Q.continual fungus damage to all my nightshade vegetables
For 3 seasons any peppers, tomatoes, and other vegetables are destroyed by molds and blights even when planted in entirely different sections of the garden. I am at the point of giving up on growing peppers, because Why Bother?? No pics, but the symptoms are always beginning with a soft dark spot, sometimes encircled with a ring, sometimes not. However, it eventually destroys the entire fruit. I do NOT want to saturate my garden withagricultural chemicals. I fertilize with my own good compost and mulch heavily each year either with good straw or preferably pine straw going about 3-4 inches. Thanks,
It is very important to practice crop rotation to keep plants healthy; especially plants in the Nightshade family.
