You don’t need a big garden to produce a large harvest. Growing high-yield vegetables is an easy way to maximize your growing space. High-yield crops are those that produce the most food per square foot of garden. There are plenty of great books on growing more food with less space, including the recently released book, High-Yield Vegetable Gardening by Colin McCrate and Brad Halm.
I practice high-yield gardening in my own raised bed garden and here are a few of my favourite crops that give the best bang for your buck:
6 High-yield vegetables:
1) Pole Beans. Pole beans are vigorous climbers, and can grow 10 feet or more to ramble over fences, teepees, trellises, or netting. As well, they consistently out-yield bush beans when grown in the same amount of space. My favourite varieties include ‘French Gold’, ‘Emerite’, ‘Rattlesnake’, and ‘Purple Podded Pole’.
2) Peas. Just-picked peas are a true garden treat and most of ours are devoured while standing in the pea patch. Like pole beans, peas are grown vertically, taking up a minimum of garden space, but producing a heavy crop for several weeks. I love experimenting with different pea varieties, but I always come back to ‘Super Sugar Snap’. This variety has it all – plump edible pods and sweet juicy peas that are produced on 5 foot tall vines.
3) Zucchini. Zucchini is often considered a garden thug, growing vigorously and taking up more than its fair share of space. However, zucchini plants are also food factories, pumping out a ridiculously generous harvest. I’m obsessed with ‘pattypan’ types like ‘Sunburst’ and ‘Bennings Green Tint’, the heirloom ‘Costata Romanesco’, and Lebanese types like ‘Clairmore’.
4) Salad Greens. Salad greens like lettuce, spinach, and arugula are high-yield superstars! They are super speedy to grow and can be planted in small spaces and containers. Use greens to edge a garden bed, fill the space beneath a pole bean teepee or A-frame trellis, or as a living mulch between slower growing crops. For lettuce, I rely on looseleaf varieties like ‘Red Sails’, ‘Red Salad Bowl’, and ‘Drunken Woman’. ‘Corvair’ and ‘Tyee’ are among my favourite spinach cultivars and ‘Astro’ is a reliable arugula with dark green, deeply lobed leaves.
5) Tomatoes. Tomatoes are the #1 garden crop in North America, but they are also a high-yield vegetable that can produce a heavy crop over an extended period of time. We grow a wide range of heirloom and hybrid varieties, with cherry ones like ‘Sungold’ and ‘Jasper’ being extremely prolific, and large fruited varieties like ‘Mountain Merit’ and ‘Chef’s Choice Orange’ taking us from mid-summer to the autumn frost.
6) Cucumbers. Cucumbers are produced on either bush or vining plants. Bush varieties have tidy growth and can be popped into containers or small garden beds, but produce fewer fruits per plant than vining types. Vining cucumbers, on the other hand, will ramble over open ground or quickly scale a fence, A-frame trellis, or netting. We love the heirlooms ‘Lemon’ and ‘Boothby’s Blonde’, and hybrids like ‘Diva’ or ‘Pick a Bushel’.
