Growing Palm Trees in Delaware's Unique Climate
Delaware may not be the easiest place to cultivate palm trees, but with some careful planning and knowledge of the climate, it can be done. This small state's wet, semitropical, and continental climate presents challenges, but the influence of the ocean helps palm trees thrive even in the winter months.
The southern half of Delaware enjoys a milder climate compared to the northern part. July sees average temperatures of about 76°F (24°C), while January averages around 31°F (–1°C). Despite these moderate temperatures, Delaware has experienced both extreme highs of 110°F (43°C) and lows of –17°F (–27°C). This variation in temperature is important to consider when selecting palm tree species.
