Ragweed are largely native to the Americans but also naturalized across Africa, Asia and Europe. They are tough and can survive in very poor soil. They are also commonly known as bursages and burrobrushes. The pollen of ragweed is a primary cause of allergies in humans.
Water:
Ragweed thrives in moderate hydration cycles, adapting to wet and dry seasonal patterns. It withstands brief droughts but requires weekly watering for optimal growth. Predominantly an outdoor plant, it needs adequate moisture during the growing season for robust health and development.
Propagation:
Ragweed propagates primarily through seed sowing, requiring full to partial sun, temperatures of 21-29°C (70-85°F), and well-drained soil. Seeds need light for germination, typically sprouting in 1-2 weeks. Care must be taken to manage its invasive growth post-propagation.
