This is my favorite grass for my area (Charleston, SC). In fact, in SC this grass is known as Charleston Grass. It grows quickly and tolerates considerable neglect and abuse. Just a couple dozen cuttings will quickly cover an entire yard with a thick, lush, cool, blue-green carpet, the kind you will want to walk through with bare feet in summer.

The only downside is that it requires weekly mowing just because it grows so quickly. While I much prefer St Augustine, in my yard I have centipede which grows so slowly it only needs to be mowed 2x/month; centipede is more or less required in my community. But I did plant St Augustine in a few difficult areas of my backyard, areas where centipede refused to grow, areas now covered in a lavish carpet of St Augustine. Love this grass... read more

Hi I actually have a question about how I could remove all the st. Augustine grass from my lawn in order to replace it with native grasses?
I dont want to use a herbacide because they are designed to kill weeds, whereas in my case the st. Augustine grass are the weeds. Ive just been ripping it out in patches and its been very hard on my hands and back. Also it grows back very quickly. I've thought of burning off the areas ive already pulled but I'm sure theres a law against it where I live and since it grows rhizomously I'm not sure fire would be effective. Any tips would be great, like a natural herbacide specific to saint augustine grass?

This is one of the only plants, along with bahia grass, that I completely dislike. It constantly invades any and every space available with thick spongy mats, sometimes a foot high, with impenetrable grass. I struggle to remove it from gardens and it constantly tries to invade the area that I bared, covered with a layer of gravel, then soil to grow native prairie grasses. It also leeches nutrients from the soil. Areas in my backyard that used to have it before it was shaded out are all gray dusty rocky soils that stay dry and compacted all Summer and become a sloppy muck, sometimes a foot deep during the rainy months of Winter. The areas are completely bare and all attempts to cultivate them with topsoil, mulch, leaves, pea gravel, sand, etc. have failed. I would much rather somethin... read more

Most popular lawn grass for the gulf coast. It is very lush and thick when mowed high, but tends to need dethatching fairly often. It also performs well in the shade. I have noticed brown patches, but I think the fault lies with grubs.

It is the most common lawn grass grown in Richmond. Prone to brown patch. Would rate it positive because it's lush and thick, but the yearly brown patch makes the yard look ugly and unkempt.

When wanted, this grass makes a beautiful, thick, hardy lawn covering. Drought and heat tolerant. When unwanted, it is difficult to kill.
