Soil & Bed Preparation

Amend beds with compost and a handful of slow-release organic fertilizer. Cucumbers like warm, loose soil, so form raised rows or mounds for improved drainage.

Watering & Feeding

Ensure cucumbers receive 1 to 1.5 inches of water weekly. Deep morning irrigations help prevent bitter fruit and reduce disease pressure.

Side-dress with compost tea when vines begin to run and again after the first heavy harvest. Foliar feed with kelp for trace minerals if leaves pale.

Training & Maintenance

Train vining varieties on trellises to improve airflow and produce straighter fruit. Pinch tips of lateral shoots after the fifth leaf to encourage branching.

Harvest & Storage

Harvest slicing cucumbers at 6 to 8 inches and pickling types at 3 to 4 inches. Refrigerate in a perforated bag for up to a week or brine within 24 hours for crisp pickles.

Planting Instructions

  • Direct sow after soil warms to 70°F
  • Plant in hills or rows
  • Space 36-60 inches apart for vines
  • Can start indoors 3 weeks early

Care Instructions

  • Provide consistent water
  • Mulch to retain moisture
  • Harvest frequently when small
  • Trellis vining varieties

Seasonal Growing Calendar

Late spring

  • Direct sow when soil reaches 70 F or start transplants in peat pots 3 weeks prior.
  • Cover young plants with row cover to protect from cucumber beetles.
  • Install trellises or cattle panels before vines take off.

Summer

  • Remove row cover at flowering for pollination.
  • Mulch with straw to keep soil cool and suppress weeds.
  • Harvest every two days to prevent oversized, seedy fruit.

Late summer

  • Plant a final succession 60 days before frost for a fall flush.
  • Sanitize trellises and remove diseased foliage promptly.
  • Sow a cover crop after vines decline to restore soil.
