Quick Answer
Direct sow cucumbers in Richmond after April 25 when soil reaches 60°F. Start seeds indoors March 25-April 1 for earliest harvest.
TL;DR
Direct sow cucumbers in Richmond from late April through July once soil reaches 60°F (16°C). Start seeds indoors March 25-April 1 for transplants after the April 15 last frost. Cucumis sativus 'Marketmore 76' is essential for Richmond's Downy Mildew pressure. The 193-day growing season (April 15 – October 25) supports 3-4 succession plantings, and an August fall crop produces excellent quality as Virginia's temperatures moderate.
Frequently Asked Questions
When is the best time to plant cucumbers in Richmond?
Direct sow from late April through mid-July once soil reaches 60°F (16°C) at 4 inches deep. Start seeds indoors March 25-April 1 and transplant after the April 15 last frost. Succession plant every three weeks through mid-July for continuous harvest from late May through October. An August fall planting produces the best-quality fruit of the year. Richmond's 193-day season supports 3-4 successions and a dedicated fall crop that benefits from reduced disease pressure.
What is the best cucumber variety for Richmond?
Cucumis sativus 'Marketmore 76' is the clear best choice after forty years of testing varieties in central Virginia conditions. Its disease resistance provides 3-4 weeks more productive life than susceptible varieties in our humidity. The stay-green gene prevents yellowing during heat waves. For pickling, Cucumis sativus 'Boston Pickling' planted in August produces outstanding fall pickles. Cucumis sativus 'Persian' types work well for containers. Avoid depending on Cucumis sativus 'Straight Eight' past June.
How do I prevent downy mildew on cucumbers in Richmond?
Plant Cucumis sativus 'Marketmore 76' for its intermediate Downy Mildew resistance—this is the single most effective step. Trellis all cucumbers vertically for air circulation. Use drip irrigation exclusively to keep foliage dry. Remove infected leaves immediately when angular yellow spots appear. Succession plant every three weeks so fresh vines replace declining ones. Accept that spring plantings will eventually decline to disease and have the next planting ready to take over production.
Should I plant a fall cucumber crop in Richmond?
The fall crop is often the best harvest of the year. Cooler September and October temperatures reduce Downy Mildew pressure, restore reliable pollination, and produce crisper, better-flavored fruit than the heat-stressed summer harvest. Cucumis sativus 'Boston Pickling' and Cucumis sativus 'Marketmore 76' planted in early August mature into Virginia's mild autumn for four to six weeks of premium production. Row covers extend the harvest 2-3 weeks past the October 25 frost.
How many succession plantings work in Richmond?
Richmond's 193-day growing season supports 3-4 succession plantings spaced three weeks apart. A practical schedule: first transplant late April, second sowing mid-May, third early June, and a fall crop in early August. Each planting produces for 4-8 weeks before declining to disease. This staggered approach maintains continuous harvest from late May through October and ensures you always have healthy, productive vines even as older plantings fade to Downy Mildew pressure.
Do I need raised beds for cucumbers in Richmond?
Raised beds aren't strictly necessary if your Richmond soil drains well—some areas near the James River have decent sandy loam that works fine with compost amendment. On heavier Piedmont clay in western suburbs, raised beds make a significant difference in drainage and root health. Either way, amend with 4-6 inches of compost, mulch 3 inches deep, and trellis vertically. The core practices for successful cucumber growing in Virginia humidity work whether you're in raised beds or in-ground plots. Good drainage, dry foliage, and resistant varieties are the three pillars regardless of garden setup.

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."
