duganderson Posted November 3, 2012 Share Posted November 3, 2012 Any idea what this green thing in the middle of the photo is? It's about 1/2" tall. Is it a pest.....should I kill it.......how??? Link to comment
lakshwadeep Posted November 4, 2012 Share Posted November 4, 2012 It looks like Halimeda, a calcareous algae. They aren't a big problem and are fairly easy to prune. Link to comment
