Planting Garden Vegetables Based on Soil Temperature

Not only does frost-free weather initiate the planting of warm season vegetables (like tomatoes), but soil temperatures play a strong role when it comes time to planting both cool season and warm season vegetables. Certainly this spring has been challenging for gardeners waiting to get cool season vegetables planted and now with Mother’s Day just around the corner, chances are good that planting warm season vegetables should be delayed as well. Rather than relying solely on the calendar to determine timing—“I always plant after Mother’s Day”—this year is definitely one that requires greater attention to soil temps and frost forecasts. While seeds and plants of cool season vegetables like radishes  and cabbage will survive if planted too soon, warm season vegetables (like beans and peppers) planted too soon will perish when soil temperatures are too cold for them.
