While most cucumbers are picked when they are small, the cabbage family plants can continue to grow for months if left unharvested. With that in mind, here are the steps you should take when picking your cucumbers:
• Pick them before they get too big and before the stem goes dry.
• Pick them once their color turns from dark green to light green. They should be firm but not hard.
• Pick them while they're still young and tender enough to eat without cooking or canning.
