Mora County, New Mexico is in USDA Zone 6a. The average last spring frost is May 22 and the first fall frost is September 25, giving you a growing season of approximately 126 days.

Growing Tips for Mora County

Direct-sow in early spring as soon as soil can be worked; seeds need a brief cold period for best germination (refrigerate for a few days before planting if spring arrives quickly). In zones 6+, fall-sow for the earliest spring bloom. Thin to 12 inches; do not over-fertilize — too much nitrogen produces foliage at the expense of flowers. Deadhead to prolong blooming or allow self-seeding for a naturalized colony.
