Thistles can be controlled by digging and cultivation. This method may be more difficult due to the fact they have hairs that cause a painful irritating sting and spread by underground stems. Thistles are a noxious weed and while not particularly poisonous they are harmful if touched or swallowed. Granular fertilizers and liquid weed control applications will also help turfgrass dominate the lawn and prevent undesirable weeds.
