Several weeks after planting, the cucumber seeds had yet to reappear as seedlings. I was thinking of replanting seeds (because I was pretty excited about the Mexican Sour Gherkin), but the nursery didn't have any that looked fun, so I bought plants.
The good news? They were on sale, so I got one of all five kinds my nursery sells. I'm feeling a little pessimistic after the bean problems (although it cheered me up to learn that everyone else is having problems too--it isn't just me), and I'm hoping that between the five of them at least two or three will survive.
