Germination & Seedling
2-3 weeksSeeds sprout in 7-10 days; cotyledons emerge followed by first true leaves; seedlings are delicate with thin stems
Keep soil warm (70-80°F) and consistently moist; thin seedlings to 12 inches apart; provide bright light to prevent leggy growth
Vegetative Growth
3-4 weeksPlant develops multiple stems and leaves; foliage becomes dense and bushy; leaves are tender and ideal for harvest
Water regularly; apply balanced fertilizer every 2-3 weeks; remove any yellowing lower leaves; pinch growing tips to encourage bushiness
Leaf Production & Early Harvest
4-8 weeksContinuous production of tender leaves suitable for harvesting; plant reaches 2-3 feet tall; leaves remain tender during cool-season growth
Begin harvesting outer leaves when plant is 6-8 inches tall; harvest regularly to encourage continued leaf production; side-dress with compost monthly
Peak Production
6-12 weeksPlant is fully established and producing abundant tender leaves; foliage is lush and deep green
Harvest frequently (every 3-5 days) to maintain tender leaf quality; continue regular watering and fertilizing; watch for bolting in extreme heat
Senescence & Bolting
End of seasonPlant begins to flower and set seed; leaves become tougher and less palatable; foliage quality declines
Pinch off flower buds to extend leaf production; consider replanting for continuous harvest; allow some plants to flower for seed collection if desired

Harvest Tips
Begin harvesting outer leaves when plant reaches 6-8 inches tall (approximately 30-40 days after planting). Pinch off the top 4-6 inches of stem with tender leaves; this encourages bushy growth. Harvest frequently (every 3-5 days) to maintain tender leaf quality and prevent bolting. Young leaves are most tender and preferred; older leaves become tougher. In tropical regions, calaloo can be harvested continuously year-round. Cut leaves just above a leaf node to encourage branching.
Fun Facts
- 🌱 Calaloo is known by many regional names including 'bhaji' in South Asia, 'jambu' in West Africa, and 'callaloo' or 'calalu' in the Caribbean, reflecting its importance across multiple continents and cultures.
- 🌱 The plant belongs to the amaranth family and is closely related to grain amaranth; both the leaves (used as greens) and seeds (used as a grain) are edible, making it a dual-purpose crop.
- 🌱 Calaloo grows so vigorously in warm climates that it can self-seed and return year after year; in some regions it is considered a semi-perennial that can produce for multiple seasons if protected from frost.
