    Growing notes: Days to maturity are from direct seeding, subtract 10 days if transplanting. Cucumbers are warm season tender annuals that enjoy generous amounts of organic matter and good fertility. They can be direct seeded after all danger of frost has passed or begun as transplants 3-4 weeks before planting date. Optimal soil temperature for germination is 75-85°F. Plastic mulch and row covers are commonly used for field cucumbers to increase temperature and ward off insects. Thin-skinned cucumbers are especially affected by cucumber beetle feeding and may require row cover. Monoecious plants have both male and female flowers and require pollination. Greenhouse cucumbers are parthenocarpic and are able to produce fruit without pollination. Gynoecious plants produce predominately female flowers and require a pollinator partner. Harvest cucumbers regularly to increase production. Cucumbers store well for up to 7-10 days at 50-55°F with 95% relative humidity and can become injured at temperatures lower than 50°F. Thin-skinned cucumbers are best stored wrapped in plastic. Beit Alphas are similar to European/Dutch types with the same ribbed skin but smaller.

  • Adam F151–69 days

    Parthenocarpic; 3-4” fruit

    Resistance: HR: Cucumber Mosaic Virus; Powdery Mildew; Scab · IR: Downy Mildew

    Early, heavy yields of gherkin-type fruit for pickling. Fruit possesses a full, even shape with minimal tapering at a small size. Dense, crisp flesh and characteristic bumpy skin are most pronounced when young and help maintain crispness in pickling. Plants do not require pollination—perfect for greenhouses. Also performs great in the field.

    Growing notes: Days to maturity are from direct seeding, subtract 10 days if transplanting. Cucumbers are warm season tender annuals that enjoy generous amounts of organic matter and good fertility. They can be direct seeded after all danger of frost has passed or begun as transplants 3-4 weeks before planting date. Optimal soil temperature for germination is 75-85°F. Plastic mulch and row covers are commonly used for field cucumbers to increase temperature and ward off insects. Thin-skinned cucumbers are especially affected by cucumber beetle feeding and may require row cover. Monoecious plants have both male and female flowers and require pollination. Greenhouse cucumbers are parthenocarpic and are able to produce fruit without pollination. Gynoecious plants produce predominately female flowers and require a pollinator partner. Harvest cucumbers regularly to increase production. Cucumbers store well for up to 7-10 days at 50-55°F with 95% relative humidity and can become injured at temperatures lower than 50°F. Thin-skinned cucumbers are best stored wrapped in plastic. Beit Alphas are similar to European/Dutch types with the same ribbed skin but smaller.

  • DMR 40157–77 days

    Monoecious; 7” fruit

    Resistance: HR: Downy Mildew

    The leading source of resistance to the new strain of downy mildew in cucumbers. DMR 401 offers resistance to the newest strain of cucurbit downy mildew with foliage that stands strong against the pathogen to keep producing sizable, uniform fruits. The hands-down winner for mildew resistance in both extension and farmer trials. Best used in regions with heavy DM pressure and during seasonal slots when DM is expected. Bred by Dr. Michael Mazourek of Cornell University with the support of a USDA-NIFA-OREI grant. A portion of the sales of this variety is paid to the breeder. Limited availability in 2024

    Growing notes: Days to maturity are from direct seeding, subtract 10 days if transplanting. Cucumbers are warm season tender annuals that enjoy generous amounts of organic matter and good fertility. They can be direct seeded after all danger of frost has passed or begun as transplants 3-4 weeks before planting date. Optimal soil temperature for germination is 75-85°F. Plastic mulch and row covers are commonly used for field cucumbers to increase temperature and ward off insects. Thin-skinned cucumbers are especially affected by cucumber beetle feeding and may require row cover. Monoecious plants have both male and female flowers and require pollination. Greenhouse cucumbers are parthenocarpic and are able to produce fruit without pollination. Gynoecious plants produce predominately female flowers and require a pollinator partner. Harvest cucumbers regularly to increase production. Cucumbers store well for up to 7-10 days at 50-55°F with 95% relative humidity and can become injured at temperatures lower than 50°F. Thin-skinned cucumbers are best stored wrapped in plastic. Beit Alphas are similar to European/Dutch types with the same ribbed skin but smaller.

  • BuckwheatEvidence tier C: Traditional practice with plausible mechanism but limited empirical replicationpollinator-attract, predator-attract

    Buckwheat insectary strips near cucurbits boost hoverfly populations that prey on cucumber aphid; some evidence of reduced cucumber beetle pressure where Syrphid predation suppresses early aphid colonies.

    Timing: Time buckwheat bloom to overlap with cucurbit pest pressure (mid-July).

    Phacelia is exceptional for hoverfly (Syrphidae) and honeybee attraction — among the highest-rated insectary plants in North American and European field trials. Strips adjacent to cucurbits boost pollination and aphid biocontrol. UC IPM and Xerces document.

    Timing: Sow early spring or late summer; flowers 6-8 weeks from sowing.

    Region: Cool-season; bolts in heat above 80°F. NA cucurbit-specific replicated trials are thin; phacelia's value as an insectary plant is broadly accepted but cucumber-specific yield/pest-reduction evidence is limited.

When to feed, prune & water

Attract beneficial insects and protect pollinators

Protection
  • Routine carePlant insectary flowers and tolerate light pestsstrong evidence — extension confidence

    Grow a diversity of flowering plants (including small-flowered umbels and asters) to feed predators and parasitoids, and tolerate low pest numbers so natural enemies have prey to stick around.

    Source: UC IPM; UMN Extension

Symptoms: sudden wilting and collapse of peppers or squash; dark water-soaked lesions at the crown or stem base; white cottony growth on infected fruit; root and crown rot; vine and fruit rot after heavy rain or in wet low spots

  • CulturalRemove affected plants at first sign (manage, not cure)strong evidence — extension confidence

    Infected plants can't be saved; promptly pull and destroy them at the start of an outbreak to slow spread, and avoid working in beds when wet.

    Source: Cornell Vegetables; UMN Extension

  • CulturalImprove drainage and avoid waterloggingstrong evidence — extension confidence

    Plant on raised beds, never let beds stay saturated, and water with drip rather than flooding, since this water mold thrives in standing water and saturated soil.

Symptoms: sudden wilt and crown collapse; soft water-soaked rot at the crown; large tan-to-salmon soft spots on fruit; white yeast-like mold on rotting fruit; plants dying in wet low spots

  • CulturalImprove drainage and avoid waterloggingstrong evidence — extension confidence

    Plant on raised, well-drained beds, avoid low wet spots, and lengthen intervals between irrigations, since this water mold thrives in saturated soil. Once established it is very hard to control, so prevention is key.

    Source: UC IPM; Clemson Extension

  • CulturalRotate and avoid infested fieldsstrong evidence — extension confidence

    Avoid sites with a Phytophthora history and rotate to non-host crops (avoid cucurbits, peppers, tomato, eggplant), since the oospores survive in soil for years.
