Canada Day Cucumber

It's been a long time since I tried to grow cucumbers. This is a Talladega Cucumber. I tried these a few years ago and had no luck. I can't recall exactly what went wrong. Maybe I seeded the containers directly and nothing started, or I transplanted seedlings too early and they died off. This year I started inside a little late and put them out late as well. I planted four plants. One is dead, two aren't growing and one is doing really well. I'm getting lots of male and female flowers which I've been hand-pollinating but so far this is the only one to take.
