Starting Cucumbers Indoors

In Louisiana, particularly in cities like Baton Rouge (Zone 9a), begin indoor cucumber seed starting around March 1 to April 1. This timing ensures robust seedlings ready for outdoor planting from late April to early May once the last frost has passed.

Transplanting Cucumber Seedlings

Transplant cucumber seedlings outdoors between April 15 and May 1, making sure the soil temperature is consistently above 60°F. Space the seedlings 12-24 inches apart within rows and keep at least 36 inches between rows for optimal growth.

General Care and Maintenance

Watering

  • Provide regular and thorough watering to maintain consistently moist soil. Louisiana’s warm climate may require more frequent watering to prevent drying out.
  • Water at the plant base to avoid wetting the leaves, reducing the likelihood of fungal issues.

Fertilizing

  • Apply a balanced fertilizer during planting and when the first fruits start developing. Adding compost before planting can enrich soil nutrients and structure.

Pest and Disease Management

  • Regularly check for common pests such as aphids, cucumber beetles, and powdery mildew. Louisiana’s humid conditions may favor pest presence.
  • Utilize organic or integrated pest control methods to safeguard cucumber plants from pests and diseases.

Harvesting

  • Harvest cucumbers once they reach the desired size and color. Regular harvesting encourages continuous fruit production and prevents overripe fruits.
