Red Deer Climate Notes
Red Deer has one of the shortest growing seasons of any major Canadian city. Focus on cool-season crops that thrive below 20°C. Raised beds warm soil 4-6°C faster in spring — effectively extending the season by 2 weeks. Cold frames and row covers are essential tools.
Growing Tips for Beets
- Soak beet seeds 4 hours before planting to soften the tough seed cluster and improve germination rates.
- Thin seedlings to 3 inches apart — crowded plants produce tiny woody roots rather than full-sized beets.
- Use thinnings as baby greens in salads; beet greens are more nutritious than the roots.
- Harvest when shoulders reach 1.5–3 inches wide; larger beets develop woody cores and bitter flavor.
