Alfalfa winter kill

[BuckNasty83]

I planted some 505 alfalfa about 3 weeks ago.... Late, I know, but lack of rain forced me to plant a couple weeks later than intended. The plants are only a couple of inches tall right now. I'm wondering if this cold weather coming will kill them off before they truly get established? They have a LIGHT nurse crop of oats mixed in.

The 505 has a fall dormancy rating of 5 , but is mid to low 30s too much for a 3 week old?

I’m not sure. Please update and let us know. Good luck.

Probably be fine.It takes some long below freezing temps dropping the soil temp to freeze off oats.

It has to be below 24f to damage it
