Building Raised Beds for Short Canadian Seasons
Why raised beds warm earlier in a cold spring, sensible timber and dimensions, and how depth interacts with frost in the soil.

Vegetable gardening notes for short, frost-bracketed seasons
Brick Hearth Co collects working notes on the parts of vegetable growing that decide a Canadian harvest: how beds are built, which crops shrug off frost, how soil is fed, and how one bed produces more than one crop between the last spring frost and the first hard freeze.
Reading order
Three notes, in the order a season unfolds
Selecting Frost-Resistant Vegetables for Cold Zones
Crops that tolerate light frost at both ends of the season, and the difference between hardy, half-hardy and tender groups.

Soil Amendment and Succession Planting
Feeding bed soil with compost and organic matter, then using the warmed weeks for a second and third sowing.

Why the focus
Canadian seasons are short and bracketed by frost
Across much of Canada the frost-free window is measured in weeks rather than months, and the date of the last spring frost and the first autumn frost varies widely between regions. The notes here treat that window as the central constraint, because most decisions in a vegetable bed follow from it.
- Planning sowings around local frost dates rather than calendar months.
- Building beds that warm quickly so roots start sooner.
- Choosing crops by their tolerance to cold, not only by taste.
- Keeping soil fed so a bed can carry more than one crop.
