Think your garden has no plan? Pull up a shovelful of soil and see: Where will you put all those seeds? There are also seed packets in hand; there are starter plants, too, yet still no idea where to put them in that inviting-looking patch of earth. That’s what most amateur gardens lack: good spatial planning.
How large will things grow before they sprout? Adult plants is something most of us don’t consider when we think about seeds. We can handles a tomato plant that fits into our coffee mugs. Then, whammo, two months later, that baby has grown into a beast of seven feet or more. It entwines its arms around some peppers and cast a shadow on the poor basil.
Plan Your Garden Space
The chart (above) puts things in perspective by ranking vegetables according to their maximum height. Sweet corn is tallest, for instance. Bush tomatoes and peppers is a little shorter, but still manageable. Knowing where your crops fall vertically will save you some head banging.
Planting tall ones on the south side of a bed? They’ll cast a shadow on all below them. Remember that sun moves across the sky; planting tall plants on the north side keeps lower beds happy.
Consider the form of the plants: how much space do they want, rather than just how high they will get? Do they try to climb, which requires vertical support from a trellis or stake? Or do they go sideways and refuse to stay in their lane by spreading out? Think of summer squash as the archetype spread-lead crop. Plant two zucchini seeds, planning on having enough room for eight plants, but one vine want the whole north quadrant.
This is something the visual key clearly points out; there’s a section called “Ground Sprawlers” and another called “Vertical Climbers.” Once you know such things about your plant, instead of battling it you begin to work with it. Give beans a tall fence, give the squash a wide hill, and it all makes sense…for a reason.
There are also rules to size when it comes to container gardening… And if ignored, your pots spill onto patio. A field corn stalk isn’t a dwarf tomato. Not all plants can be treated alike. From a large raised bed for head crops to a micro tray for greens, the infographic shows their niche, and how a twelve- to twenty-four-inch pot works best for patio-dwarfs (anything larger require some serious structural support).
Forget trying to cram a tall indeterminate tomato into a shallow pot. Sure, it may fit at first (but in the long run), the plant will suffer.
Now consider the low-growers. Herbs, radishes, lettuce remain smallish. Frequently under a foot high. In a clever way, they fit gaps between bigger things, making them good for space-efficient gardening. The information shows that while one zucchini may occupy a whole row, a bed of lettuce will be smaller then half that size.
That’s why companion planting works: Here you can stuff radishes in the aisle next to a pepper plant, for instance, and not harm anybody. They have different light requirements and different timing for harvest. Easy math. The more you use every inch of ground for something that likes those conditions, the more you’ll get out of it.
The first thing novice gardeners learn is never to try to plant every single thing all at one time, or assume it will appear exactly the same throughout the year. A garden is a living, changing thing: Things stretch and bend and cast shadows and tussle for attention. Know the range of their mature size, both width and height… And when you do lay things out, you can let them be who they are.
Taller things goes to the rear; the ones that spread go to the sides, and the ones that fill in go in the center. Sounds complicated, right? But it’s really not. You are letting the garden breathe.
Starting with the end in mind means no more guesswork and more progress in your gardening. There will be no more tangles, just tidiness. And you’ll thank your future self for a well-planned garden versus a jumble.
