Quick Answer
Direct sow lettuce outdoors March 10-25 in Richmond. Seeds germinate in soil as cool as 40°F. Fall sowing August 10-25 for the best harvest of the year.
TL;DR
Direct sow lettuce outdoors March 10-25 or start seeds indoors February 20-March 5 for the spring window. Richmond's 193-day frost-free season and Zone 7b climate at the Piedmont-Tidewater transition create a summer gap of 8-10 weeks (mid-June through mid-August) with excellent spring (March-June) and fall (September-November) windows. Lactuca sativa 'Buttercrunch' leads for bolt resistance. Richmond's deep gardening heritage—Virginia has grown lettuce since the colonial era—and the city's moderate humidity make it one of the most productive mid-Atlantic lettuce cities.
Frequently Asked Questions
When is the best time to plant lettuce in Richmond?
Direct sow lettuce outdoors March 10-25—it germinates in soil as cool as 40°F. Succession sow every 10-14 days through mid-May for continuous spring harvest. For the fall window, start seeds indoors August 10-25 to bypass thermoinhibition, then transplant outdoors by early September. Fall lettuce from September through November produces the year's best quality with frost-sweetened leaves. Richmond's 193-day season supports 7-9 total succession plantings across both windows with Zone 7b winters enabling limited winter production.
What is the best lettuce variety for Richmond?
Lactuca sativa 'Buttercrunch' is the best all-around choice because its bolt resistance extends the spring window 2-3 weeks before Virginia's humid summer arrives. Lactuca sativa var. crispa (Red Oak Leaf) at 45-55 days provides fast cut-and-come-again harvesting with vivid fall coloration. Mesclun mix delivers the fastest harvest at 30-40 days. Lactuca sativa var. longifolia (Romaine) excels as a fall crop with frost tolerance to 20°F extending harvest into December and overwintering potential under cold frames in Zone 7b.
What makes Richmond's soil situation unique?
Richmond straddles the fall line where Virginia's Piedmont meets the Tidewater coastal plain, creating two distinct soil types within the metro area. Western neighborhoods sit on heavy, acidic Piedmont clay (pH 5.5-6.5) that needs compost for drainage and possibly lime for pH correction. Eastern neighborhoods have sandier coastal plain soil that drains well but needs compost for moisture and nutrient retention. Test soil through Virginia Cooperative Extension before planting. Raised beds with controlled soil mix bypass both challenges entirely.
How long is Richmond's summer lettuce gap?
Richmond's gap runs approximately 8-10 weeks from mid-June through mid-August when temperatures exceed 85°F with 65-75% humidity. This is comparable to the Carolinas and shorter than deeper South cities like Atlanta (10-12 weeks) and Dallas (12-14 weeks). With shade cloth and bolt-resistant Lactuca sativa 'Buttercrunch', production extends into late June. The gap is manageable with a two-season approach that maximizes the excellent fall window.
Can I grow lettuce through Richmond's winter?
Limited winter production is feasible in Zone 7b with row covers or cold frames. Richmond's mild winters (average lows 28-33°F) support cold-hardy varieties like Lactuca sativa var. longifolia (Romaine) with frost tolerance to 20°F. Romaine can overwinter under cold frames in Zone 7b, resuming active growth in late February. Growth slows significantly in December-January but doesn't stop entirely in protected beds—Virginia's Zone 7b winters are mild enough for lettuce survival with basic season extension infrastructure like row covers and cold frames.
How does Richmond connect to Virginia's lettuce heritage?
Thomas Jefferson grew over 15 lettuce varieties at Monticello just 70 miles west of Richmond, practicing the succession planting methods that modern guides still recommend. Virginia's long agricultural tradition established lettuce as one of the Commonwealth's cool-season garden staples centuries before modern gardening culture emerged. Richmond's Lewis Ginter Botanical Garden, Virginia Cooperative Extension, and active farmers market network sustain this heritage and provide the region-specific expertise that benefits lettuce growers across central Virginia.

After retiring from teaching elementary school, she became a Master Gardener volunteer and spends her time mentoring new gardeners at community garden plots in Richmond. She's especially knowledgeable about heirloom varieties, seed saving, and traditional growing methods passed down from her grandmother. Dot's no-nonsense advice comes from extensive trial and error—she's seen every tomato disease, pest problem, and weather disaster imaginable. Her biggest pet peeve is gardeners who overcomplicate simple tasks. "Plants want to grow," she often says. "Your job is to not get in their way."
