When to Plant Crocus in Sherman County, TX

Crocuses (Crocus spp.) are the heralds of spring — small, gem-like blooms that push up through frozen ground or even snow, often weeks before any other flower. Their compact corms naturalize readily in lawns, rock gardens, and borders, creating drifts of purple, white, and yellow that expand year after year. Bees prize early crocus as one of their first nectar and pollen sources of the season. The saffron crocus (C. sativus) blooms in fall and yields the world's most expensive spice.

Sherman County, Texas is in USDA Zone 7a. The average last spring frost is April 20 and the first fall frost is October 18, giving you a growing season of approximately 181 days.

At an elevation of 3,372 feet, Sherman County receives approximately 46.5 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 91°F, providing good warmth for Crocus during the growing season. Sandy soil warms quickly in spring — great for early planting — but Crocus will need more frequent watering and organic matter to retain nutrients.

Growing Tips for Sherman County

Plant corms 3–4 inches deep and 2–3 inches apart in fall, when soil temperature drops below 60°F. Mass plantings (at least 25 corms per cluster) create the most visual impact. Plant in well-drained soil — corms rot in standing water. Crocus naturalize well under deciduous trees; the tree leafs out after crocus dormancy begins, so light competition is minimal. Squirrels and chipmunks dig corms — plant deeper (4 inches) or use wire mesh baskets in high-predation areas. Allow foliage to die back naturally before mowing lawns. In zones 8a–8b, plant in December with pre-chilled corms for best results.
