Pennsylvania planting dates
Pennsylvania raised bed planting dates
Pennsylvania has meaningful climate variation from colder northern and mountain areas to milder southeastern gardens. Treat statewide timing as a starting point, not a fixed calendar.
Cool-season window
Peas, spinach, lettuce, radishes, carrots, beets, onions, kale, and cilantro are common early-season raised-bed crops when soil can be worked.
Warm-season window
Tomatoes, peppers, basil, beans, cucumbers, and zucchini need warmer conditions. Western and northern areas may lag southeastern Pennsylvania by days or weeks.
Fall planting
Late summer is a second planning season for quick greens, radishes, carrots, beets, cilantro, peas, and kale.
Do not rush tomatoes
Cold nights can stall tomatoes and peppers even after the last frost.
Use finished space
Replace spring crops quickly so beds stay productive through summer and fall.
Frequently asked questions
When should I plant vegetables in Pennsylvania?
Cool-season crops can start earlier in spring, while warm-season crops should wait until frost risk has passed and nights are warmer. Exact dates vary by county and elevation.
What USDA zones are in Pennsylvania?
Pennsylvania spans multiple USDA zones, so local frost dates are more useful than a single statewide planting date.

Next step
Pick the month closest to your planting window, then calculate spacing before filling the bed. Open the calculator with these defaults, or check the monthly sowing calendar before you plant.
