Planting season infoApril 5th, 2013 at 9:04 am by Nicholas Ferreri under Weather
It’s been nice to have some spring sunshine and some warmer days in the mix this past week. I know many of you are ready to get out to start work planting your flower beds and gardens. But, of course, for many plants it’s simply too risky to plant them this early in the season. Based on my conversations with viewers around town, I felt now would be a good time to post this info about the typical “safe” dates to plant certain garden items.
Here in northeast Indiana, we fall in Area D (as noted in the map above) which shows our average frost free date ranging from May 6-May 15. Southern and southwestern areas (like Wabash, Marion and Hartford City) fall in Area C, which has an average frost free date in the range of April 26-May 5.
The Purdue Extension Service describes the frost free date in this way: “After the average frost free date, a temperature of 32° is likely to occur 50% of the time, or 1 out of 2 years. About 2 weeks later in the spring, the
chance of 32° decreases to 10%, or 1 in 10. Thus, tender plants set out on the average frost free date will need some protection against cold 1 out of 2 years, while delayed plantings will almost never require additional protection.”
