If there is one crop you can seriously save money on by growing your own it's lettuce. Even if you don't have much space you can grow lettuce in containers easily on a balcony, windowsill or small patio.
Growing lettuce, whatever the variety (there are a lot), is just as easy as knocking up a simple green salad. From hearty butterheads to the more compact oak leaf variety, you don't need a large garden to enjoy delicious lettuce. In fact, growing lettuce in pots has the added benefit of protecting your green leaves from slugs and other pesky garden pests.
