17th Annual Persimmon Seed Weather Theory

For seventeen years the Jefferson County Extension office has collected and checked local persimmon seeds to compare winter weather theories with actual weather events for the county. So far the persimmon seeds have been accurate (in theory) thirteen out of seventeen years. This year, for added weather forecasting, we collected persimmon seeds from two different parts of the county - west central and south central - to see if there would be different forecasts. Oddly enough the seeds and fruit from the two areas were different, and the outcome was different with the quantity of predictors in the seeds. Here are the results of this year's annual persimmon seed weather theory for Jefferson County:

Ten seeds were harvested from (each of two different) groups provided to us -

  • Persimmon seeds from the Dittmer area (west central in the county) were dark in color while the fruit pulp was light colored - seeds opened contained 8 "spoons" and 2 "knives"
  • Persimmon seeds from the Valles Mines area (south central in the county) were light in color while the fruit pulp was dark orange - seeds opened contained 6 "spoons" and 4 "knives"

While this comparison isn't largely different, winter weather in both of these areas tend to be different in precipitation and accumulation. According to the seed, this year we will be watching for more wet snow with some frigid temps in the west/central parts of the county, while we will be watching for more cold-cutting wind with a little less accumulation of wet snow in the central to south of the county . . .

Key from The Old Farmer's Almanac: According to folklore, you can predict the weather with a persimmon seed. Here's how to do it: Cut open a persimmon seed. (Find persimmon fruit in your supermarket. It should be locally-grown to reflect your weather.)
Look at the shape of the kernel inside.

  • If the kernel is spoon-shaped, lots of heavy, wet snow will fall. Spoon = shovel!
  • If it is fork-shaped, you can expect powdery, light snow and a mild winter.
  • If the kernel is knife-shaped, expect to be "cut" by icy, cutting winds.

It's best to use ripe seeds.

Plant Diagnostics Clinic Reopens

The University of Missouri Plant Diagnostic Clinic was established in 1965 to provide answers to plant health questions. The clinic takes sample for diagnosis throughout Missouri. They welcome sample submissions to help determine plant health issues and will help track disease or threatening pest locations and noxious weeds. For more information on what can be tested and submission forms and fees check out the MU IPM Program website. You may also bring your samples to the Extension office and we submit the form and plant for you.
