Q.Horse or Mares Tail
I have this plant popping up all over the garden every year. I understand it spreads through the roots so chemical control is out of the question. It comes in from the field and hedgerow so I will never be able to stop it. Current method is to pull up each frond as I see it and dispose of in the council green bin. Does this keep it under control or encourage it to spread more ?
