Answer 1

Propagation of Ragweed is through seed.

giant ragweed: Most burs fall near the parent plant, but some can diperse long distances with water, animals, and human activities. Burs are rarely consumed by animals. An average size plant produces roughly 275 seeds. Newly matured seed is usually dormant and requires a cold, moist period to germinate. Seeds typically germinate at temperatures between 8-41º C (46-106ºF), optimum 10-24 º C (50-75º F). Most germination in the field occurs early to mid-spring and at soil depths to 16 cm, optimal 2 cm. Germination rarely occurs on the soil surface. Seedlings emerging from shallow depths are most likely to survive. Plants effectively compete other species for light.

Answer 2

Since both ragweed and cheat grass grow in abundance around here (northeastern Nevada, USA) you would do best to mimic this environment, which shouldn't be too hard. Grow it in a place that gets very little water and lots of harsh, direct sunlight. Make sure it freezes at night and nearly broils in the daytime. You should have a healthy crop of the horrible stuff in no time. It should be interesting to see how your neighbors run you out of the town once this noxious weed takes hold on your block and they find out you're the one who started it.

Answer 3

Why would you even want to? It is a plant which causes many to suffer because of allergic reactions to it.
