Soil temp, 3/26

[LwnmwnMan2]

A buddy of mine that does the same work as I do has been doing soil temps in his yard.

Last week they peaked at 51.2 degrees and we were getting quite antsy.

Today he just called to say they have already dropped back down to 46.3 degrees, much more than I had imagined.

I thought MAYBE a degree, not 5.

Here is a link to soil temperature data from the St. Paul campus weather observatory illustrating exactly that under bare soil & sod conditions.

At what point again do we want to get down crab grass preventer?

General rule of thumb is 55 degrees at sunrise for 3 consecutive mornings.

Can you use something like when the lilacs bloom it is time? Dandelions?

Generally when the Lilacs are blooming, not just leafing.

I was getting 55-65 all over my yard yesterday. With the cold rain we got today, I wouldn't doubt it went down 5 or so degrees.
