At what soil temperature do most plants begin to grow, for example, grasses, flowers and other plants, is there a certain threshold beyond which most or all plants begin to germinate and grow

there is a difference between plants regarding this .........thus different planting dates.


Even a difference in corn


Field corn 52 degrees
Sweet corn 55 degrees


(soil temp at 2 inch depth for germination )

I started a thread on soil temps but doesn't look like there was interest. lol Thought it would be helpful.


Soil Temperature, Local, Maps, and Links




On your question, I think each plant has its own criteria but I would think soil temp above mid 40s is ideal for the "start" of everything. Also note, its not just about the surface. Pick up an inexpensive thermometer and measure it. Keep track of it. Maybe do it once or twice a week? Get a measurement at 1" down and 4 inches down.




Check this out. Current soil temps are pretty much in the 30s everywhere in Northeast and most of Ohio Valley.


but check out by Sunday. This model from my paid software is showing this as the average soil temp from surface to 4 inches down. Wow at the 50s! It's a tease because cold is coming back and soil temps drop down fast by end of month.

We have been in the 40s the last couple of weeks, high 30s at night. The grass is growing, and I see the mums, Hydrangeas and roses starting to sprout. We have tulips about 4" high. All of those will start at a much lower temperature than the vegetables, which I cannot plant until the soil is in the 50s, about May.
