Answer: If the weed has a single stem, the stem has sections like bamboo, and the foilage looks like pine tree needles, I suspect your weed is Equisetum, also called horsetail. These weeds sprout from underground rhizomes and are difficult to control because of their depth in the soil. The best course of action is to keep cutting down the sprouts as they appear. Eventually the roots and rhizomes will run out of energy to produce new sprouts.
