It’s nearly impossible to predict how much damage this past winter’s weather did to existing alfalfa fields. While alfalfa usually comes through winter in pretty good shape in our area, I’m sure this year there could be plenty of exceptions.
It will be a couple weeks at least before you might expect to see the beginnings of spring growth. However, it’s important that you determine the amount of damage as soon as possible so you have time to respond in the best way possible.
