We have just moved into a new place on south padre island with a small backyard and we are in the process of trying to plant grass. So far we have weeded most of the area but we have stumbled upon what seems to be a pretty aggressive plant. It is everywhere underneath our soil/sand. I can not stick the shovel into the ground with out cutting into 1 to 5 of these. Their thorns have some sort of toxin if you prick your finger on them. So far I've found this running as far as 18 inches deep at this point. The longest one I have been able to pull up has been about 13 feet before it broke off and they seem to go quite deep as well. Should we till this area, chop it up and rake it? From what I've been finding it looks like blackbrush acacia or catclaw acacia. Any help towards getting rid of these would be much appreciated. On a side note, with our backyard not getting a great amount of sunlight any suggestions on what grass to go with?
