Hi I have been gardening off and on for 40 years. I was a city girl, so have had to learn from many sources: friends, magazines, online, work at a florist & garden center. I start getting excited in about February==way too early for the Northwoods as we are still covered with lots of snow. I grow lots of veggies with relatively few problems. This year, however, I have a problem with my cucumber vines. They are producing, but suddenly look like they need water, but don't revive when watered. Help! I don't know what to do.
