In my garden, I aim to plant arugula in both spring and early fall for the best outcomes. The plant favors cooler conditions, so if you can’t start from seeds, consider obtaining young plants from local stores.
If you’re uncertain about harvest readiness, look for leaves growing at least 2-3 inches. Regular picking also encourages further growth and prolongs your harvest period. Pay attention to pest activity, like aphids, and manage them quickly. With the right care, cultivating arugula becomes a fulfilling endeavor that adds a zesty touch to your culinary creations.
Starting Arugula Indoors
In Alaska (Zone 3b), commence indoor arugula seed starting from late April to mid-May. This timing ensures that seedlings are robust and ready for transplantation outdoors around late May to early June, once the frost risk has significantly diminished.
Transplanting Arugula Seedlings
Transplant arugula seedlings outdoors from June 1 to June 15. Make sure the soil temperature has consistently reached above 45°F. Space the seedlings approximately 6-12 inches apart in rows that are at least 12-18 inches apart for optimal growth and air circulation.
General Care and Maintenance
Watering
