Starting Cucumbers Indoors

In cities like Phoenix, Arizona (Zone 9), begin indoor cucumber seed starting between March 15 and April 15. This timeline ensures healthy seedlings ready for outdoor transplantation starting from late April to early May once the risk of frost has passed.

Transplanting Cucumber Seedlings

Transplant cucumber seedlings outdoors from May 1 to May 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. Arizona’s dry climate necessitates regular watering to prevent soil dryness.
  • 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 Arizona has lower humidity, pest vigilance is 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.
