Hello, I have 3 rows of pine trees that are planted fairly close together, and are mature and have shaded undergrowth. There is a few things growing like poison ivy and other types of weeds, but I'd like to get some kind of ground cover that will cover it well, and choke out weeds and give a little protection from fire. An idea that I a come accross was Sweet Woodruff. Is that a good option? Other ideas? I will include some pictures.
