Start indoors 8–10 weeks before last frost. Germinate at 26–30 °C on a heat mat; peppers stall below 22 °C. Pot up to 10–15 cm before hardening off outside after nights stay above 12 °C.
Feed balanced through bloom, then bump potassium for fruiting. Stake taller varieties. More detail in our full Canadian growing guide.
Match the pepper to the technique: thin-walled varieties blister fast in a hot pan; thick-walled ones roast or stuff beautifully; fruit-forward ones make balanced sauces and pickles. The variety's flavour profile is your shortcut — see Choosing the right pepper for a use-case guide.
