Sow shallowly, covering lightly with soil. For continuous harvest, succession plant every 2-3 weeks.

Watering. Maintain consistent moisture, especially during germination and leaf development. Drought stress can lead to bolting and bitterness.

Feeding

Seedlings
Light liquid organic fertilizer, if indoor started.
Growing
Balanced nitrogen-rich fertilizer or compost tea every 2-4 weeks after true leaves appear, particularly for cut-and-come-again harvesting.
Flowering and fruiting
Reduced feeding; focus on vegetative growth for leaf production.
How often
Every 2-4 weeks
Note
Arugula is a light feeder; excessive nitrogen can promote rapid but weaker growth. Prioritize soil health with compost.
