Choose a favorable location when planting
In order for blue cypresses to grow quickly and healthily, make sure that they feel comfortable in their location.
The trees like it sunny and warm. They don't like wind at all. Therefore, plant blue cypresses in a sheltered place where it doesn't get that cold even in winter.
The soil should not be too dry and not too wet. Waterlogging must be avoided in any case. Locations that are too damp encourage disease and pest infestation.
Avoid care mistakes
Although blue cypresses are quite robust, they do not forgive care mistakes so quickly. Make sure the soil never dries out completely. In summer you have to water the blue cypress more often. But make sure that no waterlogging forms.
Delicacy is required when supplying the nutrients. The blue cypress tolerates neither a lack of food nor an oversupply of nutrients.
If you fertilize blue cypress trees with a special cypress fertilizer, follow the instructions. It is very beneficial if you regularly supply the cypresses with mature compost. With this, you cannot over-fertilize the plants.
Brown spots due to frost or environmental influences
Brown spots in spring indicate that the blue cypress has not survived a cold winter so well. In this case, provide winter protection in the future.
The blue cypress does not tolerate road salt and urine from dogs and cats. Therefore, you should never plant the shrubs directly on busy roads where salt is spread in winter or where animals regularly do their business.
tips
When cutting the blue cypress, be careful not to damage the old wood. The plant cannot regenerate after such damage. The areas that have become brown as a result disturb the appearance of the false cypress in the long term.
