I'm Dreaming of......the Average Date of the Last Spring Frost!

Gardening is dictated by the weather.  The weather tells us when and how to prepare the soil, when to start seeds indoors, or to direct sow in the ground.  It tells us when to protect our plants from in climatic weather and even when to harvest.  We have learned how to "fool" the weather by extending the growing seasons with the use of low and high tunnels or hoop houses, cold frames, frost and shade cloth, and cloches. However, what is probably most important is the average date of the first and last frost.  Of course, this will vary depending on where you live, not only in the country, but also in a region or even by area code.  But, it is this information that will help to create a timeline for your gardening activities.

In the are in which I live (19033), the average date of the last spring frost is April 23.  The average date of the first fall frost is October 15.  However, actual frost dates can vary by 1- 2 weeks.  So it may be possible to plant as early as April 17 and harvest as late as November 1st.  Keep in mind that the average frost date has a 50/50 chance of being correct.  Average does not mean last and there are other factors such as local micro-climates that will play a role in your gardening decisions.

Sweet dreams.........
