SloveniaA reader wrote to ask whether a walnut tree under her cherry and plum trees might be causing their health issues. The tree was thriving in spring but later experienced rotting fruit clusters and drying branches. She had been using copper-based fungicides and aerating the soil under the canopy. An agricultural expert responded that the walnut tree is not the cause of the problems. Instead, the symptoms suggest a severe infection by moniliosis, a fungal disease. Moniliosis affects both flowers and fruits, spreading quickly in tight clusters like those on cherries and plums. Infected fruits dry out into 'mummies' that become a major source of reinfection. The expert recommends removing all infected fruits and branches, avoiding composting them at home, pruning affected areas in dry summer conditions, and applying compost in spring rather than directly around the trunk.
