What are my options for grass in edges of beds? Just moved and the beds run right up against the grass and I’m having trouble combatting a little bit of grass growing through the edges. Natural border with bark mulch and mostly hollys lining the beds.

Outside of pulling them every weekend is there something I can spray to keep it down without damaging something subsurface in my beds? Root etc of plants

Can I spray with standard weed killer, or am I risking damage to plants?

Just spray it with weed killer. It will only kill what is sprayed.

I'll hit it anything my weed eater doesn't take care of with weed killer, mainly runners. But every now and then I will walk the edges with my spade to break everything up.

I use glyphosate. A very narrow spray right at the edge. It's not absorbed by the roots. Mostly foliar.

Do you have a proper natural edge? I have mine like the below and rarely get anything growing over that a weekly weed eater pass doesn't take care of.

Probably not defined enough but I’ll work on it. Brand new landscaping before I bought the house last month. Weed eater throws too much mulch so I need a better option there

There is an herbicide called Fusillade that will kill the grass (depending on what your grass is probably) but won't hurt the stuff in the flower beds.

My kid would drop the mower tires right off that edge and scalp the grass

Mostly centipede in the areas I’m targeting.

Glyphosate is only active when it hits plant’s leaves and has no effect on soil. That said, it will kill the entire runner on turf grass, so it will kill grass several inches from where sprayed. I don’t believe that will be defined enough for your application.

The only way would be to install edging and then weedeat.

That looks so nice. It must be AI.


Amazing edge. Id love to have mine like that with my St Augustine. I have to keep the edge up because the HOA wont allow pavers. Yet.

The Bermuda that lurks beneath my weeds would laugh at that nice edge as it climbs over it and proceeds to grow up into those bushes and even up that wall. If it ever rained again, that is.

Geez, won’t allow pavers? You live in the 1940s era Soviet Union?

Keep hitting the edge with your weed eater weekly. It’ll stop throwing mulch after a few weeks and you’ll have your solution.

Comrade, the HOAs in Sarasota county are rebelling against the fact a (R) town voted for orange man in a landslide. ORDER MUST BE MAINTAINED!

Yea, it will change. Our neighborhood is big. Or will be. 900 homes approximately. For now, about 400 are done or being build. That means that the builder is in full control of the HOA and uses a set of rules that most use while they are building. Once enough homes get occupied, then I believe the owners can start to be a part of the HOA and some of that stupid shite will change. That seems to be the way in all the subdivisions down here.

Paver bands prevent DIY homeowners from doing a sloppy job with big box concrete pavers. Uniform curb appeal is the intent. Personally, I like flower bed borders made of half-buried whitewashed tires... once very popular in N MS. Vertical they make a low fence, horizontal a planter. For a while in the 60's near Army bases expended recoilless rifle rounds made nice borders.
