When are leaf spots most commonly seen?

Leaf spots are most commonly seen during early spring and fall due to environmental conditions that are conducive to the development of fungal and bacterial infections. In early spring, as temperatures begin to rise and moisture levels may fluctuate due to rain, plants are more susceptible to these infections which can lead to spotting on leaves. Similarly, fall often brings wet conditions accompanied by cooling temperatures, creating an environment favorable for pathogens that cause leaf spots.

These seasonal factors, such as increased humidity and temperatures that vary between day and night, play a significant role in the life cycle of fungi and bacteria. This understanding is critical for pest management and plant care, as recognizing the timing of these symptoms can help in implementing preventative measures or treatments.
