The best position for your cold frame in any garden is in a south facing position, with good protection from the wind and great drainage. A huge problem for plants when growing is lack of water drainage so this is a key consideration. It is highly beneficial for the rear end of a cold frame to be slightly higher up than the front of the frame, although this is not essential it’s beneficial from a drainage perspective.

How do I use my cold frame?

You will need to keep an eye on the ventilation of your cold frame. Whilst they’re fantastic for preserving your plants against harsh weather, you will still need to ventilate. One item found useful when owning and looking after a cold frame is an automatic vent controller, this will automatically open and close your cold frame when the temperature starts to rise and fall. Be sure to keep the lid open on a very hot, sunny day, whilst trapping the heat inside ready for a cooler night.

If you’re in need of more heat over the cooler months, you can use electric heating cables underneath or a layer of mulch, compost, or manure under the topsoil if you prefer a non-electrical solution to providing more heat for your plants. Remember, the cooler the conditions, the more slowly your plants will grow, and vice versa.
