Understanding Zone 4b

Zone 4b is a subarctic climate zone that experiences long, cold winters and short, cool summers. The average minimum temperature in this zone ranges from -25°F to -20°F (-31°C to -29°C) and the average maximum temperature ranges from 75°F to 80°F (24°C to 27°C). This means that the growing season is limited to around 90 to 100 frost-free days, which makes it essential to plan your planting schedule accordingly.

Soil Preparation

Before you start planting, it is important to prepare your soil. The soil in Zone 4b is typically heavy and clay-like, which can make it difficult for plants to grow.
