When to Plant Daffodils in Rhea County, TN
Daffodils (Narcissus spp.) are among the most dependable and longest-lived of all spring bulbs. Their cheerful yellow and white blooms emerge in early spring, often while frost is still possible, bringing color weeks before most other flowers. Unlike tulips, established clumps naturalize readily — spreading and returning reliably year after year without replanting. Deer and rodents avoid them due to toxic alkaloids in the bulb and sap, making them a low-maintenance choice for naturalized areas, woodland edges, and mixed borders.
Rhea County, Tennessee is in USDA Zone 7b. The average last spring frost is April 13 and the first fall frost is October 22, giving you a growing season of approximately 192 days.
At an elevation of 3,363 feet, Rhea County receives approximately 50.8 inches of rainfall annually with predominantly silt loam soil. Summer highs average 92°F, providing good warmth for Daffodils during the growing season. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Daffodils root diseases.

Growing Tips for Rhea County
Plant bulbs pointed-end up in fall, 6–8 inches deep and 6–8 inches apart in well-drained soil. Allow 12–16 weeks of cold dormancy for proper vernalization. Do not cut back foliage until it turns yellow (6–8 weeks after bloom) — the dying leaves photosynthesize energy into the bulb for next year. Lift and divide overcrowded clumps every 4–5 years in summer after foliage dies back. In zones 7b–9b, select heat-tolerant cultivars (Jonquilla, Tazetta, and Cyclamineus divisions) that perform better with less chill than large-cupped types. Zones 10+: insufficient winter cold; pre-chilling is required but results inconsistent — not recommended for outdoor culture.
