Cocklebur (Xanthium canadense) must be prevented from seedingand to do this considerable watchfulness is necessary, as the plantsgrow rapidly and produce seed when very young. This is especiallytrue in the fall when the cockleburs are apt to come up and go toseed unnoticed. They should be pulled up as soon as seen and ifseed have formed they should be burned.

Theprocess of cutting down this weed as often as it appears above groundis a very tedious one, but if conscientiously followed will be success-ful. The easiest and cheapest way, perhaps, is to plant alfalfa andcut hay two years. This will reduce the hand work to the wild aspara-gus along the ditches and under the fences.
