Why Zone 6-8 Is the Gardening Sweet Spot
- Four distinct seasons allow for rotation between cool-season and warm-season crops.
- A wide range of ornamental shrubs and trees survive winter without extreme protection.
- Soil freezes in winter, which naturally breaks pest and disease cycles.
- Warm summers support heat-loving vegetables while cold winters provide the chill hours fruit trees need.
