We’re wrapping up our series on Making Gardening Easier with a refinement that can be applied to any of the types of gardening that we’ve discussed — whether traditional farm-style rows or raised bed, container, or straw bale gardening. Vertical gardening can add a whole new dimension to the way you grow vegetables.
The point of vertical gardening is that you grow your garden up, not out. There are a number of advantages to this approach:
- Less space — By growing vertically instead of out horizontally, you can fit more plants into less space. Vertical gardening is a natural add-on to your patio or balcony container gardening, but it also works well with any other form of gardening.
- Less soil and water — People have been using some vertical gardening techniques in traditional row-type gardens for centuries, but when you apply it to container, raised bed, or straw bales gardens, you’ll need only enough soil to grow the plants in and you water a smaller area, too.
- Less weeds, pests, and diseases — Growing your plants up a trellis, mesh fence, or other structure will keep them from dragging on the ground and give the leaves and roots more exposure to air circulation and the sun. This will reduce or eliminate the environment that some garden pests and diseases thrive in, making your plants healthier and more productive.
- Less work (hence making gardening easier) — You don’t have to till and cultivate a large plot of ground to have a successful vertical garden. Or you could, if you wanted to. You make the call. But you can grow a productive garden in very little space, making vertical gardening ideal for city dwellers or for anyone who wants to make the best use of a sunny spot.
There are some plants that are more prone to growing vertically than others. Pole beans come to mind. (Remember Jack and the Beanstalk?) So do peas, cucumbers, grapes, squash, melons, tomatoes, and grapes. Anything that grows on a vine is a natural choice for vertical gardening. These guys will all gravitate toward a stake, cage, trellis, mesh, or chain-link fence. Whatever they can sink their tendrils into. All of these are tasty candidates for your first vertical garden. (Squash and melons in a vertical garden? Yes, it can work!)
Vertical Gardening with a Traditional Row-Type Garden
One of the best ways to integrate vertical gardening with a traditional farm-style row garden is by means of erecting a trellis over one or more rows of the garden. The trellis can be a metal wire fence mesh stretched over a frame, or it could be a lightweight nylon mesh stretched between poles. The trellis could be straight vertical, or it could be an A-frame that allows your plants to grow up at an angle. Any way that you want to do it, just make sure that you’re trellis mesh and frame are strong enough to hold all the food that will be growing on it. Also take into consideration that you’ll want good access to your plants from both sides of the mesh. If you build an A-frame with tight chicken wire for your mesh, you might be constructing a barrier that keeps you from harvesting all of your crop.
Of course, everything that you can do with a traditional garden can also be done with a raised bed garden.
Vertical Gardening with a Straw Bale Garden
In a previous blog with talked about Joel Karsten’s straw bale gardening method. Joel says that one of the keys to a successful straw bale garden is to pair it with vertical gardening. He recommends that you rig up an espalier (yeah, we’re getting fancy with French words now) trellis over your bales. Joel uses sturdy metal stakes at either end of his row of bales and strings wire between the stakes at ten-inch intervals up the length of the stakes. He adds a 2×4 header that he attaches as the top frame on the stakes to keep them from sagging and collapsing inward as weight builds up on the trellis strings.
But what about those edibles that we might call “vertically challenged”? Is there any way to use them in a vertical garden? Lettuce, carrots, broccoli, onions, herbs, and strawberries aren’t exactly good candidates for creeping up a trellis. This is where container gardening fits into your vertical gardening plan.
Low-growing plants can be grown “vertically” by using creative ways to arrange their containers vertically. For instance, you could use the blank space on a garage wall or boundary fence to attach rows of rain gutters. These make great containers for lettuce, herbs, and strawberries. Some people have taken a closet-door shoe caddy with lots of pockets for pairs of shoes, filled each pocket with soil, hung it on a sunny wall, and grown food in it. (While this can be done successfully, some garden supply companies have adopted this approach and made fabric multi-pocketed containers that are designed with the specific goal of creating the best environment for growing plants, not storing shoes.) And don’t limit your concept of vertical to just mean growing upwards. You can grow pole beans or peas in a hanging basket and have the vines spill over the edge of the basket and grow downward.
Vertical gardening is a way for you to let your fertile imagination (pun intended) run wild. With just a little bit of nutrient-rich soil and a sunny spot anywhere in your yard, porch, patio, or driveway, the sky’s the limit.
We found an excellent book on vertical gardening by Chris McLaughlin. She covers growing vegetables, fruits, and herbs vertically with specifics about which varieties work best. There is a very helpful section on vertical gardening structures. A great book for those who are just getting started.
