A vertical garden is sure to be a conversation piece in any home or office. It allows you to grow a garden upwards instead of along the ground. There are numerous plants suitable for growing in a vertical garden, and they are easy to construct and maintain.

TIP: Our expert gardening advisor, Susan Patterson adds, "Vertical gardens are a healthy addition to any indoor space as they add oxygen to the air."

Step 1 - Select a Structure

You need a sturdy wall to support your heavy vertical garden. You may even need to reinforce your wall so it can withstand the extra weight.

Most vertical wall kits include forms that you assemble according to the instructions. You can find artificial walls specifically designed for growing vertical gardens. You could also purchase self-supporting panels that you can set independently or attach to a wall.

Step 2 - Fill the Frame with Soil

Fill your framework with good-quality, well-drained potting soil that allows good aeration.

TIP: Susan suggests, "You can also purchase hydroponic vertical garden kits that do not require soil."

Remember to set up a tray to collect excess water that drains to the bottom of the vertical garden; otherwise brown water can spoil your flooring.

Step 3 - Provide Access to Sunlight

Make sure your indoor vertical garden receives sufficient sunlight. You may want to place it near a window in a well-ventilated room. However, on very hot afternoons, put the blinds down for a few hours to prevent the garden from receiving too much sunlight.

Step 4 - Choose Plants for Your Vertical Garden

Choose plants that are easy to grow indoors. They should thrive in the temperature indoors and the sunlight exposure your wall will receive. Lightweight, leaved plants and those that grow close to the root area are better options than large, heavier plants.

Succulents are preferred choices, since these plants are drought resistant. They also offer foliage in different shapes, sizes, and colors. Long vines are another good choice, since they root their way up the living wall as they grow.

Step 5 - Water the Vertical Garden

Vertical garden kits usually include a watering system with a built-in pump, but if you plan to build your own, make sure you place a waterproof liner on the wall you are growing against. A constant run of liquid can cause severe damage and mold. Make sure you address issues such as water retention and drainage when creating your own watering system. The safest way to water a vertical garden is by hand.
