Starting Indoors

In cities across Maine, begin seeds indoors between April 15 and May 15. This timeline ensures healthy seedlings ready for outdoor transplantation starting from late May to early June once the risk of frost has passed.

Transplanting Seedlings

Transplant seedlings outdoors from June 1 to June 15, ensuring the soil has warmed above 60°F consistently. Space the seedlings 12-24 inches apart in rows with at least 36 inches between rows for optimal growth.

General Care and Maintenance

Watering

  • Provide consistent and deep watering to maintain evenly moist soil. Maine’s varying climate requires regular watering to prevent soil dryness, especially during dry spells.
  • Water at the base of plants to avoid leaf wetness, reducing the risk of fungal diseases.

Fertilizing

  • Apply a balanced fertilizer during planting and when the first fruits start forming. Incorporating compost before planting can enhance soil fertility and structure.

Pest and Disease Management

  • Regularly monitor for common pests like aphids, cucumber beetles, and powdery mildew. While Maine’s cooler temperatures can reduce some pest issues, vigilance is still essential.
  • Implement organic or integrated pest management methods to protect cucumber plants from pests and diseases.

Harvesting

  • Harvest cucumbers when they reach the desired size and color. Regular harvesting promotes continuous fruiting and prevents over-mature fruits.
