Best days to plant
Learn the best days to plant by USDA zone, moon phases, and soil temperature. Get real dates, varieties, and tips for 2026.
The best days to plant depend on your USDA hardiness zone, the specific crop, and soil temperature, not on a single calendar date. For most vegetables, wait until the soil has warmed to at least 50°F for cool-season crops and 60°F or higher for warm-season crops. In 2026, plan to start cool-season crops like lettuce and peas 2 to 4 weeks before your last frost date, and warm-season crops like tomatoes and peppers 1 to 2 weeks after. Use a soil thermometer (around $10) to check, and adjust for your local microclimate.
Know Your Last Frost Date
Your last frost date is the anchor for all planting schedules. Find it by zip code using the USDA Plant Hardiness Zone Map or your local extension service. For example:
- Zone 5: last frost around May 15
- Zone 6: last frost around April 15
- Zone 7: last frost around March 15
- Zone 8: last frost around February 15
Count backward from this date to start seeds indoors, and forward to plant outside. For a spring garden, aim
to have transplants ready to go out within 2 weeks after the last frost.
Soil Temperature Matters More Than the Calendar
Seeds germinate when soil reaches a minimum temperature. Cool-season crops like spinach and radishes can sprout at 40°F, but warm-season crops like corn and beans need 60°F or more. Use a soil thermometer, insert it 2 to 3 inches deep, and check at 9 a.m. for a consistent reading. If the soil is too cold, seeds rot instead of sprouting. In 2026, expect soil to warm later in northern zones due to a cool spring, so be patient.
Moon Phase Planting: Does It Work?
Many gardeners follow moon phases, planting above-ground crops during the waxing moon and root crops during the waning moon. While there is no scientific proof, some report better germination. If you want to try it, here are the key moon phases for 2026:
- New moon: March 18, April 17, May 16 (good for leafy greens)
- First quarter: March 25, April 24, May 23 (good for fruiting crops)
- Full moon: April 2, May 1, May 31 (avoid planting, focus on weeding)
- Last quarter: April 9, May 8 (good for root crops)
Use these as a guide, but always prioritize soil temperature and frost dates.
Best Planting Dates by Zone for 2026
Here are recommended outdoor planting windows for common crops. Adjust for your local conditions.
| Crop | Zone 5 | Zone 6 | Zone 7 | Zone 8 |
|---|---|---|---|---|
| Peas | March 15 - April 1 | March 1 - March 15 | Feb 15 - March 1 | Feb 1 - Feb 15 |
| Lettuce | April 1 - April 15 | March 15 - April 1 | March 1 - March 15 | Feb 15 - March 1 |
| Tomatoes | May 15 - June 1 | April 15 - May 1 | March 15 - April 1 | Feb 15 - March 1 |
| Peppers | May 20 - June 5 | April 20 - May 5 | March 20 - April 5 | Feb 20 - March 5 |
| Corn | May 15 - May 30 | April 15 - April 30 | March 15 - March 30 | Feb 15 - Feb 28 |
| Beans | May 20 - June 5 | April 20 - May 5 | March 20 - April 5 | Feb 20 - March 5 |
For fall gardens, count back from your first frost date (usually mid-September in Zone 5, later in warmer zones) and plant cool-season crops 8 to 10 weeks before.
Best Days for Specific Crops
- Cool-season crops (lettuce, spinach, kale, peas, carrots): plant as soon as soil can be worked, usually 2 to 4 weeks before last frost. In Zone 6, that is late March to early April.
- Warm-season crops (tomatoes, peppers, squash, cucumbers): plant after all danger of frost, when soil is at least 60°F. In Zone 6, that is early to mid-May.
- Root crops (beets, turnips, radishes): plant directly in the garden 2 to 3 weeks before last frost. They tolerate cool soil.
Tools and Supplies for 2026
Invest in a few basics to make planting easier:
- Soil thermometer: $10 to $15, available at garden centers or online.
- Frost cloth: $15 for a 6x8-foot cover, protects young plants from late frosts.
- Seed starting trays: $15 for a 72-cell tray with dome, reusable.
- Garden planner app: $20 to $40 per year, like Planter or Gardenize, helps track dates.
Practical Steps This Week
- Check your last frost date using the USDA map or local extension.
- Buy a soil thermometer and test your garden soil in the morning.
- Start seeds indoors for warm-season crops if you have 6 to 8 weeks before last frost.
- Prepare your beds: add compost and ensure good drainage.
- For cool-season crops, plant as soon as soil is workable, even if frost is still possible.
FAQ
Q: Can I plant before the last frost? Yes, for cool-season crops like peas and lettuce. They tolerate light frost. Use frost cloth if a hard freeze is forecast.
Q: What if I miss the best planting date? You can still plant, but yields may be lower. Choose fast-maturing varieties, like ‘Early Girl’ tomatoes (60 days) or ‘Bush Blue Lake’ beans (50 days).
Q: Does planting on a full moon really matter? No scientific evidence supports it, but if it helps you garden, it is harmless. Focus on soil temperature and moisture.
Q: How do I know if my soil is warm enough? Use a soil thermometer. For warm-season crops, wait until it reads 60°F at 2 inches deep for three consecutive mornings.
The Bottom Line
The best days to plant are those when soil temperature and frost dates align with your crop’s needs. Use your last frost date as a starting point, check soil temperature, and adjust for your zone. In 2026, plan to start cool-season crops early and warm-season crops after the soil warms. With a soil thermometer and a simple calendar, you can maximize your harvest without guesswork.
