I planted six cucumber plants in a line last week. When I came out the next morning, one had wilted and there was a hole in the soil right at the base of the stem. It was as if someone had stuck a finger straight down into the soil. I sprayed the remaining plants with Sevin, but over the past few days they have all suffered the same fate. Something went right down the line and put a hole at the base of each stem. I dug up the soil but didn't find anything. Any thoughts on what this could be?
Thanks so much!
