Bristol's improved resistance to downy mildew provides additional harvests before the vines die off. Vigorous plants produce high yields of quality fruits with the classic American cucumber look. Fruits avg. 8" long. Gynoecious. High resistance to anthracnose, angular leaf spot, cucumber mosaic virus, scab, zucchini yellow mosaic virus; and intermediate resistance to downy mildew, powdery mildew, and papaya ringspot virus. NOTES: (1) Not fully immune to downy mildew, Bristol has been shown to survive the disease significantly longer than non-resistant varieties. (2) This variety is gynoecious, which means it will not produce the male flowers required for pollination. Seeds of a pollenizer variety have been mixed into the seed packet at a rate of 10%. As such, it is necessary to plant all seeds in the packet to produce cucumber fruits. Avg. 15,900 seeds/lb. Packet: 30 seeds.
SCIENTIFIC NAME: Cucumis sativus (unless otherwise indicated) CULTURE: Requires warm, well-drained soil high in fertility, with a pH of 6–6.8. Consistent, adequate irrigation is needed to produce an abundant crop. Cucumbers are very sensitive to cold. Make sure both soil and air temperatures have warmed prior to planting. Using plastic mulch and row covers will greatly enhance the vigor and potential yields of cucumbers by providing warmth and insect protection. For greenhouse or high tunnel production the use of gynoecious and parthenocarpic varieties is highly recommended. DAYS TO MATURITY: From direct seeding; subtract about 10 days for days to maturity from transplanting. TRANSPLANTING: Sow indoors in 50-cell plug trays, 1–2 seeds/cell, 3–4 weeks before transplanting. Keep temperature above 70°F (21°C) day and 60°F (16°C) night. Transplant 12" apart in rows 5–6' apart. Do not disturb roots when transplanting. DIRECT SEEDING: Wait until soil is warm, at least 70°F (21°C). Cucumber seeds will not germinate at a soil temperature below 50°F (10°C). Sow 2 seeds/ft., 1/2" deep, in rows 6' apart. Thin to 12" apart. AVG. DIRECT SEEDING RATE: 30 seeds/15', 100 seeds/50', 250 seeds/125', 500 seeds/250', 1,000 seeds/500', 15M/acre at 2 seeds/ft. in rows 6' apart. INSECT PESTS: Exclude cucumber beetles with row covers at planting, or control with insecticides such as pyrethrin or azadirachtin. DISEASE: Practice crop rotation, residue sanitation, and choose disease-resistant varieties. Control insect pests to help prevent bacterial wilt. HARVEST: Once fruit bearing begins, pick daily. POST HARVEST: Hold cucumbers at 45–50°F (7–10°C) and 90% relative humidity for up to 2 weeks. NOTE: If seedless cucumbers cross-pollinate with other cucumbers, they will yield seeded fruits. Generally, seedless types are grown separately in greenhouses or hoophouses with insect screens installed to prevent cross-pollination of seeded and seedless varieties. TRANSPLANTS: Avg. 85 plants/100 seeds. SEED SPECS: SEEDS/LB.: Avg. 20,200. PACKET: 30 seeds, unless otherwise noted.

Days To Maturity
Average number of days from seeding date to harvest, within a specific crop group. If a transplanted crop: average number of days from transplant date. Not sure if crop is direct-seeded or transplanted? Check the Growing Information box for details. If crop can be both direct-seeded or transplanted, days to maturity refers to direct seeding. Days to maturity for all flowers and herbs is calculated from seeding date.
Plants can be Annuals (single growing season), Perennials (grow year after year), Tender Perennials (grow year after year in warmer climates; and in some cases when given special protection in colder climates), or Biennials (require two years to mature).
Disease Resistance Codes
Angular Leaf Spot
Cucumber Mosaic Virus
Zucchini Yellow Mosaic Virus
Papaya Ringspot Virus
Hybrid: The offspring of a cross between two or more distinct parent lines, usually of same species, and selected for improved traits. Open-pollinated: A non-hybrid variety that can reproduce itself in kind, demonstrating relatively stable traits from one generation to the next.
