How to Grow Aruguletta
Aruguletta
Diplotaxis tenuifolia
vegetableAruguletta is a perennial leafy green closely related to common arugula, featuring smaller, more delicate leaves with a milder, slightly sweet peppery flavor. Native to the Mediterranean region, it's prized by chefs for its tender texture and refined taste. Unlike annual arugula, this variety can regrow multiple harvests over several seasons.

Germination & Seedling
2-3 weeksSeeds sprout within 5-10 days. Tiny cotyledons emerge, followed by the first true leaves with finely dissected edges.
Keep soil moist but not soggy. Provide bright light immediately after sprouting. Thin seedlings to proper spacing once they have 2-3 true leaves.
Vegetative Growth
2-4 weeksPlant develops rosettes of increasingly delicate, deeply lobed leaves. Growth is relatively vigorous and bushy at this stage.
Water consistently. Fertilize lightly with balanced or nitrogen-rich fertilizer every 2-3 weeks. Ensure adequate airflow to prevent fungal issues. Remove any damaged leaves.
Leaf Maturation & First Harvest
1-2 weeksInner leaves reach full size and tenderness (3-4 inches long). Plant has developed a substantial rosette ready for harvesting.
Begin harvesting outer leaves once they reach desired size. Cut leaves at soil level or pinch off individual leaves, leaving the center to continue growing. This stimulates branching and fuller regrowth.
Continuous Harvest & Regrowth
Months (spring through fall, or year-round in mild zones)Plant produces successive flushes of new leaves throughout the season. In mild climates, can produce for months.
Harvest the outer leaves regularly to encourage continued production. Deadhead any flower buds that form to extend the vegetative stage. Continue regular watering and light feeding.
Flowering & End of Season
Variable; allows plant to go to seed or overwinterSmall yellow flowers appear as the plant transitions to reproduction. Leaves may become tougher and more peppery.
If continued leaf production is desired, pinch off flower buds. Allow plants to flower if you want seeds for next season. In perennial zones, cut plant back hard in fall for winter dormancy and spring regrowth.

Harvest Tips
Begin harvesting when leaves are 2-3 inches long, typically 30-45 days after sowing. Use the 'cut and come again' method: harvest outer leaves at the base using a sharp knife or pinch them off by hand, leaving the inner crown intact to continue producing. Early morning harvest yields the crispest, most tender leaves. In hot weather, harvest in early morning or evening to catch cooler temperatures. For perennial management, cut back the entire plant by half every 6-8 weeks to rejuvenate growth and prevent flowering.
