Their advantage is not only that they enable very body-friendly gardening. The raised bed greenhouse offers plants ideal growing conditions and allows the soil to be replaced much more easily than is the case with ground-level construction. And you can build it yourself too!
Why is a raised bed greenhouse beneficial?
A raised bed greenhouse offers ideal growing conditions for plants, enables easier soil exchange and back-friendly gardening. The optimal planting consists of a drainage layer, soil layer, middle core layer and sifted compost. Care includes regular freshening and soil sample analysis.
Similar to outdoors, the raised bed greenhouse has proven itself thousands of times over as a weather-independent variant for growing plants. Well thought out and with a stable superstructure towards the walls, the available interior space in such houses can be used particularly well. If theside height is maximized according to the height of the raised bed, there is still enough room for larger plants. Other advantages include:
- faster and usually more productive growth of the plants because their roots are always in warm soil;
- Raised beds can be attached to a separate foundation (strip foundation or ground anchor), which significantly increases the statics and safety of the entire structure;
- Extremely back-friendly gardening is possible in the raised bed greenhouse;
- Replacing the floor is significantly easier than with ground-level construction and can even be done in layers with different materials;
Material for the raised bed construction
Complete raised bed greenhouses are available in stores, as well as prepared prefabricated wooden parts that just need to be put together and screwed together, and if you feel like it, you can easily get these practical wooden structures yourself assembledIt works best withhigh-quality larch wood, which is connected to stabilizing posts at the corners. The material thickness can be a little more massive, as the internal pressure of the soil in the raised bed can be quite high.
Proper gardening requires good soil in the raised bed greenhouse
Not just high-quality soil, but the different types of soil enable your vegetables and all the other plants to thrive. However, thedifferent growing conditions of the planned planting must still be taken into account. The following constellation (order from bottom to top) is generally recommended for traditional vegetable and herb cultivation:
- Drainage layer: Consists of coarser clay shards and pebbles that become smaller and smaller in height; Water backups are kept within limits or completely avoided;
- Soil layer: A 10 to 15 cm thick layer of soil from the garden floor is recommended;
- Middle core or wood layer: This is where the shredded remains from the last trimming of the bushes go (not chopped too finely!) as well as a portion of well-rotted, i.e. ripe, compost, if possible with an addition of stable manure;
- Sifted compost: This layer provides the nutrients needed by the plants and contains thoroughly sifted compost from our own production.
Please note that only high-quality compost soil is used, otherwiseincreased rot formation can occur, which has a negative effect on the growth of the plants.
Caring for raised beds in the greenhouse
The top layer can be refreshed a little after each harvest. This guarantees that there is always a balanced ratio of nutrients in the soil. Overall, the contents and thus also the height in the raised bed will be reduced by around 10 to 15 cm, so that it should be refilled again and again up to the second level before all layers are completely replaced after five to seven years.
Tip
Similar to outdoors in the garden, regular soil samples should be taken from the soil in the raised bed greenhouse and evaluated in the laboratory. A quick test that at least provides information about the current pH value also provides valuable information in this regard.
