🥕 Arugula

Eruca vesicaria subsp. sativa

vegetables leafy green (brassicaceae)

☀️ Sun

Full sun in cool weather; partial shade (4–6 hours) in warm weather to delay bolting; afternoon shade extends harvest

💧 Water

Medium; 1 inch per week; consistent moisture produces tender, less-peppery leaves; drought stress makes leaves hotter/more pungent and causes bolting

🗺️ Zones

3, 4, 5, 6, 7, 8, 9, 10

🪴 Soil Type

Rich, well-drained loam with moderate organic matter; arugula grows well in average garden soil — too much nitrogen produces overly pungent leaves

🧪 Soil pH

6.0–7.0 (slightly acidic to neutral)

💧 Drainage

Well-drained; does not tolerate soggy soil — causes root rot and weak plants

📏 Spacing

Seeds 1 inch apart, thin to 4–6 inches; rows 12 inches apart; broadcast sow for baby-leaf production (cut at 3–4 inches)

📅 Days to Maturity

21-40 days (from seed) for baby leaves; 35-50 days for full size

🍴 Edible Parts

🍽️ ["Leaves (raw or cooked)"🍽️ "Flowers (edible \u2014 white with purple veins🍽️ mild peppery flavor)"🍽️ "Seeds (pressed for oil \u2014 taramira oil in India)"🍽️ "Seed pods (young pods edible)"]

🤝 Companions (6)

🤝 Bush bean

Beans fix nitrogen to support arugula's leaf production; beans provide light partial shade delaying bolting in warm weather

🤝 Carrot

Different root depths — arugula is shallow, carrots are deep; arugula germinates quickly, marking rows for slow carrots

🤝 Radish

Both are fast-growing brassicaceae; radishes mark rows and break soil crust; harvested before arugula needs full space

🤝 Nasturtium

Trap crop for flea beetles (the main arugula pest); nasturtiums draw flea beetles away from arugula

🤝 Dill

Attracts beneficial wasps that prey on caterpillars; dill's aromatic compounds may deter flea beetles

🤝 Lettuce

Similar growing conditions; arugula's strong scent may confuse lettuce pests; both cool-season crops

⚠️ Keep Apart (3)

⚠️ Strawberry

Strawberries and arugula compete for space; strawberries may inhibit arugula growth through root competition

⚠️ Fennel

Allelopathic — inhibits most garden plants including arugula

⚠️ Nightshades (tomato/eggplant/pepper)

Some sources report brassicas may stunt nightshade growth through root exudates; separate if possible

💊 Medicinal Uses

["Contains glucosinolates (erucin) \u2014 being studied for anti-cancer properties, particularly against colon and lung cancers", "High in vitamin K (bone health) and vitamin C", "Good source of folate, calcium, and potassium", "Traditionally used as a digestive aid and 'salad green' stimulant in Roman times", "Contains nitrates beneficial for cardiovascular health and exercise performance"]

📝 Notes

Arugula (also called rocket/roquette/rucola) is one of the fastest crops — harvest in 21–40 days. Two main types: standard garden arugula (lobed leaves, peppery) and wild arugula (Diplotaxis tenuifolia — narrower leaves, more pungent, perennial in warm zones). Succession plant every 2–3 weeks for continuous harvest. Bolts rapidly in heat above 75°F — grow as spring/fall crop. Flowers are edible and attract pollinators. Flea beetles are the #1 pest — floating row covers prevent them. Self-seeds readily if allowed to flower.
