Replated some of the C. aurantiaca to give them some room. Unfortunately, being sowed so thickly they are essentially a fused mass which makes separating them difficult at best.
Oh well, you'll be able to separate them better when they're bigger... or not. If your climate were different, you could aspire to replace the lawn. But where you live, not an option.
That’s my hope. But they are literally consuming the medium and I figure it will be gone before they get much bigger. Its level is dissipating and the roots are taking its place! This is the bottom of one of the plates.
