My E. Polaris seems to be growing randomly like hairgrass, unlike the very orderly growth of the E. Cinerum I've seen in other journals . As this will be my first time propagating this plant, could I check whether this plant is ready to be divided and can I divide it along the red line indicated. or do I need to wait for it to grow bigger? I've seen the 2hr Aquarist article but the sample pics are quite types of Erios, so just checking....
