Yes, you could be bringing some underground horsetail roots to your new farm but do not panic. If you see horsetail sprouting up just take a pair of scissors and cut the shoots to the ground. Then mark the calendar and return to cut these shoots back again in two weeks. Repeat all summer or until the new shoots finally give up and the underground root system dies off from lack of top growth. I was able to eliminate all horse tail on my two acres by constantly cutting the shoots to the ground over one summer. You can corral this galloping weed if you stand tall in that saddle and wrangle those weeds. Keep growing, Marianne Binetti
