About Knol Khol Seeds

• Botanical name: Brassica oleracea var. gongylodes
• Care level: Easy
• Expected germination time: 5-10 days at 15-25C under suitable conditions*

How to Grow

1. Fill a seedling tray or small pot with a fine, clean, well-draining seed-starting mix.
2. Sow at the right depth — 1-1.5 cm deep, 20-25 cm apart.
3. Water gently with a spray bottle so the seeds are not displaced. Keep the medium moist, not waterlogged.
4. Place the tray where it gets the right light for this plant (full sun). Protect young seedlings from harsh afternoon sun.
5. Under suitable conditions, sprouts usually appear in 5-10 days at 15-25C.

Light, water, soil and feeding

• Light: Full sun
• Water: Keep the soil always lightly moist — regular watering keeps the knob tender and crack-free.
• Soil: Loose, well-drained loam with plenty of compost.
• Fertiliser: Compost at sowing, then a nitrogen-rich feed every 3 weeks.

Sowing season in India

September–November in North India (rabi); February–March in hill areas. Exact timing depends on your local temperature and conditions.

Common problems

A late harvest turns the knob woody; watch for aphids and cabbage caterpillars.
