Prunus lusitanica, commonly known as the Portuguese laurel, is a broadleaf evergreen tree or large shrub native to southwestern France, Spain, Portugal, and Morocco. It is known for its glossy, dark green leaves and fragrant white flowers that bloom in late spring. The plant can grow up to 15 meters tall and is often used for hedging and screening. It has a dormancy period during the winter months.
Prunus lusitanica thrives in full sun to partial shade and prefers moderate temperatures. It requires regular watering, especially during dry periods, but can tolerate some drought once established. The plant benefits from moderate humidity and should be protected from extreme cold.
土壤
The Portuguese laurel prefers well-drained loamy soil but can tolerate a range of soil types, including clay and sandy soils. It is important to ensure good drainage to prevent root rot. The soil should be kept moderately moist but not waterlogged.
肥料
Fertilize Prunus lusitanica in early spring with a balanced fertilizer, such as 10-10-10, to promote healthy growth. Apply the fertilizer according to the manufacturer's instructions, and avoid over-fertilizing, which can harm the plant.
换盆
If growing in a container, repot Prunus lusitanica every 2-3 years or when the plant becomes root-bound. Choose a pot that is slightly larger than the current one and use fresh, well-draining soil. Repotting is best done in early spring before new growth begins.
传播
Prunus lusitanica can be propagated by semi-hardwood cuttings taken in late summer or early autumn. Dip the cuttings in rooting hormone and plant them in a well-draining soil mix. Keep the cuttings in a humid environment until roots develop.
修剪
Prune Prunus lusitanica in late winter or early spring to maintain its shape and remove any dead or damaged branches. Regular pruning helps to promote dense growth and can be used to control the size of the plant.
毒性
Prunus lusitanica is toxic to pets and humans if ingested. The leaves, seeds, and bark contain cyanogenic glycosides, which can release cyanide when chewed or digested. Symptoms of poisoning include difficulty breathing, vomiting, and seizures. Keep the plant out of reach of children and pets.
