- First harvests: geraniums
Geraniums (Pelargonium × hortorum) are tender perennials grown as warm-season annuals throughout North America. Prized for their bold flower clusters, long bloom period, and tolerance of summer heat when planted in well-drained soil, they anchor window boxes, containers, and bed borders from late spring until hard frost. Zones 9b–11b can overwinter plants in the ground.
Hood County, Texas is in USDA Zone 8b. The average last spring frost is March 21 and the first fall frost is November 12, giving you a growing season of approximately 236 days.
At an elevation of 1,554 feet, Hood County receives approximately 60.6 inches of rainfall annually with predominantly clay soil. Summer highs average 94°F, providing good warmth for Geraniums during the growing season. Clay soil retains moisture well for Geraniums, but amend with compost to improve drainage and prevent root rot. Ample rainfall means less supplemental watering, but ensure good drainage to prevent Geraniums root diseases.

Geraniums Heat Requirements (GDD)
What are Growing Degree Days (GDD)?
Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.
Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Growing Tips for Geraniums in Hood County
Direct sow Geraniums outdoors after March 21 in Hood County when soil has warmed and frost danger has passed.
With Hood County's clay soil (40% clay), work in 3-4 inches of compost before planting Geraniums. Avoid tilling when soil is wet to prevent compaction.
General growing tips
Start seeds indoors 10–12 weeks before last frost — germination is slow and erratic without bottom heat (70–75°F). Transplant after frost danger passes. Geraniums rarely direct-sown; cuttings or transplants are the standard. Deadhead spent umbels weekly to maintain continuous bloom. Let soil dry slightly between waterings to prevent root rot. In zones 10–11 plants may be left in ground year-round or overwintered as houseplants.
