Pulsating Xenia

Does anybody know to trim pulsating xenia down from touching my GSP. When fully extended they close up as they are touching. They touch my toadstool but they don't bother each other polyps fully extended on both. Do I pull them off or cut them in half.

I cant post pictures cause the site wont let me. I get this (Failed to write file. Check disc quotas and permissions for the path)
