Wildsky
Garden Ornament
Hi Steve,digitS' said:I'm becoming more and more of a believer in soil temperature as a guide for early planting, Wildsky. The air temperature will have only a little effect on seed planted 1 or 2 inches into the soil and plants can't read a calendar.
You can look at that linked chart from the University of Minnesota and see that it would serve no purpose to plant bean seed when the soil temperature is only 41F - that NG stands for "no germination." In fact, they won't germinate at 50F but somewhere above that temperature, the seeds will start to grow after awhile. (Look how early that you can get your lettuce and spinach seed out there, however
Steve
Thanks for that chart, what are the numbers on it? (the number of plants that germinated in the test?)
Is there a way to take the soil temp? Perhaps I'll have area's that are warmer than others. I did want to plant my vegies in my back yard.... but thats between the garage on the west side and the house on the south.... takes the snow longer to melt in that area, so probably stays cold longer....
