A green wall features a range of different plant species designed to thrive in the environment they’re placed in, and with hopefully minimal care.

An indoor green wall is one of these vertical gardens placed inside the home. There’s no limit to what room of the house you might grow one, however, many people find they suit best in the kitchen or living areas.

For an indoor vertical garden green wall, there are some key differences to the outside models.

You’ll have to consider temperatures, sunlight, irrigation, and general care before deterring which ones are best, and if you’d rather not purchase one of the ready-made kits or walls, there are ways you can develop one for yourself.

How to Make a Green Wall Indoors

There are lots of ready-made green wall structures available to purchase, but it is possible to make a simple green wall yourself at home.

If you’d rather take the DIY approach, you can use a few simple tools and the right choice in plants to construct a vertical garden without the hefty price tag.

The Installation Process

To make a DIY green wall inside your house is easy, and you have the option to make it as large or small as you desire.

Follow these steps to get the basic foundation of your green wall started, before moving onto the plant selection.

  1. Find an ideal space in the home if the area you’ve chosen. You’ll need a solid wall or fence, or even a portable wall that can be moved around if needed.
  2. Mark out the positions of the planets of the wall with a pencil and then screw in treated battens around 15 inches apart horizontally, and another 15 inches vertically. This will enable you to place one plant in each of these with adequate room to grow. Use a spirit level to check everything is even as you go along.
  3. Attach one plastic planter to each batten you’ve screwed in and ensured it’s fastened in place. With all of the planters lined up, check to make sure everything is even.

Choosing the Best Plants for a Green Wall

For an indoor vertical garden, some plants will perform better than others. These are shade-tolerant plants that add a good texture to a wall and are easy enough to care for.

  1. Ficus leaf

A ficus is shiny and healthy-looking, with leaves varying between reds and greens. Having a ficus on your vertical garden can be good for areas that still get sunlight, as they’re able to withstand some UV, but do best as an indoor plant that’s kept in the shade.

  • Laurel leaf

A laurel is key to making your garden have some volume, as their leaves are small but plentiful. This leaf is adaptable to both indoor and outdoor settings, so if you ever decide to move your wall outdoors, it will perform just as well.

  • Ferns

There are loads of good indoor ferns that thrive in the conditions inside a home. By utilizing more than one type of fern, you’ll get a very distinct look, but all with the low maintenance that these plants are known for.

Planting the Plants

The final stage is planting your chosen plants into the wall’s planters. This step is about lining everything up and making sure the green wall is neat.

The key to a thriving wall is one where plants have enough space to grow, but also one that is aesthetically pleasing.

  1. With the plants chosen and enough to fill all of the pots that are placed on the wall, you can now get to work planting them. You can choose to keep them in their plastic pots or move them straight into the planters.
  2. Perform a watering with a can or indoor hose to make sure the soil is moist, and if you decide to later, you can consider adding an irrigation system to make the watering automatic.

Keeping Your Plants Hydrated

The irrigation system of a green wall is perhaps the most important part, as, without it, your plants will go thirsty and start to suffer.

In this type of indoor garden, there are three categories that your irrigation can fall into. Which is best will depend on how much effort and money you want to spend, the size of your garden, and any other specifics you want to achieve.

Recirculating Irrigation System

A recirculating irrigation system is powered by an irrigation tank that holds the water. This can be turned on and off remotely or directly underneath the garden, and it requires the tank to be filled regularly with fresh water. 

The pump connected to the tank delivers water to the back of the green wall so that it reaches the soil. Gravity does its work by dragging the water downwards, so whatever isn’t’ used can then be collected. This excess water is fed back into the irrigation tank and used over and over again, so it’s a sustainable and environmentally friendly way to keep them watered.

Direct Irrigation System

Direct irrigation implies a system that delivers fresh water direct from a source like a water pipe or water main and into the garden. This water is channeled straight to the soil and plants without the need for a pump, as it has enough pressure coming from the pipes.

The water is also pulled down, thanks to gravity, but rather than being recirculated, it is fed out to a sewer drain. This isn’t the most eco-friendly option, but it can be the only choice for some vertical gardens, depending on their setup.

Manual Watering

If you don’t want to go to the expense and time of setting up an irrigation system, you might prefer to water the plants yourself. This can be done simply with a watering can or a small indoor hose, and allows you to monitor how much is being fed to the plants.

You can still set up an excess water collector underneath the plants which can be used to water them the next time, so nothing is wasted. This is a good option for smaller green wall setups or for people who would rather be in control of the watering schedule of their plants.

Ongoing Maintenance and Care

As with any garden or plant in your care, there’s more to do than just the initial step of planting it.

More than a regular houseplant, these green walls need ongoing maintenance and care in addition to their feeding and watering schedule, so it’s a constant job to keep one thriving.

The maintenance phase should be considered in the initial stages when planning your wall so that you choose something that suits your commitment. There are options for low maintenance vertical gardens if this is all you’re able to commit to, and some that require hands-on and serious care to keep thriving and in the best condition.

When planting your new vertical garden and choosing which plants you’ll use, keep in mind that these ongoing maintenance tasks will need to come into the equation as well:

  • Checking for weeds and controlling outbreaks with pruning and other methods of removal.
  • Inspections of the support structure to look for signs of weakness and areas that need repair.
  • Making sure plants and their roots are only growing in the vertical garden’s structures and not starting to protrude or make their way into nearby walls and other fixtures.
  • The ongoing removal of plant waste like leaves, twigs, and garden clippings.
  • Keeping the levels and appearance of the wall consistent, by either adding new plants or removing parts that have overgrown.
  • Understanding common plant diseases and knowing what to look out for in the plants on your green wall.
