Homemade Coldframe for Snuggly Plants

I’d been wanting to make a coldframe for seeds, seedlings, and cuttings for some time. The benefits of making your own coldframe are:

  • You get to use tools and speak like a builder
  • You can start propogating things earlier and get them into the ground faster
  • You can upcycle stuff that would normally be dumped
  • You can grow plants for free (cuttings) with more success
  • You can grow more from seed, which is far more economical than buying baby plants

Our neighbour (who has an awning-making business) gave me loads of thick clear plastic offcuts the other day. It looks like the stuff that windows in those big 1970s family tents are made from. Perfect for keeping warmth in and frost out. I had seen the stuff in use as an awning during Friday arvo drinks with the School Mums a while back, and specifically asked for any free bits with a coldframe in mind. If you don’t ask, you won’t receive.

I found an old bookshelf and suitcase at EcoShop yesterday. This morning we (I made this into a family event) flipped the bookshelf on its back, removed the extra slats, repositioned a piece to help keep the plastic up in case of snow, and screwed the plastic onto one side of the case. We used a manual screwdriver as the shelf is just pine. I can fold the plastic back or prop it up at the sides on warm days to keep it ventilated, and cover it back up at night. It’s very heavy, so it won’t blow around.

I haven’t quite figured out how to dismantle the suitcase yet, so in the meantime I’ve chucked my taller cuttings in it and it’s positioned under the porch.

If you don’t have a neighbour who has an awning business, you can use cheap windows from a reclamation yard, although you need to be able to move them aside on hot days. If you Google ‘Coldframe’ images, you can see loads of ideas.
