vegetables brassica (leafy green, cole crop)
Illustration of Kale
☀️ Sun
Full sun (6–8 hours); tolerates partial shade better than most vegetables
💧 Water
Medium–high; 1–1.5 inches per week; consistent moisture improves leaf tenderness and flavor
🗺️ Zones
2, 3, 4, 5, 6, 7, 8, 9
🪴 Soil Type
Rich, well-drained loam with high organic matter; kale is more forgiving than other brassicas but still a heavy feeder
🧪 Soil pH
6.0–7.5 (slightly acidic to slightly alkaline)
💧 Drainage
Well-drained; tolerates a range of conditions better than most brassicas
📏 Spacing
12–18 inches apart; rows 24 inches; Italian lacinato/dinosaur kale needs slightly less space than curly types
📅 Days to Maturity
30-60 days (from seed) for baby leaves; 50-75 days for full size

🤝 Companions (7)

Attracts parasitic wasps for cabbage worm control; improves growth
Repels cabbage moths; masks brassica scent
Repels flea beetles and cabbage moths
Trap crop for aphids; cabbage worms prefer nasturtiums to kale
🤝 Chamomile
Improves flavor; antifungal; attracts beneficial insects
Different root depths; kale benefits from minerals beets add to soil
Repels cabbage loopers; conflicting: alliums may inhibit brassicas slightly

⚠️ Keep Apart (3)

Brassica allelopathy may stunt tomatoes
Mutual growth inhibition
⚠️ Beans (conflicting)
Some sources say beans stunt kale; others say kale benefits from nitrogen — most modern sources recommend separation

💊 Medicinal Uses

["One of the most nutrient-dense foods on the planet \u2014 extremely high in vitamins K, A, C, and B6", "Contains sulforaphane (anti-cancer), kaempferol and quercetin (anti-inflammatory flavonoids)", "Exceptional source of lutein and zeaxanthin for eye health", "Contains bile acid sequestrants that can lower cholesterol (steamed kale is especially effective)", "High in calcium (more bioavailable than spinach's oxalate-bound calcium)"]

📝 Notes

Kale is the most cold-hardy brassica — flavor IMPROVES after frost (cold converts starches to sugars, reducing bitterness). Can survive temperatures down to 0°F (-18°C) with protection. Varieties: Curly kale (most common), Lacinato/Dinosaur/Tuscan (dark, bumpy leaves — best for cooking), Red Russian (tender, purple stems — best for salads), Siberian (most cold-hardy). Perennial 'tree kale' varieties exist (Brassica oleracea var. ramosa) — can live 5+ years.
