Planning your vertical garden is different from planning a traditional garden, but shouldn’t be done with any less care.
Step One: Consider your location. Ideally, vegetable plants should get at least six hours of sustained sunlight a day, so pick a spot that will allow for maximum sun while minimizing filtered light through trees. If a large wall on the side of your house gets the best light, that’s a perfect spot to consider, and even well-lit balconies and porches will work. If it’s available, a south-facing location is the best.
A wonderful aspect of vertical gardening is when choosing a location, you’re not as limited by space as you would be with a traditional garden. In fact, you’ll probably find that you have an abundance of available space when you consider growing up rather than out. Consider that an area as small as an apartment balcony can serve as an excellent vertical gardening spot with just a few containers and trellis supports.
Step Two: As with any vegetable garden, make sure that wherever you choose to place it is close to a convenient source of water or can be reached by a garden hose.
Step Three: Depending on your space, you’ll want to decide whether to plant your vegetables in soil at the base of your growing area or use containers. In either case, use a good gardening soil and augment it with rich compost to provide the nutrients your plants will need.
Step Four: Carefully consider what you’re planning to grow. Naturally vining vegetables come to mind immediately, but don’t rule out other vegetables and herbs that grow closer to the ground. While vining plants will likely require a trellis or some other form of support, those that don’t vine can be planted in nearly anything that you can hang or mount on a vertical surface.
Step Five: Plant seeds just as you would in a traditional gardening, taking care to leave enough space according to the planting instructions. When planting vegetables that will need a support structure, don’t forget to install the supports at the same time you plant, because doing so after the plants have sprouted can damage the root systems.
Step Six: As your vining plants sprout and mature, “train” them to grow upward by manually threading the young vines up through the support system. This is an ongoing process and should be part of your regular garden upkeep.
