Question:"During the past three years we have noticed a weed in our lawn which we have been told is yellow hawkweed. It has a deep root and seems to choke out the grass, but it has not spread to any extent. What is the best method of getting rid of this weed?"
Source of Question:Pennsylvania
Answer/Response:"Weeds of this type can often be controlled in small areas by scattering a little sulphate of ammonia on them and burning the crowns. This operation usually has to be repeated two or three times as the plants recover. Sulphate of ammonia not only burns the weed, but also stimulates the grass around it, tends to force a rank growth and crowd up the leaves of the hawkweed so that they are cut by the mower. Various weed killers may be used with success, but as this is a deeprooted weed, repeated applications of most of these chemicals may be required. Sodium chlorate or sodium arsenite may be used to advantage, but we think that sulphate of ammonia should serve the purpose, since you say the weed is limited to a small lawn area."
