Growing in Pakistan

Giant Zinnia is a warm-season flower that thrives in Pakistani heat. For Punjab, Sindh, and most plain regions, sow from February–August for continuous blooming through spring, summer, and early autumn. In cooler northern hill areas (Murree, Swat, Hunza), sow March–July. Provide full sun, well-drained soil, and moderate watering at the base (avoid wetting leaves to prevent powdery mildew). Stake tall plants in windy areas. Deadhead spent blooms regularly — the more you cut, the more they bloom.
