theres about as much root as grass with that stuff the roots are white .I planted mine awhile ago & still find a bit every morning floating ,looks great in the 10 gal refuge though. I find the roots pull out if jiggled by curious fish because the plants sometimes trap food. my dwarffrogs try to get under it. but they are too cute to remove in either case. gotta love a nice patch of aquarium lawn , its like a front yard for your fish. My dwarf hairgrass comes attatched to sandy mud so ive only tried to tuck it into the substrate in clumps (it comes as sod if you slice it out nice with your fingers) best under the edges of large decorations like rock or wood ,tuck grass under the edged so the roots are coverred but the green tops catch light
