You should spend money on a high-quality mix or make your own.

There are differences in the industry when it comes to using the phrases potting soil vs. potting mix. A patio or terrace garden needs a soil-less potting mix. Dirt or soil from the ground is not sterile and can cause problems like diseased plants. Keep reading this post as we explain in detail how to get the right mix for your garden.

How Do You Start A Terrace Garden?

It's exciting to start planning your very own green space on your terrace. You already know that you need a healthy soil mix. The other important element you need is sunshine. To help you get your garden going, we've compiled a few best practices below.

Plan Your Space

Before you decide what to grow, you need to determine how much space there is to work with. If you have adequate space, you can plan for a container garden or use pots to arrange your plants. Keep in mind that an elevated area might have weight limits. Containers full of soil tend to be heavy to lift. Should space be at a minimum, or if you want to optimize your area, you can always think vertically.

Vertical gardens can be established on a wall or suspended from a ceiling with chains. There are also options for your garden to be freestanding on a ladder or rack.

Look For Natural Light

Before you commit to a plan, spend a day watching the way the sun shines on your terrace. Most plants require a minimum of six hours of sunlight a day to thrive. On the other hand, direct all day sun might mean you need to plan for a barrier of shade. Or choose tropical plants that can take the heat.

If your terrace lacks sunshine, you can always invest in grow lights. You'll need an outlet to plug the lights into, but they can produce the type of light your plants need to thrive.

Access To Water

A terrace built at ground level should be simple enough to water. Make sure you have access to a hose or the ability to bring water to your containers.

Utilizing self-watering pots might be more carefree if your terrace is at an elevation. Another option is to build a drip irrigation system that will provide water to your plants. If you are using pots, make sure they are set on saucers or trays to catch excess water.

How Do You Mix Soil For Container Gardening?

A nutrient-rich soil mix will contain a formula of organic ingredients of peat moss, vermiculite, and compost. You can use your mature compost or purchase topsoil to add to the mixture.

You can start from scratch and mix equal parts of compost, peat moss, and vermiculite in a large container. If possible, you can mix it on a tarp in a large bin or wheelbarrow if you need more volume. Use a shovel or a rake to combine all the ingredients. Your final product should be loose as you run your fingers through it.

You can also purchase premixed soil at your local nursery or on Amazon. Below are a few options to consider buying online.

Can I Use Topsoil In My Terrace Garden?

You can use topsoil in your terrace garden, but whether you should use it is the real question. If you don't have access to the first few inches of fertile topsoil, it can be purchased from a nursery or landscaping company. You might need to buy it in bulk, or perhaps you will find a bagged option.

Make sure the topsoil you are buying is loamy and screened of debris. To learn more about loamy mixes, read our post 11 Best Loam-Based Compost Mixes.
