Direct sowing means planting seeds straight into garden soil. Transplanting means growing seedlings indoors first, then moving them outside once conditions are right. Crops like carrots and beans prefer direct sowing. Tomatoes and peppers do better with an indoor head start, especially in shorter growing seasons.
They are based on USDA zone data, NOAA 30-year frost averages, and university extension recommendations. For a typical year, they will be close. But microclimates, elevation, and unusual weather can shift actual frost dates by a week or two. Always check local forecasts before planting frost-sensitive crops.
Yes. The calendar includes fall planting for garlic, and cool-season crops like lettuce, spinach, and kale can often go in again in late summer for a fall harvest. Those windows are calculated from your first fall frost date.
Zone data comes from the USDA Plant Hardiness Zone Map (2023 revision). Frost dates come from NOAA U.S. Climate Normals (1991-2020 averages). Planting schedules are cross-referenced with university cooperative extension programs including Clemson, Cornell, UMN, UC Davis, and Texas A&M.
