Hello,
There is a PlanTalk sponsored by the Colorado State extension on this topic: https://planttalk.colostate.edu/topics/soils-amendments-composting/1607-cover-crops-winter-rye/ that states by spring the Winter Rye will be six to 12 inches high. Before planting in the spring, mow rye grass to chop tops into smaller pieces, and then cultivate to turn it under. The plant residues break down quickly adding needed organic material to improve soil structure and drainage, and improve the soil’s ability to hold nutrients.A rule of thumb is to plan for at least a month in spring after turning under cover crops to allow them to decompose before planting vegetables.
