Frost damage can be the cause of brown spots on the blue cypress
Why does the blue cypress become completely brown?
The blue cypress is often attracted to gardens because of its eye-catching appearance with its blue-colored needles. However, the evergreen trees do not look very nice if they get brown spots or even turn brown everywhere. Causes and prevention of brown spots.
Causes of a brown discoloration of the blue cypress
When planting choose a favorable location
To make sure that blue cypress trees grow up fast and healthy, they make sure that they feel comfortable at their location.
The woody plants like to have it sunny and warm. They do not like wind at all. Therefore, plant blue cypress trees in a sheltered place that will not be so cold in winter.
The soil should not be too dry or too humid. Waterlogging must be avoided in any case. Too moist locations favor diseases and pest infestation.
Avoid care mistakes
Although blue cypress trees are quite robust, they do not forgive care mistakes so quickly. Make sure the floor never completely dries up. In summer you have to water the blue cypress more often. But make sure that no waterlogging forms.
In the supply of nutrients tact is needed. The blue cypress tolerates neither a lack of food nor an oversupply of nutrients.
If you fertilize blue cypress trees with a special fake cyanosis fertilizer, follow the instructions. It is very beneficial if you regularly supply the cypress trees with mature compost. So you can not over-fertilize the plants.
Brown spots due to frost or environmental influences
Brown spots in spring indicate that the Blue Cypress has not weathered a cold winter so well. In this case, provide winter protection in the future.
Road salt and urine from dogs and cats does not tolerate the blue cypress. Therefore, you should never plant the trees directly on busy roads where salt is scattered in winter or animals regularly do business.
Tips
When cutting the blue cypress, make sure that you do not injure the old wood. The plant can not regenerate after such damage. The resulting brown spots disturb the appearance of the cypress in the long run.
