We have coldframes for sale! With a coldframe, you can eat your own salads in April, keep greens going through the winter, start seeds at all times of year and more!

Set it up in a sunny spot, facing south, and garden year round.

But maybe you don’t have the time or skills to build a coldframe.

Blockhouse School Project to the rescue.

Myk has been building coldframes from re-purposed materials and will be selling them at the Farmers’ Market when it starts in May.

If you want one sooner, get in touch with email hidden; JavaScript is required.

And if you’re wondering what to do with a coldframe, check out Niki Jabbour’s excellent book, The Year-Round Vegetable Gardener: How to Grow Your Own Food 365 Days a Year, No Matter Where You Live. Niki lives around Tantallon, Nova Scotia, so if she can grow it, so can we at Blockhouse.

The big advantage of a cold frame over a mini hoop tunnel, which is also useful for extending the growing season, is convenience: it’s easier to access in the middle of winter when ice and snow make it hard to get into the tunnel. Just sweep snow off the coldframe to let the winter light in, except during cold snaps when the snow actually helps to insulate the plants. For best results, harvest when the temperature inside is above freezing.
