Does The Raised Garden Bed Need to Be Buried?

If you live in an apartment or rental property, or the soil around your house is not suitable for planting plants, it is a good choice to have a raised garden bed. However, you may have reservations about using this gardening technique to grow plants on balconies, driveways, terraces, or other similar places.

Raised garden beds do not have to be buried in the soil to grow plants. They need a strong base frame to stay on concrete, asphalt, wood, tiles and other similar materials. However, they need good drainage to prevent root rot and other plant diseases.

Should you bury a raised garden bed?

Raised garden beds look great on your property, especially when you don't have enough space to grow a variety of plants. However, you may wonder if it is a good idea to bury them.

You don't have to bury a raised garden bed, especially on hard landscapes such as concrete, asphalt, tiles and wood. As long as there is enough drainage to prevent water from accumulating in the soil, the solid bottom frame can work.

The beauty of raised garden beds is that you can put them almost anywhere as long as you make sure they receive enough sunlight and have a sound drainage system.

Although water is an excellent resource for keeping plants alive, too much water in the soil can cause several problems.

It is important to remember that roots, like leaves, need oxygen to survive. Air exists in small pockets in the soil, called soil pores.

When the soil has too much water, it will reduce the amount of oxygen available to the root due to the lack of proper drainage system.

Over time, too much water will lead to plant diseases. In addition, root cells die due to hypoxia, leading to the final death of plants.

Factors to consider when installing raised garden beds

Suppose you have a driveway and want to open a vegetable garden or plant ornamental plants to beautify your property. In this case, a raised garden bed is a good idea.

However, it will help if you remember the key factors to consider when installing a raised garden bed (i.e. Drainage and size).


In terms of drainage, it is beneficial to keep the bottom open. It allows excess water to flow, ensuring that the soil is not flooded and suffocating plants.

On the other hand, an open bottom frame increases the risk of soil falling off the garden bed, especially if it is raised. You want to avoid this situation because it reduces the soil volume over time. In addition, the precious nutrients on which plants thrive will slowly seep out with the soil.

When using the metal cloth, do not put it at the bottom of the raised garden bed. Make sure to leave some space at the foot of the bed.

In addition, you should use landscape fabrics to keep the soil in place. Fold it on the hardware cloth, you can go there easily.

If the water keeps falling on your hard ground, it will leave stains. There are two solutions to this problem.

One option is to use an electric washing machine, which can easily remove water stains.

You can also use drip pans to collect out of control water.

However, depending on how often you water the plants, you may have to drain them often.

Asphalt and concrete

As I mentioned, the drainage of the raised garden bed plays a vital role in the healthy growth of your plants. If the garden bed drains too quickly, the roots of the plants will not get the water they need, causing them to die.

Fortunately, you do not need to close the bottom of the frame for asphalt and concrete floors.


When it comes to the wooden surface of a balcony, deck or terrace, drainage is essential. Although these materials may have been extensively treated to prevent decay, this is still a problem if their surfaces are kept moist for a long time.

In this case, you must close the bottom frame of the raised garden bed. However, make sure there are enough holes for water to seep out of the setting.

You should also use a drip tray to prevent water from falling on the wood floor. Empty the tray regularly to avoid water spillage.

As long as you can prevent water from flooding the soil, you can plant a lot of plants and enjoy gardening.
