Climate Considerations Across Massachusetts

Along the coast, zones 6 and 7 have milder winters Inland and at higher elevations, zone 5 brings colder winter temperatures Across the state, rainfall is consistent year-round.
These factors impact optimal bulb planting times. Understanding your microclimate helps select appropriate bulbs and target the seasonal windows for planting and blooming.
When to Plant Spring and Summer Flowering Bulbs
For bulbs that bloom in spring and summer, the ideal planting time is autumn. Specifically, aim to plant bulbs from late September through November.
This window allows enough time for root establishment before the ground freezes. Well-developed roots by early winter let bulbs rest through the colder months and gear up to flower as temperatures rise.
You can also plant bulbs in early spring, but they won’t bloom until the following year. Focus on planting in spring once the soil warms up, usually early to mid April.
Target Soil Temperature
Soil temperature is an important indicator for bulb planting times. In autumn, target soil temps between 40-50°F for optimal root growth. For spring, wait until soils reach at least 60°F before planting.
Investing in a soil thermometer takes the guesswork out of determining if soils are ready. Measuring temperature at the desired bulb planting depth ensures you catch the ideal window.
