The columnar cypress - due to its origin also known as Mediterranean or Tuscany cypress - is a very slender, upright tree that is often planted as a hedge or as a solitary tree in our latitudes. However, Cupressus sempervirens, as it is called scientifically, is only partially hardy and is also very difficult to care for.
The larger the columnar cypress, the less maintenance they need
How much water do columnar cypresses need?
It is particularly complicated to supply the columnar cypress with sufficient water. The evergreen conifer does not tolerate wetness or constant moisture or drought - finding the right middle ground is sometimes not that easy. Columnar cypresses also need a drainage layer made of coarse gravel in rather damp locations in the garden, for example, but should be watered from time to time in rather dry locations, even in winter.
Do you have to fertilize columnar cypresses?
In the first year you do not need to fertilize the plant, but after that it is advisable to give slow-release fertilizer every year in late spring or alternatively to give conifer fertilizer regularly. Blue grain (twice a year in spring and summer) and horn shavings (€32.93) are also very good for nutrient supply.
When and how should you prune columnar cypress?
Columnar cypresses naturally strive for their slender, columnar growth, so that pruning is basically not necessary. However, an annual pruning makes sense to counteract a balding. However, the shrubs are very tolerant of pruning, so that regular pruning and pruning do not pose a problem.
What signs of disease should one look out for in columnar cypresses?
Columnar cypresses are preferentially attacked by bark beetles, leaf miners, tree lice (which are understood to mean various types of specialized aphids), mealybugs and other pests. Check the plants regularly for signs and take countermeasures in good time. You should prefer the use of biological agents to chemical ones.
What to do if the columnar cypress sheds its needles or they turn brown?
Brown spots often form due to lack of water and do not go away. In such a case, only a pruning helps so that the plant drives out again. Epsom salts often help with brown needles.
Are columnar cypresses hardy?
Columnar cypresses are only partially hardy and therefore cannot be planted out in regions with severe winters, where they require excellent winter protection.

Alternatively, the Mediterranean plants can also be cultivated in large tubs, but in this case they require regular care. Above all, the substrate must neither be too dry nor permanently damp.
