Vertical gardens, which are walls covered with magnificent blooms or patterns of greenery, are commonly found in public locations. 

However, did you realize that edible plants may also be grown in a vertical garden? In reality, with a little forethought, you can grow a variety of fruits, herbs, and cruciferous vegetables on a sunny wall. Sure, several food plants will grow in this sort of isolated ecosystem.

Because vertical gardens are so diverse, we'll concentrate on those that work best for residential vertical garden structures where edible plants thrive the most, preferably vegetable plants. 

If you're intrigued by edible flowering plants, we'll discuss some more of these plants which droop, climb, and grow in a vertical manner. With this, sure, you will be able to find and pick one that complements your vertical gardening systems.

What Exactly Is A Vertical Garden?

A vertical garden grows vertically rather than laterally in a row. Most vertical gardens are cultivated in a container, whereas most conventional gardens are grown in normal garden beds.

Vertical gardens vary from simple household pot gardens made of recycled plastic materials to vertical garden systems that employ hydroponics and artificial intelligence (AI) to cultivate and collect food for commercial sale.

What Are The Best Edible Plants For Vertical Gardens?

Vertical gardens come in all shapes and sizes, though in theory, any plant that can be grown in shallow pots can be grown in a vertical garden.

Here's a quick list of edible plants that thrive in vertical garden structures, grouped by potting depth:

1. Plants with shallow roots

Lettuce, green onions, radishes, spinach, and chives are examples of cruciferous vegetables with shallow roots that grow upwards.

These plants work best in individual pots with nothing more than a depth of at least 6 to 9 inches.

a. Radishes

Radishes edible plant

For the maximum depth of flavor and texture, use shorter types for shallow pots and keep them regularly watered. In most climes, you may either plant them as a direct sow or as a spring and fall crop.

b. Leaf lettuce

Leaf Lettuce verticle garden

You can prepare lettuce seeds indoors or plant them as a direct sow. However, ensure consistent hydration and nutrition with high-quality organic compost. Thankfully, the majority of climates allow for both spring and fall planting.

c. Spinach

Spinach for verticle garden

Seed directly. Cut the leaves separately when they're young to acquire well over one harvesting yield from the plant; the leaves will regenerate with regular exposure to full sun rays and produce repeated harvests. 

If you like bigger plants, and lesser frail leaves, clip the plant off from the soil and harvest it all at once. Consume either boiled or fresh. In some areas, it may be planted as a spring and fall crop. 

d. Green onions

Green Onions

Green onions are often known as bunching onions. You can begin with seedlings, sets, or transplanting. This plant requires good drainage holes and high-quality organic compost to produce edible root vegetables.

e. Cabbage Chives

Cabbage Chives

This perennial edible garden plant demands full sun rays, drained rich soil, and plenty of organic matter in the soil. it can be cultivated in window boxes as a houseplant; however, growth slows or stops in the winter.

2. Plants with moderate root systems

Edible garden plants with moderate roots include peppers, peas, eggplant, and carrots amongst others.

These plants thrive in pots containing fertile soil with a depth of at least 12 to 18 inches.

a. Peppers (sweet or spicy)

Peppers edible plant

Start growing peppers indoors for approximately two months before placing them outside. Excess nitrogen delays fruiting, so it is best to keep them in partial shade out of full sun rays. Select climate-adapted cultivars, particularly when planting in cooler regions.

b. Peas 

Peas edible plant

Peas may be sown as direct seed outdoors. They may grow in a variety of soil mixes, but they must have adequate drainage holes. It is preferable to select a wild or vining plant species.

c. Eggplants 

Eggplants edible

Start planting eggplant indoors for eight weeks before transplanting outside. When transplanting seedlings into the garden, use plant supports. Once a week, thoroughly water the plants. Please do not soak the leaves.

Swiss chard may be grown from seed or transplanted. Pluck tender leaves for harvests.

d. Herb

Herb vertical garden

Herb gardens are popular in small spaces, including window boxes. Standard-sized specie demands more space and light for larger yields. 

One plant per 8-inch-diameter container is a good starting point. Alternately, utilize a variety of them in an arrangement like a hanging basket, but don't anticipate them to produce as much.

3. Plants with deep roots

Plants such as cucumbers, tomatoes, and beans may be grown atop a wall or in a normal garden bed that can be hung on a fence or wall, with the fruit secured as required as the vines descend toward the ground.

a. Pole beans

Pole Beans

Pole beans are precisely what their name suggests. They produce pod-producing vines which grow along a pole or across a trellis. Pole beans are tastier than bush beans and will keep producing beans pod throughout their growing season.

b. Squash 

Squash edible plant

Squash grows well on a trellis. Guide and support your vines as they grow and develop fruits and be certain to include a sling for the fruit as it appears, notably for winter squash, which is often heavy.

c. Cherry tomatoes

Cherry Tomatoes

Tomatoes thrive in full sun light and well-drained soil. Bush (determinate) or vining tomatoes can be grown successfully in a vertical garden.

If you want to plant vining tomatoes, you'll need to attach the vines to a trellis. This will help the vines yield fruit while also keeping them in order as they develop.

Additionally, tomatoes are grown hydroponically or in soilless conditions to yield bountiful harvests all year long.

Lastly, beautiful ornamentals/ decorative plants like Bromeliads, Morning glories Orchids, and Pothos can also be planted in vertical gardens

Which Plant Cultivars Are most Suitable For Vertical Gardens?

When growing in containers, conduct your study to locate cultivars that thrive well in containers. If you want a plant that is smaller in size, you can also seek bush variants of several crops, which are often non-vining.

However, if you would like to set up a trellis or place the pot beside an Arbor, trellis, or perhaps a fence, vining cherry tomatoes, and melons, for instance, are ideal for growing vertically. If your notion of vertical gardening is to line your back stairs with pots, bush plant variety may be a closer option.

Some Rule of Thumb in Vertical Garden Planting

Here are some pointers to make your vertical garden survive and flourish:

1.     Every year, practice continuous crop rotation.

2.     Choose plant varieties that thrive in your climatic region.

3.     Prepare a watering strategy for those week-long midsummer travels.

Simple Steps To Grow A Vertical Garden

Steps To Grow A Vertical Garden

1.      Monitor the sun's rays: Estimate the number of hours of direct sunlight or shade your garden receives daily.

2.      Select your plants carefully: Choose plants based on the amount of sunshine you receive.

3.      Set your vertical garden structure: You don’t need an elaborate structure to start a vertical garden. Poles, a trellis, or other sorts of supporting structures will be sufficient enough to guide and secure the vining plants.

4.      Pick a container: Select containers according to your plants' mature size. Aside from that, be innovative and recycle what you currently have to reduce unnecessary expenditures.

5.      Gather a couple of packs of potting soil: It is vital to choose soil mix that has high drainage and water-retaining ability. Sand, for instance, is not a suitable option for most plants, it drains too quickly and does not retain sufficient water.
