Arugula requires consistent moisture to prevent bolting and maintain tender leaves. Water regularly, especially during dry spells, aiming for about 2.5 cm of water per week, either from rain or irrigation. Ensure the soil remains evenly moist but not waterlogged, as excessive wetness can lead to root rot. Reduce watering slightly as temperatures cool.

Pruning for arugula primarily involves harvesting the outer leaves as needed, which encourages continuous production. Pinch off flower stalks (bolting) as they appear to prolong the harvest of tender leaves, as flowering can make leaves bitter. Remove any yellowing or damaged leaves to maintain plant health and vigor.

Arugula is easily propagated from seed. Sow seeds directly into the garden bed or containers in early spring or late summer. Plant seeds about 0.5-1 cm deep and 2.5 cm apart, thinning seedlings to 10-15 cm apart once they are a few centimeters tall. Germination typically occurs within 5-10 days.

Arugula is an annual plant typically grown from seed directly in its final location, whether in the ground or a container. Repotting is generally not necessary or recommended. If starting seeds indoors, transplant seedlings carefully into larger pots or the garden bed once they have developed a few true leaves and the risk of frost has passed.
