Want to keep growing your greens well into winter? The easiest solution is to build your very own cold frame.
A cold frame is a simple system that protects seedlings from the cold & wind, while at the same time
capturing the warmth of the sun to help them grow. It maintains a warm & damp environment that is
perfect for seed propagation. An added bonus of a cold frame is protection from flying bugs.
To construct the cold frame you’ll need;
- An old window frame, with glass intact
- 4 pieces of wood to make the base – these pieces should match the lengths of the window frame
- Hinges for joining the base & the frame
- Hand or circular saw
- Electric drill
The process of construction is relatively simple. Pre-drill holes in your base lengths (pre-drilling will reduce the chances of the wood splitting when you screw into it). Screw the base lengths together until all 4 pieces are connected and you have a frame. Then line the window frame up and screw in your hinges; and that’s it, you’ve made yourself a cold frame.
The system can also be used to grow salad greens and other small vegetables all year round, particularly if you’re in a colder climate.
