Greenhouse Gardening: Garden Bed Designs
Constructing Planting Beds in a Dome Greenhouse
For those of you who may be considering building a greenhouse dome kit from Growing Spaces, we provide a selection of pictures from Growing Dome owners of their garden bed designs.
In the Growing Dome, usually there is an outer raised bed, a circular pathway, and then an inner raised bed. The beds generally are anywhere between one and two foot high depending on the personal preference of the owner and raised bed design is entirely up to the owner of the Growing Dome. Over the years, we have found our owners use recycled plastic lumber, Douglas Fir, plywood, sheet metal, adobe, rocks, and many other methods of creating the walls for the raised beds.
The pathways can be of bark chips, gravel, flagstone or brick pavers. However, what we have found is that in order to maintain moderate temperatures, especially in the summer, that luxuriant plant growth shades the soil thus helping to keep the dome cool. If there are large expanses of rock or brick, which is not shaded, this can heat up quite significantly in the day, thus creating overheating in the dome greenhouse.
