Understanding your planting zone is essential for successful vegetable gardening. Each zone has different climate conditions that influence when and how to plant specific vegetables. The lower the zone number, the colder the region, meaning some vegetables must be started indoors before being transplanted outdoors.
This guide provides a zone-based planting schedule for common vegetables and essential tips to maximize your harvest!

📍 Understanding Planting Zones
The USDA Hardiness Zone Map divides North America into zones based on average winter temperatures. Knowing your zone helps you plant at the right time and avoid damage from frost.
✔ Zones 3-4 → Cold climates with short growing seasons
✔ Zones 5-6 → Moderate climates with defined seasons
✔ Zones 7-8 → Warm climates with long growing seasons
