Preparing your garden for spring can begin even in the depths of winter. By carefully selecting plants that will emerge and thrive in the spring, you can maximize your garden’s potential. This month-by-month guide outlines what to plant now, taking into account the specific gardening zones and what will provide vibrant blooms and harvests come spring.
Understanding Zones
Before you start planting, it’s crucial to know your USDA hardiness zone. Knowing your zone helps identify what plants will do well in your area. The map categorizes regions based on their climate, with each zone representing a range of average annual minimum temperatures. Here’s a quick overview of the zones:
Zone 1: -60°F to -50°F
Zone 2: -50°F to -40°F
Zone 3: -40°F to -30°F
Zone 4: -30°F to -20°F
Zone 5: -20°F to -10°F
Zone 6: -10°F to 0°F
Zone 7: 0°F to 10°F
Zone 8: 10°F to 20°F
Zone 9: 20°F to 30°F
Zone 10: 30°F to 40°F
Zone 11: above 40°F
