Choosing the right peppers for your garden starts with understanding the difference between sweet, mild, and spicy varieties. This guide will help you select the best cultivars for your climate and cooking style.
The Sweet Spectrum Bell peppers are the most popular sweet peppers for US gardeners. They reach maturity in 60 to 90 days and thrive in soil temperatures above 70°F. For smaller containers, look for 'lunchbox' or 'snack' varieties that provide high yields on compact, 18-inch plants. These peppers lack capsaicin, the compound responsible for heat, making them a safe choice for every gardener.
Understanding Heat Levels Heat in peppers is measured by the Scoville Heat Unit (SHU) scale. Mild peppers like Poblanos register low on the scale, while jalapeños pack a moderate punch. If you are new to growing chiles, consider these heat tiers:
- Mild: Shishito and Poblano (great for roasting or stuffing).
- Medium: Jalapeño and Serrano (the backbone of fresh salsas).
- Hot: Thai bird’s eye or Habanero (use with caution in the kitchen).
Tip: Always wear gloves when harvesting and handling peppers with high SHU ratings, as the oils can linger on your skin and cause irritation to your eyes or nose.
