What is a cold frame? The best description is a mini glasshouse which is low to the ground. You can check out one from Gardening Australia here. They are predominately used in much colder climates than ours, however, the primary reason that we built one is that I want to grow basil throughout the winter months. It will also be perfect for starting spring seedlings a bit earlier than usual.
For the past few weeks we have been taking small steps towards building a cold frame.
Two hardwood sleepers form the back wall.
Deciding on a location, sourcing materials (the majority secondhand) and developing a design have all taken time. GMan has cut and painted timber as well as replacing putty in the window frames.
Everything has moved up a notch in the last couple of days as we began building in earnest.
The construction is almost complete with only the polycarbonate sheeting to be added to the front and ends of the enclosure. This last step is on hold until we retrieve our jigsaw (lent out recently) to cut the sheeting. Hopefully this will happen early next week.
We won’t win any prizes for our carpentry skills but the structure is solid and functional.
A pair of casement windows from the timber salvage yard form the top of the cold frame. They are hinged at the back and we attached some old cupboard handles to the front edge to facilitate easy access.
Apart from the polycarbonate sheeting on the sides, we also need to finish levelling the ground and filling the holes around the uprights.
In the meantime I have put the tray of basil seedlings in this space overnight as even without the sides completed it still offers a warmer and more protected space than their previous location.
The components which we purchased new for this project were the sleepers, hinges, window putty and long screws for the frame. The windows, handles and timber all came from the salvage yard while the screw used with the hinges and handles came from our collection of odds and ends at home.
I would love to hear of anyone else’s experience with a similar kind of set-up.
