When to Plant in Green Bay, WI

Green Bay, Wisconsin, experiences its last spring frost on May 6 and its first fall frost on October 4, resulting in approximately 151 frost-free days each year. This gives local gardeners a relatively short but productive growing season. With these dates in mind, it's crucial to plan plantings carefully to maximize the yield from your garden. Timing is especially significant when it comes to sowing seeds and nurturing young plants, as successful gardening relies heavily on understanding these frost dates.

The microclimate in Green Bay is classified as a humid continental Great Plains environment. This climate is conducive to growing a variety of crops, particularly cool-season vegetables like lettuce, kale, and peas, which perform exceptionally well in the spring before the heat of summer sets in. Conversely, crops like melons and sweet potatoes may struggle due to the relatively short growing season, as they require longer and warmer conditions to thrive successfully. The summer heat can be beneficial, but the early frost threatens these heat-loving plants.
