generously and dispose of them with household waste. Then place the tree in fresh plant substrate.
Brown leaves on the mussel cypress
Brown leaves inside the clam cypress are normal and not a sign of disease. If young needles turn brown on the outside, wetness and a location that is too cool can also be responsible.
Cut off affected parts and discard.
What pests do you need to watch out for?
Not very often but occasionally some pests of the mussel cypress cause problems:
- aphids
- leaf miners
- mites
You should treat an infestation as soon as possible. The longer you wait, the more serious the damage that the pests cause.
For small trees, wash off all affected parts of the plant with diluted soft soap (44.90€). In the case of larger specimens, only the use of pesticides often helps.
disease prevention
You can prevent diseases of mussel cypresses by caring for the plant in a good location. It should be bright and like to be sunny. The mussel cypress only likes it a little cooler in winter.
If possible, water regularly with rainwater only, because mussel cypresses do not tolerate lime well. In winter there is less watering.
tips
Mussel cypresses do not like it cool. The ideal temperature in summer is above 20 degrees. In winter, most varieties must be overwintered frost-free at at least five degrees.
