Here's a picture of the front - had the idea of ripping out the shrubs on the left foreground, moving the hair grass over far to the left and letting the glosso spread across the front (with some help) - what do you think?
So basically you are trying to get the glosso to spread and not really the hairgrass/micro swords. Every month or so you can check up on all the plants and make sure none are invading the others space
