Introduced in 1968 by Cornell University, 'Marketmore' is a beautiful, dark green cucumber that's ready to pick when 6"–8" long. Fruits keep their size and shape even under poor weather conditions unlike other varieties that may curl and become misshapen. The 4'–6' long vines continue to produce with regular picking. Disease resistant.

• Type: Monoecious, slicing cucumber
• When to Sow Outside: RECOMMENDED. 1 to 2 weeks after your average last frost date, and when soil temperature is at least 60°F, ideally 70°–90°F.
• When to Start Inside: 2 to 4 weeks before your average last frost date. Cucumbers are sensitive to root disturbance; sow in biodegradable pots.
• Days to Emerge: 5–10 days
• Seed Depth: ½"
• Seed Spacing: A group of 2 seeds every 12"
• Row Spacing: 36"
• Thinning: When 3 leaves, thin to 1 plant every 12"
• Harvesting: Pick, and pick some more! Overly mature cucumbers on the vine will slow production of new cucumbers. Cut the stem rather than pulling at the fruit, as stems are fragile. To increase the quality and storage time, once picked, immediately immerse in cold water to disperse "field heat".
