It is important that frost control begins on the day of application of the dormancy breaker (hydrogen cyanamide or budbreak uniformity product), regardless of the frost control system used.
)
Frost damage occurs when nucleation begins, namely the intracellular formation of ice crystals. With the preventive application of products capable of lowering the freezing point of tissues, the aim is to delay intracellular nucleation and reduce its triggering temperature, as well as to improve cell membrane stability and repair before, during and after the event.
These tools make it possible to prevent, mitigate and repair damage caused by low temperatures.
)
After a frost event, it is necessary to carry out disease control treatments. It should be considered that we are in the stages when the cherry tree is most susceptible to diseases, particularly bacterial canker.
During this period, several risk factors coincide: the increase in the Pseudomonas population, the presence of free water, frost events and the progressive opening of plant tissues, which makes plants even more vulnerable to disease pressure.
Therefore, after these rainfall events, it is necessary to adopt the appropriate management practices to preserve the health status of orchards.

A recent study from Portugal and Denmark focused on the effects of two biostimulants: glycine betaine and an extract derived from the seaweed Ecklonia maxima. These biostimulants were applied to sweet cherry cultivars “Early Bigi” and “Lapins” grafted onto SL-64 rootstock.

Cherry growers have at their disposal dwarfing or semi-dwarfing rootstocks, suitable for high-density planting patterns, which can ensure an early entry into production, excellent production efficiency and good cherry quality.

Chile forecasts 727,000 tonnes of cherries in 2026/27, with around 20% of the crop potentially destined for processing. The record harvest could boost supplies of IQF frozen, sulfited and dried cherries as exporters diversify beyond Chinese market and other destinations.

In Armenia, Naughty Orchards grows early cherries on 80 ha using Italian varieties Carmen, Sweet Gabriel and Sweet Lorenz. Following its first major harvest in 2026, the company targets 2,000 tonnes and export markets across Europe and the Gulf, with its own cold chain.
