2010 Best Planting Dates for Seeds for Dublin, New Hampshire

The last spring frost date is a key date for planting your garden seeds—it tells you when it is safe to plant in the ground. However, there are other factors influencing planting dates, including type of soil, altitude, nearby waters, slope of land, and day length. Your average frost dates may be different by a week or two. Keep in mind that these are general guidelines; keeping records of your own garden's conditions each year will help you plan more accurately.

If planting by the Moon, note that above-ground crops are planted during the light of the Moon (new to full Moon); below-ground crops are planted during the dark of the Moon (from the day after it's full to the day before it's new again). Planting is done during the daytime in these periods. Planting at night is optional!

Note: The chart covers the most popular crops; for others, please consult your local cooperative extension. Blanks in the chart indicate that we do not recommend starting some seeds indoors or, conversely, we only recommend starting some seeds indoors.
