Here are seed-starting dates for your first spring planting. These dates are based on historical frost dates, as reported by your nearest government weather stations.
Historical data is useful way to get a sense of "typical" frost dates to give you a general sense of timing. However, it is not a replacement for good judgement. Obviously, you need to be aware of your weather this coming season. Other factors that can also influence your planting dates include soil temperature, altitude and slope of land, nearby waters, and day length. Also, keep records of your garden's conditions each year to plan more accurately.
On chart below, please note:
- Seeds for plants with a long growing season should be started indoors during the periods shown below.
- Seeds for plants sown in the ground should be planted during the periods shown.
- When no dates appear in the chart, that starting method is not recommended for the particular vegetable.
