A cold frame is a very useful piece of garden kit – it can be used for sowing seeds, hardening off young seedlings in spring, taking cuttings, growing early and late crops such as winter salad and shielding plants such as succulents and alpines from winter wet.
You can make your own cold frame cheaply and easily. Here, we have used a standard 100cm x 120cm pallet to create the base and an old window, 115cm x 130cm to make the top.
Forming beautiful rosette patterns, this colourful collection of sempervivums (houseleeks) is a must-have for any garden. Native to alpine regions, they're tolerant to extreme temperatures and drought.
