When to Plant Lobelia in Bee County, TX

In zones 3–7 it delivers a long display; in zones 8–9 it is best treated as a spring annual that fades by midsummer. Trailing types cascade beautifully from containers and window boxes.
Bee County, Texas is in USDA Zone 9b. The average last spring frost is February 13 and the first fall frost is December 11, giving you a growing season of approximately 301 days.
At an elevation of 2,076 feet, Bee County receives approximately 68.3 inches of rainfall annually with predominantly loam soil.

Growing Tips for Bee County
Start seeds indoors 10–12 weeks before last frost — seed is dust-fine and requires light to germinate; surface-sow and press gently. Keep at 65–70°F. Not reliably direct-sown. Transplant in cool weather, 2–4 weeks before last frost date is acceptable in zones 5+. Shear plants by one-third after the first bloom flush to encourage a second flush in fall. Provide afternoon shade in zones 7+ to extend bloom into summer.
