You can start cucumbers, squash & zucchini in cups as transplants 2-4 weeks before they would go into your garden. You want 50 degree nights and days that get into the 70+ degree range for planting them outdoors in the ground. But you can start them in cups, during cooler weather. They make great transplants and you can get them started while you get your beds ready and wait for the right temperatures.
