When to Plant Begonias in Jeff Davis County, TX

Wax begonias (Begonia × semperflorens) are the workhorse shade bedding plant of American horticulture, offering continuous bloom from transplant to hard frost. Bronze or green-leaved varieties perform well from deep shade to full sun (in northern zones) and tolerate summer humidity better than most cool- season flowers. A staple of mass plantings, containers, and window boxes.

Jeff Davis County, Texas is in USDA Zone 8a. The average last spring frost is April 3 and the first fall frost is November 1, giving you a growing season of approximately 212 days.

At an elevation of 4,298 feet, Jeff Davis County receives approximately 52.4 inches of rainfall annually with predominantly sandy loam soil. Summer highs average 96°F, so Begonias may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Begonias will need more frequent watering and organic matter to retain nutrients. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Begonias root diseases.

Growing Tips for Jeff Davis County

Start seeds indoors 10–12 weeks before last frost — seed is dust-fine; surface-sow on moist mix under lights, do not cover. Bottom heat (70–75°F) speeds germination. Transplant after frost; begonias are not direct-sown in practice. Pinch seedlings once for branching. Keep soil evenly moist; avoid waterlogged conditions. Bronze-leaf types tolerate more sun; green- leaf types prefer shade to part-sun.
