The best garden cold frames in 2023 (2023)

Somewhere between a large cloche and a small greenhouse, cold frames are protective enclosures which provide invaluable protection for seeds, cuttings and tender plants, especially during cold months.
Cold frames can make a gardener's early spring and autumn much more active for growing, allowing peas and beans to get off to an early start, or giving tender young plants time to harden off, ready for the summer months.

How to choose a cold frame.

Cold frames are made from a number of different materials:

  • Glass cold frames are often the most expensive and they are fragile, as glass breaks easily but they let in more light than other materials allowing in the most light.
  • Cold frames with polycarbonate panes are cheaper than glass and longer lasting but they don't allow in as much light.
  • Wooden cold frames tend to provide regular temperatures and are strong and sturdy but the wooden frame will need some regular maintenance to prolong its life.
  • Aluminium cold frames are light and long-lasting, but may be expensive.

Cold frames are versatile and can be modified to better suit your plant’s needs. Whether you’re looking to insulate your cold frame as you would a greenhouse, or even just add a splash of colour, if you can’t see a cold frame that suits all your needs, browse our DIY section for instructions on how to make your own.

Victorian grow house - rectangular

The best garden cold frames in 2023 (11)

A feature of this cold frame that we particularly enjoy is that its sides, tray, lid and base are all separate components, and may be adjusted to the user’s needs, whether it’s providing bonus ventilation via removing the lid, converting the cold frame from standing to ground-level by removing the legs, or simply removing the walls and using this cold frame as a handy garden shelf. It’s a small detail, but one that makes the Victorian Grow House frame far more versatile than the average cold frame!
