Frost resistance of cherry laurel

Prunus laurocerasus L.

The frost resistance of cherry laurel determines the survival limit of tissues at sub-zero temperatures, varying from -15°C to -27°C depending on the genotype. The main criterion is the LT50 index, which reflects the temperature causing death or damage to 50% of plant tissues.

In the reference 3 varieties crop Cherry laurel, where this is mentioned in the description.

The frost resistance of cherry laurel (Prunus laurocerasus) is quantified using the LT50 index, which identifies the threshold of tissue damage under extreme temperatures. Exceeding this limit results in visually observable browning and leaf drop, cambium damage, and potential death of the entire plant. For cultivars of this species, the range of critical temperatures varies from -15...-17°C for less hardy forms to -25...-27°C for the most acclimated genotypes.

The agrotechnical assessment of frost resistance is closely linked to the plant's hardening process and growing conditions. In regions with severe winters, cherry laurel may lose its evergreen status, partially shedding its canopy. To improve survival, protection against desiccating winter winds and sunscald is critical, as well as adherence to a water regime that prevents excessive growth before the onset of cold weather.
