Pruning in olive groves. Remove all the bad and keep the good

One of the key tasks we carry out once the cold winter weather has passed is pruning our olive grove. Normally, we begin this process in March, but this year, thanks to the abundant rainfall, we had to start, a little later, almost in April.

In this post we would like to share a brief summary of our pruning work, as well as comment on some tips and things to bear in mind when pruning olive trees. It can basically be summed up as ‘remove all the bad and keep the good”. But how do you know what to remove and what to keep? Each tree tells you.

First, it's important to understand the type of pruning you’re going to perform. Not all pruning is the same:

  • Creation (training) pruning for young olive trees.
  • Thinning pruning for trees in full production.
  • Renewal pruning for older olive trees.

In our case, we’ll focus on training and thinning pruning.

We apply creation pruning to olive trees up to six years old, with the goal of preparing them for mechanised harvesting using umbrellas.

The key objectives are:

  • Raise the main structure (cross) to a height that allows the harvesting machine to operate without interference.
  • Prevent lower branches from touching the canvas of the umbrella.
  • Structure the cross with two or three main branches.

This type of pruning is applied to olive trees over six years old and aims to maintain a balanced leaf-to-wood ratio.

Our main tasks include:

  • Removing excess wood (especially thick branches) to encourage more leaf growth, which is essential for olive production.
  • Eliminating vertical branches ("males") in favor of horizontal ones ("females"), which are more productive.
  • Observing the tree’s natural structure—because, as we always say, “the tree tells you what to cut”.

Some of the things to be considered in all types of pruning could be:

The olive tree must be well tucked in, i.e. it must not lose its leaves.

  • Pruning is based on removing what is left over to leave what is good, i.e. removing the ‘bad branches’ to leave the ‘good branches’.
  • Small branches should not be removed, i.e. thick branches should not be ‘sanded’.
  • Pruning varies according to the variety of olive tree.
    • A picual olive tree wants to be pruned aggressively to remove thick branches as it is a variety that tends to generate a lot of wood.
    • A white-leaved olive tree wants a less aggressive pruning to remove less wood as it is a variety with a fine wood structure.

To conclude, pruning is essential for maintaining productive and healthy olive trees. Whether training young trees or thinning mature ones, the goal is always the same: remove the unnecessary to strengthen what matters—and let each tree guide your hand.

GO OLIVITECH: Precision Technology for Sustainable Olive Growing

Olive growing faces major challenges due to climate change and the increasing demand for sustainable and profitable production. One of the main issues affecting olive groves is the efficient management of fungal diseases.

Traditionally, the approach to combating these diseases has been the application of phytosanitary treatments, which imply a high economic cost and a significant environmental impact (for example, we usually apply four treatments during the year). However, the digitalisation of agriculture opens a new era, not only in production management, but also in the phytosanitary management of olive groves.

This is where GO OLIVITECH comes into play. Its goal is to revolutionise plant health management in olive groves through the use of automatic aerobiological sensors, big data analysis and predictive models. By anticipating the emergence of diseases, OLIVITECH aims to optimise phytosanitary treatments.

How does OLIVITECH work?

The system developed by OLIVITECH integrates meteorological, aerobiological and phenological data to establish a predictive model of the evolution of diseases in olive groves. Its technical approach is based on three fundamental pillars:

Real-Time Monitoring with Aerobiological Collectors

  • The samplers collect air samples and identify spores of key pathogens.

Phenological and Meteorological Data Integration

In addition to aerobiological information, OLIVITECH incorporates data on:

  • Olive Phenology: Analyses the different stages of crop development to identify critical periods of susceptibility to diseases.
  • Weather Conditions: Monitors temperature, relative humidity and precipitation, which are key factors in the spread of fungal pathogens.
  • Symptomatology History: Assesses disease occurences from previous campaigns to improve the accuracy of the predictive model.

Predictive Modelling and Early Warning Tools

All the information collected is processed using data mining and machine learning algorithms, enabling:

  • Prediction of fungal attacks one week in advance.
  • Identification of critical sporulation thresholds to recommend or rule out treatments.
  • Optimisation of pesticides use, reducing unnecessary applications.

In our experience, having a personalised alert system gives us a new level of insight into the crop, allowing us to take action at the right time and avoid unnecessary treatments.

Technical and economic benefits of OLIVITECH

If we focus on an economic and environmental point of view, we can highlight the following:

  1. Reduced Production Costs
    • Fewer chemical treatments.
    • Reduced working hours and use of machinery.
    • Improved efficiency in the application of treatments.
  2. Enhanced Sustainability and Regulatory Compliance
    • Lower pollution of water, soil, and air due to reduced use of phytosanitary products.
    • Supports production under ecological criteria.
    • Lower environmental impact and better alignment with the Common Agricultural Policy (CAP) 2023-2027.
  3. Improved Competitiveness of the Olive Sector
    • Advanced management tool based on precision agriculture.
    • Greater resulience to climate change and emerging phytosanitary threats.
    • Increased profitability and access to new export markets.

Who is involved in the OLIVITECH project?

The OLIVITECH Task Force is made up of a consortium of entities from different fields:

Funding and institutional support

OLIVITECH is an innovation project within the framework of the Strategic Plan of the Common Agricultural Policy (PEPAC) 2023-2027, 80% financed by the European Agricultural Fund for Rural Development (EAFRD) of the European Union and 20% by the Ministry of Agriculture, Fisheries and Food (MAPA), with a total budget of €551,196.27 and a total grant of €543,206.47.

Conclusion: A More Precise Future for Olive Groves

The advancement of precision agriculture and the integration of aerobiological technology with predictive models allow us to evolve towards more efficient and sustainable disease control. Undoubtedly, we will have more tools to make management much more efficient as we can make decisions based on real data. 

By making data-driven decisions through a more efficient management. We can minimise costs and environmental impacts based on real data without compromising olive oil production and quality.

Olive harvest 2024

With this year's olive harvest complete, we can confidently say that the season has been good in general terms. The production volume has been abundant, thanks to consistent rainfall throughout the year, which helped the olives replenish their water reserves. Additionally , the olive trees that we had to cut back due to Filomena (as they froze) have started producing again this year. Furthermore, the oil yield has been quite good (around 18% on average), which will be reflected in the quality of the oil and the earnings from the delivered olives.

Harvesting is done manually using Sthil shakers, as the trees currently have a small structure (thin trunks) and the older olive trees have multiple trunks, leaving us with limited mechanization options. However, if growth continues at its current pace, we are already considering mechanized harvesting next year with umbrella harvesters. We will monitor how the olive trees develop throughout 2025 and we will keep you posted.

Regarding the oil mill, we continue delivering our entire production to the Nuestro Nazareno Cooperative (Sisante - Cuenca), where we have been members for many years. The cooperative has consistently provided us with good profits and produces fantastic olive oil.

Finally, we would like to wish you a happy and prosperous year 2025. May the coming year bring health and bountiful harvests.... with that, farmers will be unstoppable!
