hahah that sux. where the hell are you that your growing outdoors this time of year? i would say you probably put it next to an ant nest or they just decided to move in. the ants may or may not affect your plant. idk i would maybe put a moth ball or two on top of the soil and on the ground around it? that might work. im sure as soon as you water it a few times the ants will figure out thats a bad place to live...
