Cold FrameCold frames are ideal for protecting young and delicate plants from harsh weathers such as strong winds, snow and frosts. A cold frame can function as a mini greenhouse to prolong or extend the growing season. Our Box Cold Frame uses 4ft, 2ft and 1ft 6in poles, meaning it is large enough to provide useful cover and protection for a variety of plants, but also light and compact enough to easily move around the garden as required.
