ABSTRACT:
A plant propagation unit has a continuous wall encircling the bed to protect the plants from high wind and dust, and is preferably spaced a short distance above the bed to permit escape of water from the bed and flow of air under the wall and upwardly through its open upper end. To facilitate tending the plants and bed, upper portions of the wall may be removable or hinged so that they can be swung downwardly to lower the overall height of the wall. A top spaced above the top of the wall and the bed facilitates ventilation of the bed and the plants therein, while protecting the plants from frost or intense midday sunlight as well as from heavy rainfall. While the top may be of any suitable type depending on the area in which the plants are being grown, it is preferably of a slightly open material, such as roll bamboo fencing, to permit a limited amount of sunlight and rain to enter the bed. The top is preferably removably hinged to uprights.
