Winter Rye

Question

I was only able to purchase perennial rye grass. I want to use it for a winter cover crop and till it under in the spring. Is this the correct appliction for a green manure versus an annual rye grass.

Answer 1

You need the annual rye grass because the perennial will come back. Even if you till it under any remaining roots will regrow.
