Hi, we moved to a new house in October 2020 and have recently noticed some worrying looking weeds. The small tuffle ones have quite stiff stems and seem to be just in the lawn to the back of our house. Whereas the larger root ball was found near the fence in the front garden and seems to go deeper. I've tried Google and don't seem to be getting anywhere. Any help on this would be greatly appreciated. Pictures on link below. Thanks.
