What can i spread on my grass to slow it's growth this summer
getting to old to keep it up, don't want to burn the grass out of course
You can reseed it with a shorter species of grass. Or pay a neighbor kid $20 every other week to mow it.
Gasoline should do the trick.
No fertilizer, no water. Keep it cut to a length of about 3"- nothing I know to 'slow' the growth down
