Starting Cucumbers Indoors

In Massachusetts, particularly in cities like Boston (Zone 6a), start indoor cucumber seed sowing between April 15 and May 15. This timing allows for robust seedlings ready for outdoor planting around late May to early June after the danger of frost has passed.

Transplanting Cucumber Seedlings

Transplant your cucumber seedlings outdoors from June 1 to June 15, ensuring that the soil temperature remains consistently above 60°F. Space the seedlings approximately 12-24 inches apart in rows with a minimum of 36 inches between rows to facilitate healthy growth.

General Care and Maintenance

Watering

  • Provide regular and thorough watering to ensure the soil stays consistently moist. Massachusetts’ varying climate may require additional watering during dry spells.
  • Water at the plant base to prevent leaf wetness and minimize the chances of fungal infections.

Fertilizing

  • Utilize a balanced fertilizer when transplanting and once the cucumber plants begin fruiting. Adding compost before planting can enrich the soil quality and composition.

Pest and Disease Management

  • Regularly inspect for common pests such as aphids, cucumber beetles, and powdery mildew. Vigilance is key in managing pests despite Massachusetts’ moderate humidity levels.
  • Employ organic or integrated pest management strategies to safeguard cucumber plants from potential threats.

Harvesting

  • Harvest your cucumbers once they reach the desired size and color. Consistent harvesting encourages continuous fruit production and prevents the cucumbers from becoming overly ripe.
