Relative green-up dates for different grass and legume species

Asked December 3, 2018, 8:45 PM EST


I'm looking for spring green-up dates for pasture grasses and legumes. I realize that exact location makes a big difference in date; I'm more interested in relative dates, "a month after species A" or "once soil temperature reaches 40 degrees" etc.

Do you know if there are resources online that deal with this?

Your question was assigned to a Colorado Master Gardener of which small acreage management, pasture grasses and legume foraging is not really our area of expertise.

Provided are links to the Small Acreage Management section of Extension that might be of assistance, and also the contact email for this specialized area:

Below is the CSU Turf website with resources on grasses. Dr. Koski, a turf specialist, would also be able to answer questions on pasture mixes that likely include grasses such as orchardgrass, brome, fescue, rye, etc.
