Indoor Gardening: Growing Plants on Interior Walls and Vertical Spaces

Working as a professional interior designer for many decades, I've been involved in design-and-build residential building projects.

What is Vertical Gardening?

A vertical garden system, also referred to as wall plants, is an indoor or outdoor garden that grows vertically using growth support, like a trellis or a similar support system. It differs from the conventional way of gardening we are all accustomed to, which falls under the category of horizontal gardening.


Many people love gardening but because of today’s way of downsized living, where many people reside in small apartments or condos situated majorly in high-rise buildings, having a garden is almost out of the picture.

For starters, there is nowhere to grow green plants and flowers except in vases, troughs, and pots. Then the fact that these take up a great amount of space on a patio balcony or indoors means the space for plants is limited, which means most of these homes will have to make do with no more than a couple of potted plants in the entire apartment.

Today, you can now grow flowers, herbs, and even vegetables using the vertical garden system, without relying on ground soil for growth.

Benefits of a Vertical Garden in an Interior Space

Vertical gardening enhances the beauty of any space it inhabits, and because they don’t require ground soil to be erected in any residence above the ground floor, your creativity is only limited by your imagination on where to install it, how to place it, and which planting system to use.

You can use any feature that allows you to grow upward without growing outwards, enabling a look that is clean and tidy, devoid of unsightly fronds sticking out from here and there. You can also add the wow-factor to your entrance porch or your patio with wooden hanging wall planters.

Their benefits of vertical gardens are two-fold. They not only look good and aesthetically pleasing, but they also help to filter indoor pollutants and carbon dioxide indoors while improving the quality of air within a space by the emission of oxygen.

The system you use will add to the interior décor of the room, especially if you use natural materials like bamboo poles or natural wood as a trellis, or asymmetrically arranged shelving systems running up a wall to serve as flat surfaces to place plant trays and small terracotta pots.

Additionally, you can use the technique to create interior partitioning or dividing screens to provide privacy in different interior zones. For example, you can use vertical gardening to separate the living area from the dining area or use it to create a division between the dining area and your kitchen.

You can also use vertical gardens systems to create a feature wall in your living room. The wonderful thing about these upward-growing gardens is that they ensure you are using your interior space to its maximum potential.

Herbs and Vegetables

If you grow herbs or vegetables, harvesting them from a vertical garden is easier than if you have to harvest your crops on a horizontal on-the-ground garden. You can harvest standing upright instead of on your knees, great for the elderly and for others with physical challenges.


Best Indoor Plants to Use for Plant Walls

Creepers, vines, and other climbing plants are not the only options available for vertical planting. There are other indoor plants, flowers, vegetables, and herbs you can choose to use to create your indoor garden.

With vertical gardens on the ground floor, you can grow almost anything, including cucumbers, tomatoes, and squash, assuming you are creating one in your small garden. However, for plants that do well indoors, say, on a 7th-floor residence, you may grow any of the following types of plants:

  1. Ferns
  2. Crotons
  3. Philodendrons
  4. Peace lilies
  5. Wedding Vine
  6. Lipstick plant
  7. Succulents
  8. Pothos
  9. Dracaena
  10. Crotons
  11. Lettuce greens
  12. Baby carrots
  13. Tomatoes
  14. Scallions (green onions)
  15. Micro-greens
  16. Ginger

While some of these plants and vegetables require well-drained soil and partial sunlight, if you have inadequate indoor lighting, install a grow light for your vertical garden, especially during the winter months.

The art of growing upwards in an interior space is fast catching on and you can now commonly find do-it-yourself (DIY) kits to buy, which include small cups, pots, and other forms of planter containers or troughs filled with seeds and soil, just ready to be watered for growth, or sets of vertical garden wall planters you can install on your indoor wall.

Once your vertical garden is set up, you must maintain it regularly so that your garden looks healthy, beautiful, and lively.
