My cucumbers are sick. As far as I can tell (although I’m not 100% certain), they’re suffering from something called Alternaria Leaf Blight. But no matter what the particular fungus is, the leaves have expanding brown spots and are beginning to yellow and die, starting from the roots and working their way upward. New fruit is being aborted. It’s sad—very, very sad.
I don’t often have to contend with diseases in my garden. Good horticultural practices lead to healthy plants, and healthy plants resist disease. However, given our erratic weather and cold nights, I grow my cukes in my little greenhouse. Because options are so limited, I plant them in the same spot year after year. Even though I renew the nutrients in the soil, fungal spores accumulate, and now I’m dealing with the unhappy result.
