Step 1: Know Your USDA Hardiness Zone
Before diving into planting dates, identify your USDA Hardiness Zone . This map divides the U.S. into 13 regions based on average minimum winter temps. Why does this matter? Plants labeled “perennial” in Zone 8 might be annuals in Zone 5. Check your zone here to tailor your calendar.
Pro Tip: Pair this with local frost dates (available via your state’s Cooperative Extension Service ) for precision.
Spring Planting Guide (March–May): Start Small, Dream Big
Spring is all about preparation and cool-season crops. Here’s what to prioritize:
Early Spring (March–April):
- Vegetables: As soon as soil thaws, sow seeds for lettuce, spinach, peas, and radishes. Transplant kale and cabbage seedlings.
- Herbs: Chives, parsley, and cilantro thrive in cooler temps.
- Tasks: Test soil pH, amend beds with compost, and start tomato/pepper seeds indoors 6–8 weeks before your last frost date.
Late Spring (May):
- Warm-Season Crops: Plant tomatoes, peppers, cucumbers, and beans after the last frost. Use row covers if cold snaps loom.
- Pollinator Boost: Add marigolds or sunflowers to attract bees.
Summer Planting Guide (June–August): Sow for Succession
Keep your garden productive with smart summer moves:
Early Summer (June):
- Direct Sow: Carrots, beets, and bush beans. Use shade cloth to protect delicate seedlings.
- Transplants: Eggplants, zucchini, and squash.
Mid-Summer (July–August):
- Succession Planting: Re-sow quick-growing crops like lettuce, spinach, or green beans for a fall harvest.
- Herbs: Basil, dill, and mint love summer heat.
Critical Task: Water deeply during heatwaves and mulch to retain moisture.

Fall Planting Guide (September–November): Extend Your Harvest
Fall gardens are underrated! Focus on cool-season crops and soil health:
Early Fall (September):
- Direct Sow: Broccoli, cauliflower, and kale. Start garlic cloves for next year’s harvest.
- Transplants: Brussels sprouts and autumn-harvest tomatoes.
Late Fall (October–November):
- Protect Plants: Use cold frames or hoop houses for spinach, arugula, and winter lettuce.
- Cleanup: Remove spent plants to prevent disease.
Bonus: Plant a cover crop (like clover) to enrich soil over winter.

Winter Gardening (December–February): Plan, Don’t Pause
Even in cold regions, winter isn’t a gardening dead zone:
Indoor Tasks:
- Order seeds (we recommend Johnny’s Selected Seeds ), sketch next year’s layout, and sanitize tools.
- Start herbs or microgreens in sunny windowsills.
Outdoor (Mild Climates):
- In Zones 7–10, direct sow onions, carrots, and Asian greens.
Pro Tip: Use Plantify’s Winter Sowing Guide to prep like a pro.

A: Staggering plantings every 2–3 weeks to ensure continuous harvests. Perfect for lettuce or beans!
Q: How do I adjust dates for climate change?
A: Track local phenology (e.g., when native plants bloom) and pair with USDA zones for accuracy.
