The foliage on our cucumber plants is starting to wither and turn yellow. They get plenty of water and I feed them regularly. What could be wrong?
“The plants may be getting too much water. They can tolerate fairly dry soil,” says Tim Norris, owner Spring Bluff Nursery, Sugar Grove. There are other possible causes for yellowing foliage as well. The cucumber beetle may have fed on the plants when they were small and transmitted bacterial wilt, which later plugs the vascular tissue. To prevent the beetle from feeding on young plants, use row covers until the plants get larger. A stressed plant is also open to attack by bacterial wilt.
