Classic raised bed without floor contact
The lack of a floor in a conventional raised bed ensures that excess irrigation and rainwater can drain away unhindered. If there is no ground contact, the water can build up inside the bed - the plants are literally drowned. Nonetheless, direct contact with the ground is not absolutely necessary if you want to prevent waterlogging in some other way - for example by making drainage holes on the side walls (if the bed is on the terrace, for example) or simply by providing rain protection (for example with a plexiglass roof).

- Can you build a raised bed without a foil?
- Can you just fill a raised bed with soil?
Raised table beds for balconies and patios
If you don't want to do without the practical gardening in the raised bed despite the lack of a garden, you can fall back on the practical raised table beds on the balcony or terrace. These are flat raised beds without any contact with the ground, as the plant container is well above the surface. These special raised beds have been specially designed for the static requirements of a balcony for which a conventional raised bed is too heavy. However, raised table beds can only be filled with soil (and not in a layered system like a normal raised bed), as the space available does not allow composting. But table beds offer a whole range of other advantages:
- they are light and easy to transport
- they can be quickly moved to another place - even if they are currently planted
- they don't take up much space and are also suitable for small balconies
- but still offer more planting space than conventional planters
- You save yourself the complicated filling of the raised bed
Accessible raised beds for wheelchair users
Furthermore, wheelchair users and seniors who are no longer very good on foot must also forego gardening in the raised bed. The wheelchair-accessible raised beds were specially developed for these gardening enthusiasts. They are recessed either on one or two sides so that a wheelchair or another seat can comfortably fit underneath. These raised beds also usually have little or no contact with the ground.
When watering raised beds that are not in contact with the ground, make sure that you do not water the plants through - the lack of drainage means that excess water cannot run off.
