Charlottetown Climate Notes
PEI is Canada's potato capital — growing potatoes here connects to the island's agricultural identity. Island cool maritime summers are ideal for root vegetables. Sandy loam soil drains well and warms faster than mainland clay soils, giving PEI gardens a head start in spring that partially offsets the cool summers.
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.
