General Care and Maintenance
Watering
- Water arugula consistently to keep the soil evenly moist, particularly important in drier conditions.
- Water at the base of the plants to minimize leaf wetness, which reduces the risk of fungal diseases.
Fertilizing

Pest and Disease Management
- Keeps an eye out for common pests like aphids and flea beetles. Proactive pest management is crucial, especially in warmer weather.
- Utilize organic or integrated pest management strategies to protect arugula from threats.
Harvesting
- Harvest leaves when they reach the desired size, typically 3-6 inches long. Frequent harvesting encourages new growth and prolongs the harvest season.
In my garden, I try to plant arugula in both spring and fall for the best yields, as it thrives in cooler temperatures. If starting from seeds doesn’t fit your schedule, young plants are often available at local nurseries.
When monitoring for maturity, look for leaves that are at least 2-3 inches long. Regularly picking leaves can also promote new growth and extend the harvest.
Remember to check for pests like aphids and manage them promptly. With proper care and attention, growing arugula can be a rewarding experience that adds a delicious touch to your meals.
Starting Arugula Indoors
