Factors Influencing Vertical Crop Viability
When selecting vegetable varieties for vertical gardens, considerations like sunlight, space efficiency, harvest duration and growth rates determine which edibles will thrive. Preferencing crops aligned with vertical cultivation conditions leads to bountiful returns on investment.
Most flowering and fruiting crops require at least six hours of direct sunlight daily. Exceptions like mushrooms and some leafy greens adapt to partial shade. Matching sunlight requirements to exposures prevents struggling crops.
Compact, bushy plant habits maximize vertical space unlike sprawling vines. Steep hanging gardens and wall-mounted pots give preference to dwarfed cultivars, determinate tomatoes and narrowly shaped peppers ideal for tight footprints.
Early yielding crops like radishes and fast-growing leaves keep vertical harvests rolling in. Long-season potatoes or overwintering garlic tie up precious real estate for months better suited to quicker producers.
Vigorous varieties also suit vertical gardens well. Pole bean cultivars bred specifically for Verti culture yield up to 10 feet high, avoiding stooping and squatting! Similarly, cascading tomatoes tumble heavily with fruit. Selecting inherently prolific varieties optimizes vertical bounty.
Leafy Greens and Herbs
Many fast-growing salad greens and aromatic herbs ideally suit vertical cultivation. These edibles reach harvestable size in less than 60 days on compact footprints, withstanding partial shade well. Evergreen perennial herbs persist year-round once established too.
Vigorous kale varieties like Winterbor and Beedy's Camden pack extensive yields into tight spaces. These blue-green superfoods thrive in cool conditions at 8 to 10 inches spacing. Red Russian kale adds vivid color.
Verdant spinach fills staggered containers rapidly as well, bolting slowly. The heavy flat leaf yields of Space and Olympia excel in spring and fall growing. Shade-tolerant chard also produces colorful ribs and leaves into winter.
Delicate, grassy chives lend mild onion zing harvesting multiple times per year. The low-maintenance, cold-hardy clumps spread steadily. Columnar thyme and compact oregano fill gaps with woody herbal scent and flavor. These stalwarts continue producing for years even when root-bound.
Along fences, walls and balconies, leafy greens and herbs make excellent starter vertical crops before adding trailing vines and fruiting plants. Shallow-rooted and acclimated to partial sunlight, these edibles establish reliably on ascending gardens with minimal inputs.
Vining Plants
Climbing vegetables like pole beans, vining peas, cucurbits and crawling melons produce professionally on vertical gardens. Training these long flexible stems skyward saves plot space for other crops. Tall trellises and fencing support heavy yields.
Pole bean varieties bred specifically for Verti culture like 'Apollo' and 'Northeaster' reach up to 10 feet high yielding delicious pods. Similarly, sugary snap peas and snow peas produce abundantly on elongated vines using minimal footprint.
Plant breeders also select cucumber, melon and summer and winter squash cultivars ideal for vertical cultivation. Compact 'Little Leaf' cucumber, clinging melon 'Mountaineer' and bush-habit 'Orange Pippen' squash thrive on fences and trellises.
The sprawling nature of unsupported cucurbits can engulf other plants. But properly trellized and pruned, these fast-growing vines utilize airspace extremely resourcefully. Heavy fruit sets dangle conveniently at hand for easy picking.
With proper irrigation, fertilization and sunlight exposure, vining vegetables morph vertically into bumper crops. These climbing plants can be integrated with containers on poles, walls, balconies even indoors to maximize yields from confined square footage. The expanding foliage provides cooling shade too.
Upright Fruiting Vegetables
Certain compact, self-supporting vegetables thrive planted in elevated containers and multi-tiered gardens. Bright peppers, plump eggplants, bountiful tomatoes, sweet berries and bushy beans adapt well to confined vertical spaces.
Columnar pepper varieties like 'Redskin' and 'Blushing Beauty' yield prolifically in narrow towers maximizing fruit production per square foot. Similarly, miniature Baby Bell eggplants generate abundant clusters on compact plants.
Prolific patio-style tomatoes engineered for hanging pots and wall gardens overflow with sweet clusters. Varieties like 'Tumbling Tom' and 'Tidy Treats' save space while rewarding vertical gardeners with heavy harvests.
Vigorous trailing strawberries cascade from suspended pots awash in sweet red berries. Day-neutral cultivars like 'Seascape' rebloom and fruit steadily beyond a single summer flush. Even compact bush bean cultivars like provider and contour produce vertical legions of tasty pods.
For gardeners maximizing vertical growing in confined areas, installing multi-level shelves of these upright fruiting vegetables makes efficient use of air space. Clustering compatible crops with staggered harvest windows enlivens fences, walls and balconies with a bounty of edible color.
Considerations for Unconventional Crops
Beyond conventional vegetables, creative gardeners also integrate dwarf fruit trees, miniature veggies, mushrooms and microgreens into vertical growing systems with certain considerations in mind. While these unusual edibles require some specialized inputs, they diversify and intensify harvest potential.
Genetic dwarf and columnar tree cultivars produce full-sized fruit on compact profiles ideal for containers and espalier, needing only basic pruning and support. Varieties of apple, peach, cherry, fig and citrus thrive vertically with enough light.
Miniature curiosities like cocktail tomatoes, baby carrots, Peewee potatoes, and dwarf melon cultivars also suit dense multi-tiered configurations in shallower root zones compared to full-sized standard produce. These unusual edibles add diversity.
Similarly, cultivated gourmet mushroom varieties integrate nicely into vertical plans. Inoculating stacked logs or even vertical hanging straw modules generates flavorful crops in the shade.
Finally, ultra-quick microgreens require minimal horizontal space to generate nutrient powerhouses. Certain varieties thrive even indoors under LED lighting adding splashy color and zing.
With a little added expertise cultivating these specialty crops, productivity vertical expands even further. The broad palate of possibilities keeps providing season after season!
Optimizing Conditions for Productivity
To maximize reliable yields on vertical gardens, savvy growers tweak lighting, supports, pollination assistance and irrigation to unlock each plant's potential. Optimizing these environmental factors improves fruit quantity and quality.
While no substitute for natural sunlight, supplemental grow lights extend fruiting periods for vertical greenhouse systems. The latest energy-efficient red/blue LED models from Bloomstart simulate full spectrum conditions.
Installing trellises, nets and cages provides essential structural support managing vigorous growth habit. Strategic pruning also balances plant energy between foliage and flowering. This ensures heavy fruit production rather than purely vegetative expansion.
Hand pollinating flowers with a small brush, or introducing beneficial pollinators via native bee houses and flowering habitat boosts the all-important pollination essential for bumper yields.
Finally, monitoring soil moisture levels prevents over or under-watering. Smart WiFi-enabled irrigation controllers like Rachio automatically adjust vertical garden watering to weather fluctuations and plant needs for flawless care.
By proactively optimizing these key factors, vertical cultivation unlocks maximum productivity from vining and fruiting vegetables otherwise challenging to grow. Lush living walls and tall trellises reward with their exuberant edible bounties!
