I am sorry for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!
Those air plants are a problem unique to your region of the country. I suggest you take a sample of the plants to your County Extension Office and so they can identify the specific plants and then prescribe an appropriate remedy.
Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
