I think its mares tail reminds me of christmas trees. My new garden is full of it and I wondered what is the best way to get rid of it and keeping it away as I have heard it is a nightmare to get rid of.
While this site offers some solutions like this one;
"Without resorting to chemicals you can control/irradicate horse tail by digging/forking through the soil when it is in the right condition: ie not too wet and sticky!
Once you have removed as much as possible, any that shoots is easily dealt with. Before it reaches 3 ins/7cm high, hoe off an inch below the surface.
Eventually the food supply in the root is exhausted. Let it get bigger than stated and food begins to be stored in the roots again, and round and round you go ad infinitum.
Never touch Horsetail with a mechanical cultivator. If you do you will understand why it has been around for 60 million years";
