Can I winterize over snow ?

[skippynj17]

I was just wondering If I can drop my winterizer (46-0-0 urea) . where I live we received about 3-4" of snow yesterday. I never got to put the winterizer down because up until last week my lawn was still growing about 1/8 inch per week.
The forecast for the next few days looks like temps in the low 40s with 100% chance of rain tuesday morning. Should I fertilize or did I miss the boat ? Thanks

I don't know how easy it will be to push the spreader in snow, but if you can do it I guess you'll see the tracks of the spreader easily though. Personally Im not sure if the urea will be affected by the snow. Someone else will have to answer that aspect. My own concern would be lawn damage if it's below 38 degrees and/or icy.

What is special about 38 degrees?

Oh, thats the average high temp at which frost often forms or is still on the ground in my area. I assume it's the same in most. I actually remember hearing a weather say it once, confirming my own observations.

That's nonsense. Frost can only form at 32 degrees or below. Now, the temperature 6' or 10' up might be higher. Frost is ice, and ice requires 32 degrees or less. Yes, even "in your area". Your area, my area, Kansas and China too.

Andy...it's not nonsense. I'm not a weather expert, so I can't explain the exact factors...but I have had frost when the official current air temp, reported by the weather, is 38. I don't know if that's due to a temperature difference between the location of the weather station and where I am, or if it's due to lingering frost in the morning that still hasn't melted, or something else. We've also gotten snow at above the freezing mark as well. Not to mention the lingering snow takes time to melt...I'm sure you have those big piles that melt slowly over time...so that may be the explanation. Regardless of the reason, I've had frost at temps as high as 38. No laws of physics were broken.

That’s exactly what it is. The tempersture at your weather station can vary from where you see the frost depending on a range of factors.

Andy is correct, Frost only happens at 32 degrees F.

Your not going to damage your lawn by walking on the snow.

Standard temperature measurements for your local station (and for my backyard station, for that matter!) are taken four to six feet off the ground (about five for me).

The temperature at that height, on a still night, can be degrees above the temperature at the grass layer due to cold air falling. So frost can absolutely form at an official temperature of 38 in your area (usually more like 36 for me here). It's just that the temperature at the grass layer is 32 or below.

Morph...that's probably the most typical explanation for what I've seen over and over again.

If you do this please be sure to get some video and make sure the neighbors standing in their windows shaking their heads are in the shot. Thanks in advance.
