As spring unfolds, May brings an exciting opportunity for gardeners across the United States. The month is generally considered prime planting time, but what you choose to plant can depend significantly on your local climate zone. This guide will help you understand what vegetables, herbs, and flowers thrive based on where you live, ensuring your garden flourishes this season.
Understanding Climate Zones
Before diving into specific planting options, it’s essential to understand the USDA hardiness zones. These zones categorize different regions based on temperature and climate conditions, allowing you to select plants that are well-suited for your area. The USDA has divided the U.S. into ten different zones, ranging from the cold climates of Zone 3 to the warm conditions of Zone 10.
What to Plant in Northern Regions (Zones 3-6)
In the cooler northern areas, May marks the transition into warmer weather, making it ideal for planting a variety of vegetables and flowers. Here are some great options:
Vegetables
- Tomatoes: These sun-loving plants thrive when planted after the last frost.
- Peppers: Both sweet and hot varieties can be planted now for a summer harvest.

- Squash: Try planting both summer and winter squash for variety.

General Planting Tips for May
Planting Seedlings
May is an excellent time to transplant seedlings that were started indoors, such as tomatoes and peppers. Ensure you’re planting after the last frost date to give your seedlings the best chance of thriving.
Direct Sowing
Many crops, including beans, squash, cucumbers, and corn, can be directly sown into the garden. This method allows plants to establish themselves in their permanent home from the beginning.
Flower Planting
May is also an ideal month for directly sowing a variety of summer flowers. Consider creating colorful flowerbeds that will bloom throughout the season, attracting beneficial insects to help pollinate your plants.
