What these dates mean in New Mexico
Harvest usually runs about 173 days, from May 1 to Oct 20.
Frost-date caveat: these are published ranges for New Mexico. A northern or high-elevation site will run later than a southern or low one, and a cold wet spring can push planting past the window. Frost dates and local conditions vary; NASS state-level usual harvest dates (Oct 2010 edition); planting dates not published for alfalfa in most states. Check your last spring frost and soil temperature, and confirm with your county extension office.
