A double skinned wall provides an air pocket of insulation that minimizes the temperature fluctuations and drying out of the soil in the garden bed. Sometimes raised bed gardens are covered with clear plastic to protect the crops from wind and strong rains.
Because these beds are sitting above the ground it permits the air to circulate around the containers and allows the sun to warm them up quicker. This will allot for earlier planting and quicker germination especially in the colder climate areas.
our limitations will go as far as your imagination takes you and the area of space you have to work the garden. There are raised garden bed kits available for purchase at some nurseries, home and garden centers, or on-line.
Raised garden beds add new measures to the experience of gardening. Garden beds that we raise above the ground give the gardener with just a balcony a place to grow flowers or a vegetable garden.
