Learn how to grow organic arugula from seed to harvest in raised beds or containers. This step-by-step guide covers planting, care, and harvesting for beginners.
Quick answer
To grow organic arugula successfully, sow seeds directly in well-drained soil in early spring or fall, keep the soil moist, and harvest leaves when they are 3-4 inches long for the best flavor.
Why grow arugula in raised beds?
Raised beds warm up faster in spring, allowing you to sow arugula seeds earlier. They also provide better drainage, which prevents root rot and keeps the soil loose for easy harvesting. If you don't have a raised bed, a deep container works well too.
When to plant arugula
Arugula thrives in cool weather. Plant seeds as soon as the soil can be worked in spring, or 4-6 weeks before the first fall frost. In mild climates, you can grow it through winter with a simple row cover. Avoid midsummer heat, which makes the leaves bitter.
Step-by-step growing guide
- Prepare the soil: Loosen the soil to at least 6 inches deep and mix in a 1-inch layer of compost. Arugula prefers a neutral pH (6.0-7.0). Avoid fresh manure; it can burn tender seedlings.
- Sow the seeds: Scatter seeds thinly about 1/4 inch deep and cover lightly with soil. Space rows 6 inches apart. Water gently with a fine spray. Overcrowding leads to weak plants; thin seedlings to 4 inches apart after they sprout.
- Water consistently: Keep the soil evenly moist, especially during germination (5-7 days). Once established, water 1 inch per week. Inconsistent watering causes bitter, tough leaves.
- Harvest leaves: Pick outer leaves when they are 3-4 inches long, leaving the center to continue growing. You can also cut the whole plant 1 inch above the soil for a cut-and-come-again harvest. Harvest in the morning for the crispest leaves; older leaves become spicy and tough.
