How to Grow Cucumbers

Trellis vining cucumbers and keep water steady. Sprawling vines will take a whole bed; vertical plants stay pickable and get more air.

Soil requirements

  • Wait for warm soil before sowing. Cold soil rots seed.
  • Compost-rich raised-bed mix is enough for a start; side-dress if vines pale midseason.

Watering

  • Do not let beds dry to dust, then flood. That is how you get misshapen fruit.
  • Water at the soil line. Wet leaves plus crowding invites mildew.

Sunlight

Full sun. Put the trellis where it will not shade the entire bed all day.

Planting

  • Direct-sow after frost, or transplant with care — cucumbers resent root disturbance.
  • Install the trellis at planting.

Spacing

  • Vining on a trellis: about 12 inches.
  • Bush types: 18–24 inches.

Common problems

  • Powdery mildew

    White film on leaves in late summer. Airflow and resistant varieties help.

  • Cucumber beetles

    Can spread bacterial wilt. Row cover until flowering where beetles are severe.
