General Care and Maintenance

Watering

  • Maintain consistent moisture in the soil, especially in dry spells.
  • Watering at the base of plants minimizes leaf wetness and helps prevent fungal issues.

Fertilizing

  • Apply a balanced fertilizer during planting and reapply when true leaves appear. Incorporating compost can also boost soil nutrient levels.

Pest and Disease Management

  • Keep an eye out for common pests like aphids and flea beetles. Regular monitoring is essential.
  • Implement organic or integrated pest management techniques to protect your plants.

Harvesting

  • Harvest leaves at a desirable size of 3-6 inches. Frequent harvesting prompts new growth and extends the harvest period.


In my personal experience, I plant arugula both in spring and again in fall for optimal production. This crop prefers cooler temperatures. If you’re busy, you can often find young plants at local nurseries.

To know when to harvest, look for mature leaves around 2-3 inches long. Picking leaves regularly can spur new growth and prolong your harvest.

Additionally, keep an eye out for pests such as aphids and address any issues immediately. With care and attention, cultivating arugula can be a fulfilling experience that enhances your meals.
