A new era for stone fruit trees

La irregularidad climática y el aumento de los costes de producción están acelerando la transformación del frutal de hueso en España y en el conjunto del arco mediterráneo. En este Climate irregularity and rising production costs are accelerating the transformation of stone fruit cultivation in Spain and across the Mediterranean basin. In this context, the sector is moving toward more efficient and technology‑driven models, where rootstocks and hedgerow‑based growing systems are becoming key tools to achieve productive stability and profitability.

In recent years, harvests have been marked by increasing volatility. Periods of high production have been followed by others with significant declines, conditioned by factors such as unstable weather, delays in vegetative development, or issues during flowering and fruit set. This alternation has reduced productive potential at different moments, although fruit quality has remained at stable levels.

This situation is not unique to Spain; it is repeated across many Mediterranean production areas, forcing growers to rethink their strategies and adopt systems capable of adapting to an increasingly uncertain environment.

The rootstock: from technical component to strategic decision

In this scenario, the rootstock has ceased to be a secondary factor and has become a key lever in farm management. Its influence is decisive in aspects such as vigor control, tree architecture, tolerance to water stress, or adaptation to different soil types, in addition to its role in plantation mechanization.

For Gerardo Brox Martínez, Head of Nurseries – Stone Fruit Division at Agromillora Spain, choosing the right rootstock is now “a decisive factor in a sector pressured by climate change and the continuous rise in production costs.”

Current trends point toward high‑performance clonal materials capable of offering a balance between productivity, resilience, and efficiency. In this field, solutions such as the Rootpac® series have gained prominence in high‑density orchards, especially in plum and peach.

Within this range, Rootpac® 20 stands out for its ability to enhance fruit size and quality, becoming a common choice in orchards focused on maximizing commercial value. Rootpac® 40, meanwhile, offers a balance between vigor and productivity, with good adaptation to different soil types, facilitating its use under diverse conditions. In more limiting situations, such as heavy soils or areas with drainage problems, Rootpac® R has shown particularly suitable performance, providing stability to the crop.

In the case of cherry, the Corette® series—developed in Michigan and produced by Agromillora—is enabling progress toward more efficient training systems, such as two‑dimensional models that simplify pruning, management, and harvesting. These rootstocks promote more controlled tree development and greater orchard uniformity, key aspects for mechanization and cost optimization.

This diversification allows growers to match plant material to the specific conditions of each farm, optimizing both yield and agronomic management.

The hedgerow system drives a shift in the production model

At the same time, stone fruit production is undergoing a paradigm shift toward more intensive systems, with hedgerow cultivation emerging as one of the most efficient alternatives.

This model increases productivity per hectare, improves fruit quality, and significantly reduces labor costs thanks to its high compatibility with mechanization. It also provides greater uniformity across the orchard and optimizes the use of resources such as water and inputs.

Reducing dependence on labor has become one of the main drivers of its adoption, in a context of growing scarcity of specialized field workers.

The development of specific rootstocks has been essential for the expansion of this system, ensuring homogeneous crop behavior, promoting early production, and adapting to narrower planting distances.

Keys to future competitiveness

Looking ahead, the stone fruit sector faces the challenge of consolidating this modernization process. Genetic improvement—both in rootstocks and varieties—orchard renewal, and the professionalization of production structures will be decisive factors.

Added to this is the need to adapt to an increasingly demanding regulatory framework and to a market that prioritizes not only organoleptic quality but also supply consistency.

In this new scenario, differentiation will no longer depend solely on the cultivated variety, but on the ability of farms to integrate innovation, mechanization, and efficiency into their production model. A structural shift that will shape the future of stone fruit cultivation in the Mediterranean.
