Portuguese cherry laurel, Prunus lusitanica - care: cherry

The Prunus lusitanica belongs to the plant family of the rose family. He is undemanding and forms a dense growth with time. As a heat-loving ornamental shrub, the Portuguese cherry laurel is extremely hardy and tolerates temperatures down to minus 20° C. On the other hand, it withstands extremely high temperatures and copes well with short periods of drought. The attractive flower clusters immerse the foliage of the Portuguese princess in a creamy white sea of ​​flowers. The hedge plant is similar to the true laurel, but is not related to him.

Origin and appearance

As the name suggests, the Portuguese wood is native to the Azores and Canary Islands, the Iberian Peninsula and southwest France. There she seeks sunny locations in juniper forests and crater canyons. However, the pure wild form can now be found almost nowhere. The Mediterranean plant derives its name from the Roman province of Lusitanica (today's Portugal).
Prunuslusitanica reaches a stature height of up to four meters in the home garden and occupies a width of up to two and a half meters in width. Depending on location and pruning, the plant grows in size from 20 to 35 cm in a year. The bushy and upright shrub shows its new shoots in a handsome red tone. The glossy leaves are leathery, dark green, ovate pointed and provided with a showy red petiole. The creamy white flowers stand upright and produce egg-shaped, dark-red drupes. The plant is well suited as a hedge can be cultivated as a container plant just as well.

Location

To find the optimal location for the Mediterranean plant, it requires no great effort, as it is quite undemanding. Due to its origin, it is sun-drenched and therefore thrives best on a sunny to partially shaded spot. Although the Portuguese princess is heat-tolerant, it should be protected from the chilly east wind.

substratum

Also on the soil conditions, this variety of cherry orchards, which is all too happy with countless small white flower clusters, no special claims. Basically, the plant prefers a loose and well-drained soil. Such a soil ensures that no waterlogging in the roots can accumulate. Because waterlogging permanently damages the well-being of Prunus lusitanica. It is also advantageous if the wood is set in sandy-clayey, gritty-loamy or sandy-loamy soil.
Tip: To highlight the benefits of this plant, we recommend a nutrient-rich, slightly acidic to strongly alkaline soil.

to water

It has a positive effect on the appearance and the growth of the Mediterranean beauty, when it is poured less frequently but penetratingly. Thorough watering stimulates the roots of the plant to reach deeper layers of soil, thus surviving short dry spells.
Tip: In order to prevent fungal diseases, really should only be poured when the surface is dried out.

Fertilize

Basically, the Portuguese cherry laurel does not have to be fertilized. The ornamental shrub is well supplied for the first time, if when planting manure, horn chips or compost are introduced into the soil. Furthermore, commercial liquid fertilizer can be used so that the shrub is sufficiently supplied with nutrients. Fertilization will be discontinued from August, as otherwise too many new shoots will form that are sensitive to the coming cold.

overwinter

Although the Prunus lusitanica can tolerate temperatures down to -20° C, the root area should not only be covered in young plants. For covering fir branches and leaves are suitable. An additional layer of mulch provides the Portuguese laurel with nutrients. Delicate little bushes, which have their first winter in front, are looking forward to a protection from branches. As evergreen wood, the cherry laurel needs sufficient water even in winter. Otherwise it reacts after the winter months with brown leaves. However, it is only poured on frost-free days.

To cut

Basically, the Prunus lusitanica can be cut back all year round - except in frosty weather and on hot summer days. The cutting takes place after the flowering period. The shoots are cut five to ten centimeters. This has the advantage that the plant thrives better and shows itself in full bloom in the next year. Of course, the shoot tips can also be trimmed in between. This creates more branches. For cutting, the mechanical hedge trimmer is recommended. An electric hedge trimmer can leave brown edges on the leaves.

planting time

In case of dryness, ensure that there is sufficient irrigation. The planting hole should be twice as big as the bale. Horny shavings, manure or compost can be used as long-term fertilizer. There are no more than three plants placed on a meter in the ground. Finally, water well.
