Reduce the likelihood of fungal diseases by watering the soil, not the leaves of the plants.
Reduce the likelihood of fungal diseases by watering the soil, not the leaves of the plants. If you use a sprinkler, do it early in the day so the leaves will dry by nightfall. If a plant falls prey to a disease, promptly remove it and throw it in the trash; don't add sick plants to your compost pile. Additional disease preventatives include growing vegetable varieties listed as disease-resistant and changing the location of your plants each year (crop rotation) to reduce disease-causing microbes from building up their populations.
