Not Enough Garden Space? Try These Small Veg Garden Ideas
By Steven Biggs
Fit More Vegetable Plants in the Same Small Space
Ideas to help you harvest more from the same small space.
Want to harvest more fresh vegetables from your small-space garden? Sometimes it helps to forget what you’ve seen. And do things differently from what's done in a big garden or commercial farm.
Commercial growers often focus on uniformity, and on perfect, unblemished produce. They also need space for equipment or employees to work around the plants.
But in a small home edible garden, where there’s not a lot of growing space—and where we’re just growing our own food—our needs are different. We want a variety of crops. We want an ongoing harvest. And we want it to be simple enough to fit into our everyday routine.
If you're struggling to fit everything you want to grow in your vegetable garden, keep reading for ideas to make the most of your growing space.
Key Takeaways: Make the Most of a Small Vegetable Garden
Recommended plant or seed spacing sometimes uses more space than required in a small vegetable garden.
Vertical gardening helps to fit more plants in a small garden bed.
Companion planting is a simple way to boost the output of a small vegetable garden.
Farmers sometimes leave fields fallow, but there's no need for this in a home vegetable garden.
Many crops have more than one edible part, making crop choice a simple way to grow more of your own food in a small space.
Reconsider Plant Spacing in a Small Vegetable Garden
Do you grow vegetables with the spacing suggested on seed packets or plant labels?
I don't. I always sow carrots, lettuce, and beet seeds more densely than recommended. Then I thin them out as the plants start to grow.
And the thinning is not a waste. Because I eat the small plants that I've thinned out. Baby carrots, lettuce, and beets are a treat.
Recommended plant spacing usually gives plants a suitable amount a space to develop to their final size. But there's no reason you can't use some of the space to grow baby plants while the crop is small.
There are lots of other ways to save on spacing. I often plant a few onion sets on the sloped edges of my raised soil beds. They might not get quite the amount of space recommended...but I'm using space that might otherwise not be used.
My daughter is an avid tomato grower. Some years she's trying to fit 100 varieties into our yard. She does that by planting them close together, and then growing them up twine (see Vertical Gardening, below.)
Take Up a Smaller Footprint with Vertical Gardening
Use Vertical Space in Your Vegetable Garden
Growing vining peas up a trellis in a small garden.
When space is at a premium, don't let vining plants sprawl all over the garden bed. Grow them upwards, instead.
I’ve seen watermelons growing on A-frames, each melon supported by a sling! And there are other vining plants such as cantaloupe, indeterminate tomatoes, and cucumbers that you can grow vertically to maximize yield in a small space.
With the vining plants growing up your A-frame, you can now grow shade-tolerant vegetables such as leafy greens under the A-frame.
Here's another idea: My neighbour Joe has a 10-foot-high wall of pole beans around his vegetable garden…an edible wall! Bush beans are great, but if your growing space is at a premium, pole beans take up less of a footprint.
Choose Varieties Suited to a Small Space

When planning your vegetable garden, variety choice can help you grow vertically to maximize your available space.
Some plants, such as peas, beans, tomatoes, and squash, are available in both vining and bush forms. Fit more into a small space by choosing the vining varieties that you can grow vertically.
Bush beans are a great choice if you want a larger harvest all at once for a big feed or preserving...but the trade-off is that they use more space.
Small Space? Grow Vegetables on Fences and Walls
Make the most of your outdoor space by growing on walls. All you need is a trellis or twine.
An empty fence is a wasted opportunity. My neighbour and I share the squash that I grow along our fence. Great way to hide a chain-link fence!
(And don’t forget that the top of a fence can be dressed up with a window box. A fence-top container garden!)
Try Companion Planting
Companion planting just means growing different plants together for some sort of benefit.
Companion plants might attract pollinators, lure away pests, deter pests, or attract beneficial insects. Those beneficial insects can help with pollination, or they might parasitize or eat insect pests. There are lots of opportunities for companion planting in a vegetable garden.
Below are a couple of ways to use companions to fit more vegetables into your small garden.
Plant 2 Different Crops in the Same Spot—at the Same Time
Growing radish and carrots together. The radishes are ready to harvest while the carrots are still quite small.
Waste less space by planting both fast- and slow-germinating seeds in the same space, at the same time.
My favourite example of this combination is pairing carrots and radishes. They are both root vegetables. And they are well-suited to being grown together in the same space because one grows quite quickly, one slowly.
Carrot seed is slow to germinate; radish seed is fast. And radish roots are ready to pluck from your garden way before your carrot roots are even getting chubby. That means you’ll be harvesting full-grown radishes just as your carrot seedlings need more space. As you pull out the radishes, you give the carrots more space to grow.
Wondering how one plant benefits the other in this scenario? Pulling out the radishes, which have taproots, also loosens the soil for your carrot seedlings!
Pair up Sun-Lovers and Shade-Lovers
When deciding which crops to plant together, think about sunlight.
If you have staked tomato plants, there can be a lot of unused, shady ground around them. (If it’s not yet shady, it will be, once the tomato plants get bigger.) Sprinkle seed for leafy vegetables at the base of your tomato plants. Lettuce lasts much longer when growing in some shade in the heat of summer.
Or, make an a-frame for growing climbing plants, and plant leafy greens in the shade below.
Use Your Garden Space as Long as Possible
Start as early as possible in the spring with cold-hardy crops. If your garden includes containers and raised bed, remember that the soil in containers and raised beds heats up more quickly than the ground, and that heat can speed along early spring sowings.
As your crops mature, plant new crops in the same space. Farms sometimes have “fallow” fields, unplanted fields, to control weeds or to conserve moisture. That’s fine for farms—but not for a small vegetable garden. Use your space continuously. You just need to recharge your soil nutrients, and you can do that by amending your garden soil with compost.
Don’t forget to grow cold-hardy crops in the fall to overwinter in cold frames and harvest all winter long. You can also plant cool-season crops in late summer and fall to harvest in early winter and further extend your harvest window.
Grow Vegetables That Produce a Lot in a Small Space
Radish seed pods are edible! A crunchy, peppery garnish.
Grow Plants with Multiple Edible Parts in a Small Garden
Growing plants with more than one edible part is a great way to get more from your growing space. Many plants have more than one edible part.
Growing beets? Eat the leaves, too, which are like chard. Garlic makes “scapes” that are edible and sought after by gourmet chefs! Radishes? Try the crunchy, peppery seed pods. One year, my daughter made pesto from young radish leaves…who knew?
In a Small Space, Plant Vegetables That Mature Quickly
Brussels sprouts? Leave them for farmers because they take up growing space ALL season and then you only harvest them once there's a fall frost.
As you think about vegetables to grow, consider kale, which you can be harvesting spring through fall, and even into the winter. Or cauliflower, which, after you harvest it, you can follow with another crop of something else.
Extend a Small Garden with Containers
Using containers to make additional growing space beside this small garden.
Add Containers to Small-Space Gardens
Container gardening is a great way to extend a small vegetable garden, even if you don't have more in-ground growing-space.
Extend your small garden onto a patio, a deck, driveway or rooftop. Or even add window boxes.
For best results growing in containers, use a good potting mix. Here's more on potting soil.
And Finally...Forget Perfection in Your Small Garden
You probably don’t have the ideal conditions for some crops. Maybe your garden soil isn’t quite what you want…maybe you don’t have enough sun.
If you were a commercial market gardener, this could be a big deal.
But if you’re a home gardener, figure out how to make the best of what you have. For example, I grow tomatoes in a container garden on my driveway—in less than 6 hours of sunlight. I get A LOT of tomatoes from space that would otherwise go unused. Sure, it’s fewer tomatoes than if I had full sun on my driveway. But it’s more than I’d get if I didn’t grow there.
Gardening is a great cure for perfectionism. There’s real satisfaction in harvesting fresh produce from your own garden.
