Cultivated in the best conditions, a Cypress can reach a beautiful height, some varieties being able to reach 25 meters. It is a very graphic tree that evokes Mediterranean landscapes. It does not pose any particular problem, which is why it is ideal for inexperienced gardeners. Be careful, however, its pollen is allergenic. Let’s take stock of the plantation of this beautiful coniferous, its maintenance and the different possible uses.
Plant a Cypress
The best time to plant a Cypress is early fall, when the ground is warm and the first frosts are not yet present. To plant a Cypress, proceed as follows:
- Soak the root ball for a good hour in a large basin of water so that it rehydrates,
- Dig a hole 2 to 2.5 times larger than the root ball,
- Sift the garden soil extracted then mix it with peat and some powdered horn because the Cypress needs an organic fertilizer rich in nitrogen and slowly diffusing,
- Place a layer of stones at the bottom of the planting hole in order to create a draining bottom, a precaution all the more important if the Cypress is installed in a heavy and clayey soil which tends to retain water,
- Cover this drainage layer with about 50 or 60 cm of the stored mixture,
- Install the cypress foot in the center of the hole,
- Untangle the root bun then spread the roots without damaging them,
- Fill in with the rest of the earth / soil / crushed horn mixture,
- Firmly pack the earth by holding the tree so that it remains perfectly straight,
- Form a bowl at the foot,
- Water enough.
Afterwards, care must be taken to ensure that the soil retains a certain freshness in order to allow the cypress to take root.
Cypress is ideal for a isolated use. But you can also choose to cultivate several Cypress trees in order to create a privacy hedge and windbreak very efficient while bringing an aesthetic touch to the property. In this case, we must dig a trench 45 or 50 cm wide and 60 to 70 cm deep, and we plant the cypress trees, taking care to separate them by about 1.50 m from each other.
Undemanding, the Cypress tolerates any type of soil since it is well drained because its roots must not bathe in water. He especially likes to be installed in broad daylight.
Caring for the Cypress
Any gardener, even a beginner, can plant a Cypress because this beautiful tree does not have great demands.
During the three years which follow the plantation of a Cypress, it is necessary to take care of the waterings which must be regular but not excessive. Be careful especially in the event of a scorching summer. If the young conifer lacks water, it stops growing and you can see the yellowing of its scaly foliage, that is to say in the form of scales.
After three years, except in the event of severe and persistent drought, it will no longer be necessary to water the Cypress because its roots will be able to draw water in depth. Obviously, for the subjects grown in pots, it is necessary to water regularly throughout the summer, but again without excess because it is necessary to avoid any risk of stagnant water very detrimental to the Cypress.
During the first years after planting, it is recommended to do in may or june additions of complete fertilizers to support the growth of the Cypress. Nettle manure, crushed horn, bone powder are quite suitable.
A cypress planted in isolation does not need to be pruned. On the other hand, the size is necessary for a cypress hedge having reached the desired height, and must be carried out annually in the month of September, these trees showing relatively rapid growth. Be careful, however, not to cut old wood but only young branches and of course the dead branches.
Pruning a large cypress requires precautions to ensure the security, whether one is obliged to climb on a stepladder or a ladder. The good idea is to get information from a landscape professional in order to entrust him with the pruning of the Cypress trees.
Parasites and diseases
The most common pests found on cypress trees are aphid, the thuja bupreste, the cochineal and thered spider. We can naturally fight against these undesirable by adopting preventive and / or curative methods such as ladybird larvae and nettle manure spray, a decoction of pyrethrum or even a drench of the foliage. Severely infested parts should be removed and then burned.
Excess humidity can be responsible for cryptogamic diseases. This is also the case if several cypress trees are planted too close to each other because the air circulates poorly between the trees. Precautions must therefore be taken to protect them from diseases such as, for example, installing them in well-draining soil, using horsetail sprays on the aerial parts and pulling up diseased trees, absolutely avoiding replanting others in the same place. . Obviously, this type of disease is treated with suitable fungicides.
When buying a Cypress (conifer of the family of Cupressaceae), it is advisable to be well informed about its peculiarities because there are some different species such as the Leyland Cypress (2 to 10 m), the Tuscan Cypress (6 to 8 m) or the Provence Cypress (10 m), the very original Cashmere Cypress with its weeping habit (6 to 18 m) ) or also the Lambert Cypress (up to 25 m) …
If the adult height matters a lot, thespan of the tree is also decisive. The choice therefore depends on the area of the land but also on the use of these conifers. Those with great development are rather intended for an isolated plantation, and one opts for those with weak development if one wishes to create a cypress hedge.
