Arugula, also known as rocket, is the yummy, peppery brassica that's perfect for spicing up salads, sandwiches, even pizza. To get the best flavor from your leaves, though, you need to know exactly when to harvest arugula.
If you are harvesting lettuce, you may pick arugula at the same time, and you can choose to do so from both young and more mature plants. Ruth Hayes, gardening expert for Homes & Gardens comments: ‘It is a versatile plant and can be harvested as baby leaves or as fully mature additions to your salads and stir fries as a spinach substitute. The flowers are also edible if you let your plants run to seed.’
