Spring is officially here, although it may not feel like it! For those of you in Chester County who are anxious to start your spring planting and mulching, please reference this landscaper frost date tool to find out average frost dates. Remember to cover anything you plant if the temperature reaches below 33°.

It’s important to remember that the average last spring frost date is exactly that: an average. It varies from year to year, depending on the season, and can swing wildly.

Microclimates also have an effect. Your yard — or a spot in it — may experience frost well after other areas in your neighborhood based on geographical factors such as low spots where cool air pools at night. Likewise, a particularly sheltered spot may stop seeing frosts several weeks before other areas.
