When to Plant Dahlias in Lipscomb County, TX

Dahlias (Dahlia spp.) are the undisputed stars of the late-summer and fall garden, producing an extraordinary range of flower forms — from compact pompons to dinner plate-sized blooms spanning 12 inches — in virtually every color except true blue. Blooming from midsummer until the first hard frost, a single tuber grows into a massive, flower-laden plant that can produce dozens of cut flowers per week. Modern breeding has expanded the palette and forms dramatically; the American Dahlia Society recognizes over 20 flower forms. Extremely rewarding for gardeners willing to invest in the planting, staking, and (in cold zones) annual lifting of tubers.

Lipscomb County, Texas is in USDA Zone 7a. The average last spring frost is April 17 and the first fall frost is October 19, giving you a growing season of approximately 185 days.

At an elevation of 4,634 feet, Lipscomb County receives approximately 48.7 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 94°F, providing good warmth for Dahlias during the growing season. Sandy soil warms quickly in spring — great for early planting — but Dahlias will need more frequent watering and organic matter to retain nutrients.

Growing Tips for Lipscomb County

Plant tubers after all danger of frost has passed and soil temperature reaches 60°F — typically 1–2 weeks after last frost in most zones. Lay tubers horizontally 4–6 inches deep with the eye (growth point) facing up. Do not water until sprouts emerge; wet soil rots dormant tubers. Stake tall varieties (over 3 feet) at planting time to avoid root disturbance later. Pinch growing tips at 12–16 inches to encourage branching and more blooms. Deadhead regularly to extend the blooming season. In zones 8b and warmer, tubers can overwinter in the ground with a layer of mulch. In zones 3–8a, lift tubers after the first killing frost, cure for a week, and store in slightly damp vermiculite or peat at 40–50°F until spring. Divide tubers every year or two; each division must have an eye (bud) to grow.
