Cold Frames have been used for centuries to propagate plants, in fact the first glasshouses were no more than glorified cold frames, gently sloping glazed and timber panels set upon stone or brick walls designed to protect tender plants. A Cold Frame is sometimes referred to as a cloche, a propagator, a garden frame or ironically a hot frame where heating would have been provided by farmyard manure.
Cold Frames for gardens are almost indispensable, there are times in the lives of all the more familiar greenhouse plants that the glasshouse is too warm for them, there are seasons of the year when there is almost always overcrowding unless overflow accommodation is available, for those who have limited space in their gardens then the Cold Frame gives invaluable space to overwinter, encourage plants or propagate. Last but not least when seedlings are raised in warmth for subsequent planting out it is not possible to harden them off without the use of a garden frame.
If you use your cold frame for early cropping then maximum roof glazing to captivate the sunshine is vital, but because of its portability a cedar Cold Frame can be re-positioned to a north facing position in the summer to protect and encourage autumn and winter flowering plants. You will wonder how you ever managed without a Gabriel Ash Cedar Cold Frame. Gabriel Ash also have a range of cedar greenhouses available to buy online.
