This article, written exclusively for Cherry Times readers by Jesús Alonso, a Spanish researcher and member of the scientific committee of this magazine, examines the physiological and agronomic factors that determine orchard establishment, fruit quality and production stability in sweet cherry (Prunus avium L.) cultivation models intended for cherry production for the fresh market.
The central thesis is that marketable production does not depend on a single cultivation practice, but rather on an integrated sequence that begins in the previous production cycle with floral induction and the formation of flower buds; continues through the fulfilment of the winter chilling requirement, spring heat accumulation, flowering, pollination and fruit set; and culminates in the stages of fruit growth, ripening and harvesting.
The article, divided into two parts, integrates several aspects:
The approach adopted connects physiological mechanisms with agronomic evidence to support context-specific technical decisions, avoiding the transformation of thermal models, critical thresholds or cultivation interventions into universal prescriptions.
Sweet cherry (Prunus avium L.) is a high-value temperate fruit crop whose profitability in fresh-market systems depends on tight coordination among climate, phenology, and orchard management. Commercial production requires trees to enter bloom with well-formed flower buds, to have satisfied their winter chilling requirement, to accumulate spring heat sufficiently and uniformly, to maintain favorable conditions for pollination and fruit set, and to complete fruit development under a balanced integration of water supply, nutrition, crop load, canopy architecture, and climate-risk mitigation (Fadón et al., 2021; Fadón et al., 2023; Hedhly et al., 2004; Wani et al., 2014).

When developing a fertilisation programme, it is necessary to determine what nutrients the crop needs and when it needs them. A simple approach is to define the needs of the trees and the crop based on the estimated yield.

From snowy Montana comes the new “FE” cherry, cold-hardy to -45°C and ideal for pies, wine, preserves, and fresh eating. Backed by 60 years of family-driven selection, it’s now available from HoneyberryUSA, a leader in American cold-hardy fruit farming.

Strigolactones strengthen postharvest defenses in sweet cherries against Botrytis cinerea. Research on the Xianfeng cultivar shows that 0.1 μM reduces gray mold, lesion development and fungal biomass by activating phenylpropanoids, flavonoids and defense proteins.

Managing frost damage in cherry trees requires action from dormancy breaking through vegetative growth. Preventing ice nucleation, protecting cell membranes, and controlling Pseudomonas and bacterial canker can help preserve orchard health, resilience, and productivity.
