Don’t have enough space, go vertical
Vertical growing has come of age over the past few years, with many off-the-shelf contraptions helping space-strapped gardeners get the most from their plot. The really clever ones can turn a bland garden wall into a fresh flush of salads, herbs and fruit – and what home-grown devotee wouldn’t want that? Meanwhile there are all manners of climbing veg plus sprawlers that can be tied into position which will help you to boost productivity from the meanest of footprints.
Climbers and sprawlers
A great place to begin to satisfy lofty ambitions is with the vegetables and fruits that naturally climb or can be made to do so with gentle encouragement. This includes the likes of pole beans, climbing peas, vine tomatoes and the cucurbits: cucumbers, melons, squashes, pumpkins, gourds and sprawling types of zucchini. If you're reading this in a warmer part of the world you can add sweet potatoes to this list. Many climbers produce tendrils that grip the structure they are climbing to literally pull the plant up as it grows. Others, such as the beans, will wind their way around a support to head skywards. The natural sprawlers such as vine tomatoes and courgettes may require tying in to their supports at regular intervals. Either way these will all make the most of the vertical plane. Most tree fruits such as apples and cherries can be trained into space-efficient shapes: vertical cordons, espaliers, fan shapes or any manner of creative but fence-hugging formations. Cane fruits like raspberries and blackberries grow naturally tall – the trick here is to keep them from flailing around onto their neighbors. Grow them hemmed in between rows of parallel wires or tie individual plants to vertical posts.
Vertical growing ideas: There are plenty of ways to make the most of the vertical plane. Here are just a few ideas to get you started.
A-frames: These can be made from wooden trellis, horizontal battens of wood or netting held taut between the two frames. Lean the frames together and secure at the top with wire or hinges. Grow climbers up the two frames and use the space between to grow plants that will appreciate shade during the warmer summer weather: salad leaves and spinach for example. A well-constructed frame can be used year after year – just pull it free from the ground at the end of the season and store in a shed or garage.
Living wall: Invest in one of the many wall or fence-mounted modular planters or panels available. Fabric Woolly Pockets are just one example. There are also many stackable planters that can be built from the ground up. Plant them up with herbs, salads and strawberries and watch a blank space take on a whole new life. Try making your own by hammering in or hanging from hooks all manner of recycled containers: large food tins with holes punched into the bottom for drainage (try painting them for additional interest), rows of window boxes secured one above the other or even pots made from old undergarments as seen at a recent flower show!
Growing vegetables on walls
Hanging about: As well as growing up from below, many climbing or sprawling edibles can be grown from above and left to hang down. Vine tomatoes are best for this and work well in ‘upside-down’ planters. Make a hole into a large bucket that's just big enough to allow you to plant up the tomato. The hole must also allow the stem to thicken as the plant grows. Plant the tomato, feeding compost around the rootball and fill to the top of the bucket. Sow or plant at the top shallow-rooters such as lettuce, radish, basil or stump-rooted carrots. Hang up then feed and water from above while the tomato erupts out from beneath. You can also grow strawberries and other fruiting veg such as peppers and eggplant in this way. The result is literally buckets of produce!
Edible divider: Looking to divide up areas of your garden? An edible divider is far more attractive than a solid conifer hedge or artificial alternative – and you can eat it! Espaliered fruit trees (where the branches run parallel to each other in horizontal rows) make excellent natural dividers. Train the trees onto trellis to provide an all-year-round divider and plant the base up with annual vegetables or flowering herbs such as rosemary to keep pollinating insects busy for longer. Annual climbing veg such as peas and beans make excellent seasonal screens and have the bonus of being very quick growing.
Vertical wall planters
Archway of delights: Visitors will immediately know you’re a passionate grower of all things edible if you plant an edible archway leading up to your front door. Simply plant each archway support with its own climber and watch as over the growing season the archway is consumed by a lush jungle of foliage, pods and fruits. Squashes and beans with colored pods (try alternating purple and yellow-podded varieties such as Blauhilde and Goldfield) look especially impressive given this treatment. The pods and fruits will dangle down above head height to create quite a visual impact. Beans with strongly coloured flowers such as the classic Scarlet Emperor are as floriferous as the best of the traditional ornamental climbers – a feast for both the eyes and stomach.
Ferns and bromeliads in vertical living wall
Ferns: They are one of the garden plants that are preferred for their adaptability and humidity resistance. Ferns are easy to grow and they cover the area quickly. You can grow sword fern, blue star fern, bird’s nest fern, they are easiest. Ferns will generally grow downward, so you’ll need to grow other covering plants with them too.
Bromeliads: Most bromeliads have shallow roots and they need little space to grow this makes them ideal plants for vertical gardens. Their colorful leaves and long lasting flowers can be a good addition to your vertical garden.
Begonias: If you are hanging your living wall in a place that receives some sun then growing begonias is a good idea.
Hostas: This beautiful plant with variegated foliage is used as a groundcover in gardens. For a shady site, this evergreen plant is suitable for a vertical garden.
Lipstick Plant: Growing lipstick plant is easy. It doesn’t require deep soil to grow so it can thrive in a vertical wall. You can also grow it indoors.
Succulents: Succulents are the most used plants for vertical gardens due to their incredible adaptability and resistance to fluctuation in temperatures and climatic variations. Plants like the string of pearls, echeveria, crassula and sedum can be considered.
Air Plants (Epiphyte): Such plants do not need soil to thrive, they grow naturally on other plants, which make them perfect for growing in vertical wall gardens. Tillandsias, aechmea, vriesea are a few examples.
Vines: Low maintenance vines such as pothos, ivies, philodendrons, rosary vine and wandering jew can be grown vertical planters easily. They are low maintenance and even thrive in indirect sunlight. – TTN
