You don't have to have a big garden to grow lots of food. Just fill your small garden space with these high-yield crops, and you'll make a big dent in your grocery bill:
Harvest lettuce leaves whenever you need them, and more will grow right back in their place (as long as you don't damage the crown).
Some Leaf Lettuce Varieties: Oak leaf, Red Sails, Mesclun
Plant cherry or grape tomatoes, and you'll get gobs of tomatoes in compact clusters. They'll do well in the ground or in containers, so use any sunny spot that you have available.
Give cucumber plants a place to climb (so they don't take up a lot of space), and you'll end up with more cukes than you can pick, pickle and give away.
Want to grow your cucumbers in containers? Opt for compact or bush varieties. Their vines will only spread a few feet.
Left to its own devices, squash will take over every inch of your garden, but if you grow it vertically, it will do nicely in a small garden, and still overwhelm you at harvest time.
Bell peppers grow up, rather than out, so they're the perfect candidate for a pint-sized garden plot. Smaller pepper varieties also do well. Tuck them into your landscaping (where they'll look ornamental), or grow them in pots on your patio.
Enjoy all you can eat peas in the spring. Then, replant the space with something else for the summer and fall. How's that for making the most of a small space?
Plant a small plot of beets, and you can eat the beet greens early in the season and then the actual beets later in the season. Now that's productive garden space!
It only takes about 45 days for radishes to reach harvest size, so that's another spot in your garden that you can replant.
Train them up a pole or trellis, and your bean plants will give you a huge (and long) harvest in the teeny tiniest of spaces.
Herbs love to share space with other plants. Use them to fill in around your larger edibles, and get more food from every inch of your garden.
