Does a leaf spot come back?

Leaf Spot

Leaf spots can recur if conditions remain favourable for the pathogens that cause it, such as high humidity and poor air circulation. The persistence of spores in the soil or on plant debris can also facilitate the return of the disease each season. Preventative measures such as crop rotation, plant debris removal, and proper sanitation of gardening tools can help minimize the risk of recurrence. Using resistant plant varieties and adjusting cultural practices like watering and pruning can also reduce the incidence of leaf spots. Regular tree spraying with fungicides during susceptible periods can help keep the disease at bay, especially for high-value ornamental or crop plants.
