[Collapse all sections] Summary

"What the threatened lawn must do is take advantage of what makes it different from the weed. For where weeds are, par excellence, solitary hunters, lawn grass is overwhelmingly a tightly grouped species. Most grass blades on your lawn are over eight months old, and some will be over twenty months old. But even more importantly, the whole community of lawn grass might have been growing in the same place for years. And in that time, all stable and steady, it will have had time to acquire friends. Lots and lots of minature friends." [goes on to mention bacteria and fungus]

"There's an entire cabled-up network under your lawn, connecting all the grass roots. It's been building up for the whole life of your lawn and by now can easily shunt liquid food supplies from a well-supplied sector to a threatened one. The weed, though tracking the sun with its antenna and trying like mad to grow fresh roots of its own, can't compete with a system this large and long-established…A single square yard of lawn planted with Kentucky bluegrass can have ten billion root probes. Even if only a fraction of them have had time to build up the connecting fungus cables, that's still many millions of links, and so an extraordinary volume of subterranean space from which any threatened grass blade can, via the shunting network, draw help." (Bodanis 1992:165)
