Caring for Your Indoor Arugula

Keep your arugula thriving with these tips:

• Lighting: Rotate containers for even growth or use grow lights for 14–16 hours daily.
• Thinning: Leave 2–3 inches of space between seedlings for healthy development.
• Watering: Keep soil consistently moist but avoid overwatering.
• Humidity: Maintain moderate humidity to prevent leaf drying.
• Fertilizing: Feed lightly every 2–3 weeks if growth slows.

Troubleshooting Common Issues

• Leggy Seedlings: Provide brighter light or extend daily exposure.
• Yellow Leaves: Check for overwatering or nutrient deficiencies.
• Pests: Address aphids or mites with neem oil or insecticidal soap.
• Fungal Problems: Improve airflow and let the soil dry slightly between waterings.

Harvesting Your Arugula

Harvest arugula in 3–4 weeks for baby greens or 5–6 weeks for mature leaves. Use scissors to snip outer leaves, leaving the inner ones to grow. This “cut-and-come-again” method ensures a continuous harvest.
