General Care and Maintenance

Watering

  • Consistently water arugula to keep the soil evenly moist, especially in hot conditions.
  • Water at the base to keep leaves dry, minimizing disease risks.

Fertilizing

  • Apply balanced fertilizer when planting and again when first true leaves emerge. Compost can improve soil quality.

Pest and Disease Management

  • Regular monitoring for common pests is crucial. Managing pests proactively is essential, especially during warmer months.
  • Utilize organic pest management strategies to keep plants healthy.

Harvesting

  • Harvest arugula leaves at 3-6 inches in length. Frequent harvesting promotes new growth.

In my experience, planting arugula in both the spring and fall yields the best results, as it thrives in cooler temperatures. Young plants can also be sourced from local nurseries if seed starting isn’t feasible.

Look for mature leaves of at least 2-3 inches to determine harvest readiness. Regular harvesting can extend the growing season and improve overall yield.

Be vigilant for pests such as aphids to manage them effectively. With the right care, growing arugula can truly enhance your culinary creations.

Starting Arugula Indoors

In Louisiana (Zone 8b), begin indoor arugula seed starting between September 1 and October 15. This timeline ensures healthy seedlings ready for outdoor transplantation starting from late October to early November when the temperatures are cooler.

Transplant arugula seedlings outdoors from late October to early November, ensuring the soil temperature is suitable for growth. Space the seedlings 6–12 inches apart in rows with at least 18–24 inches between rows for optimal growth.

General Care and Maintenance

Watering

  • Provide consistent watering to keep the soil consistently moist, especially during dry spells.
  • Avoid overhead watering to reduce the risk of leaf diseases; water at the base of plants instead.

Fertilizing

  • Apply a balanced fertilizer during planting and side-dress with compost to boost soil fertility as the plants grow.

Pest and Disease Management

  • Monitor for common pests like aphids and flea beetles, as well as diseases such as downy mildew.
