Cold Frames

Our Cold frames for gardening provide valuable extra space for young or overwintering plants if your greenhouse is full, also they’re a good option if you don’t have room for a greenhouse.

Available in a variety of materials and finishes, our range of cold frame greenhouses includes wooden cold frames, aluminium cold frames, polycarbonate cold frames and glass cold frames. In early spring a cold frame is an ideal ‘half-way house’ between greenhouse and garden for plants that need hardening off. Cold frames are best suited against a sheltered south-facing wall or fence to get as much heat and light as possible. When choosing a cold frame, make sure the lid can be propped open for good ventilation during the day.

Expert advice from Jackie Whittaker, garden writer for Garden News - A cold frame can open a new dimension in gardening, giving the benefits of a longer season, enabling you to grow earlier, later, bigger and better crops, as well as raising more of your own flowers and shrubs. A cold frame can also be a halfway house for plants in the spring, when they move from the warmth and protection of your greenhouse into the cooler conditions of your garden. A cold frame provides you with a place to ‘harden-off’ these young, tender plants before you plant them out. Let your plants get used to the cooler conditions, leaving the cold frame lid closed for the first few days and then starting to open the frame to get the plants used to cooler temperatures. About two weeks in a cold frame usually prepares your plants sufficiently to be planted into your garden.
