My cucumber vines were looking great—and then the vines started to wilt, though the soil wasn’t dry. Why?
Bacterial wilt, which causes leaves and then entire vines to go limp, is spread bycucumber beetles (who also chew holes in leaves).
The key is prevention—there is no remedy for infected vines. Use floating row covers to keep beetles off young plants (opening them at pollination time), and handpick beetles aggressively if they emerge. Rotate where cucurbits are grown.
Sowing more cucumber seeds every couple of weeks until three months before first frost for multiple generations of plants may help, as some are bound not to coincide with beetles.
