The blue cypress is often grown in gardens precisely because of its striking appearance with its blue-colored needles. However, the evergreen trees don't look very nice if they get brown spots or even turn brown all over. Causes and prevention of brown spots.
Why is my Blue Cypress turning brown?
Blue Cypresses turn brown when they suffer from drought, wetness, lack or excess of fertilizer, frost damage or environmental influences. A suitable choice of location, correct irrigation and fertilization as well as winter protection can prevent such brown discoloration.
Causes of brown discoloration of the blue cypress
- Too dry
- Too wet
- Too much fertilizer
- Too little fertilizer
- Frost Damage
- Environmental influences
Choose a favorable location when planting
So that blue cypresses grow quickly and he althily, make sure that they feel comfortable in their location.
The trees prefer sunny and warm. They don't like wind at all. Therefore, plant blue cypresses in a protected place where it doesn't get so cold even in winter.
The soil should not be too dry and not too moist. Waterlogging must be avoided in any case. Locations that are too wet promote diseases and pest infestation.
Avoid care errors
Blue cypresses are quite robust, but they are not so quick to forgive care mistakes. Make sure the soil never dries out completely. In summer you have to water the blue cypress more often. But make sure that there is no waterlogging.
Tact is required when supplying nutrients. The blue cypress can neither tolerate a lack of nutrition nor an excess of nutrients.
If you fertilize blue cypresses with a special cypress fertilizer (€17.00 on Amazon), follow the instructions. It is very beneficial if you regularly supply the false cypresses with ripe compost. This means you can't over-fertilize the plants.
Brown spots due to frost or environmental influences
Brown spots in spring indicate that the blue cypress did not survive a cold winter so well. In this case, ensure winter protection in the future.
The blue cypress does not tolerate road s alt and urine from dogs and cats. That's why you should never plant the trees directly on busy roads where s alt is spread in winter or where animals regularly do their business.
Tip
When cutting the blue cypress, be careful not to damage the old wood. The plant cannot regenerate after such damage. The resulting brown areas disturb the appearance of the false cypress in the long term.
