How to Build a Vertical Vegetable Garden for Small Spaces

 
Are you considering getting into vertical gardening? Setting up a vertical garden is a satisfying experience, regardless of whether you're an urban dwelling with limited space or simply want to add some greenery to your house. This simple, step-by-step instruction will assist you in starting your own vertical garden.

What is Vertical Gardening?

Vertical gardening is an alternative gardening technique that expands the possibilities of growing plants in a vertical environment. It is a unique type of urban gardening that works well in limited places, especially for decorating the walls and roofs in different styles. Indoor vertical farming uses efficient growth systems like hydroponics, aquaponics, or other soilless agricultural techniques, and crops are grown in stacked levels.

There are a few key features to keep in consideration while building a vertical garden. Like light exposure, watering, drainage, and plant spacing.

  • Ensure there will be enough light for the plants you choose.
  • Because the soil in vertical gardens can dry out rapidly, they need to be watered frequently.
  • In order to avoid waterlogging, make sure the structure has adequate drainage.
  • Plants should be spaced apart to allow them adequate airflow.

How to Build a Vertical Garden?

Choose a structure, such as a terrace, trellis, tumbling, hanging planters, or a wall-mounted pocket planter system, to create a vertical vegetable garden. Then, plant climbing or vining vegetables, like tomatoes, beans, cucumbers, or herbs, making sure they have the support they need to grow upward by tying them to the structure as necessary. When choosing your location and plant varieties, take into account things like sunlight exposure and water availability.

Vertical Garden Structure Ideas

Terrace

Terracing is the process of creating many steps into a sloping hillside.  If you live next to a hillside this can be a good structure for you.  Each of these steps is higher than the one before it, making them progressive. This technique has been utilized to cultivate vertical landscapes and save water. The Hanging Gardens of Babylon is a well-known urban example of terraced agriculture, which was used by the Romans, Incas, and other ancient societies. In parts of Southeast Asia, rice fields are planted on terraced slopes, creating some exquisite artificial landscapes.

Trellises

Trellising is another great way to grow fruits and vegetables.  Many types of vegetables grow particularly well when trellised.  Cucumbers, beans, and peas are among the plants that naturally tend to vine.  Due to their small root systems and innate propensity to grow upward, these plants may be planted quite close to one another and will maximize the amount of planting space available.  You can also direct little squash, tomatoes, and melons upward by trellising them.

Hanging Planters

Growing plants downward from a hanging planter is called tumbling. If you have more airspace than floor space, you might want to hang one or two planters from your ceiling, eaves, window ledge, or railing. Strawberries, cherry tomatoes, herbs, and bush beans grow very well over the edges of hanging planters, so you have fresh food that "tumbles" down into your vertical growing space. While most hanging baskets are made more for flowers than larger rooting vegetables, you can hang any kind of container that can be supported (keep in mind that wet soil can be heavy).

Cherry tomatoes, strawberries, bush beans, herbs, and even tiny cucumbers can all be grown in hanging planters of some kind. Vegetables that resemble vines and fall over the edge are particularly good at making use of vertical space. Because hanging planters typically have a restricted size, it's important to avoid planting anything too large.

Tower Gardens

A vertical farming technique called the hydroponic tower garden uses nutrient-rich water solutions to grow plants without the need for soil.  Because hydroponic tower gardens have a consistent supply of water and nutrients, they produce exceptionally high crop yields.  Plants are able to grow faster and more efficiently.  Numerous crops, including strawberries, lettuce, Swiss chard, herbs, spinach, kale, broccoli, and blooming petunias, can be grown.  These systems can be purchased online from a variety of suppliers.  Several tower farms have been utilizing the same towers for the past ten years.  In the hydroponic and aeroponics industries, the lifespan of a tower garden is unmatched.

The Best Plants for Vertical Gardens

One excellent example of a plant that may be trained vertically is the cucumber. From the moment a cucumber has its first few leaves, it begins to unroll its tentacles, taking hold of the nearest support. It can attach itself to the stem of a nearby plant, a wire rod, wooden fence, or metal railing. The plant builds its vine by climbing upward and outward with this support. Any material can be used to create a trellis for each plant in a city garden; just make sure it is less than half an inch thick so the plant can grasp it.

Any plant that grows well in a container garden will also do well in a vertical garden. Be mindful that plants with shallow roots, such as annual flowers, vegetables, and herbs, will thrive in a container more than perennials. A lovely trailing effect along fences, trellises, and other upright structures makes vines one of the best plants to cultivate when vertical gardening.

Vegetables require a deep root system to flourish, so they are often not the best choice for vertical gardening, but you may still try other possibilities. Because of their shallow root systems, leafy greens—like spinach or lettuce—are good for container and vertical gardening. Because of their thin root systems, herbs like mint, parsley, and rosemary are also excellent choices for vertical planting.

  • Vegetables than climb:  melons, cucumbers, tomatoes, peas, and beans (runner and pole beans).
  • Herbs for vining:  cilantro, mint, and basil
  • Trailing plants:  creeping jenny, strawberries

Final Thoughts

With new techniques like hydroponics and aeroponics becoming more and more popular, vertical farming appears to have a bright future.  These cutting-edge methods create new opportunities for urban green areas by enabling plants to grow vertically without the need for soil.

Urban green areas have been transformed by vertical gardens, which offer a solution for space constraints.  People may effectively design and care for their own vertical gardens by following detailed instructions.  Recognizing the importance of vertical gardens in urban environments is crucial, as is promoting further research and experimentation in this area.
