On May 27th, the second session was led by Pietro Tonini, who holds a PhD in Environmental Science and Technology (UAB) and is a specialist in horticultural sciences and agribusiness, with a focus on food systems and sustainable consumption. This time, the session took on a more practical dimension, with the expert visiting the urban garden where the activities have been taking place, aiming to deepen understanding of best practices in the field.

The session focused on key topics such as crop associations and rotations, pest and disease prevention and treatment, as well as the planting of ornamental and horticultural species. All participants had the chance to enjoy an afternoon dedicated to hands-on learning.

The activity began with a theoretical component, essential to provide context and explain the importance of each subject discussed. Topics included different types of soil and how to work with them properly, what to plant in each season and why, and the varying water needs of different crops.

With the theory covered, it was time to put knowledge into practice: participants built a raised garden bed, a technique used to improve drainage and allow roots more space to grow. In it, they planted flowers designed to attract beneficial insects that help protect the garden from pests.

Throughout the activity, participants learned each step of the process, with clear explanations about the reasoning behind every action. In addition, Pietro addressed key concepts such as the importance of crop rotation, different types of crops, and various other useful tools for effective and sustainable garden management.

Once again, it was a highly enriching afternoon at the Parc de les Olors, giving participants the valuable opportunity to learn directly from an expert in the field.
