Southeast Louisiana---I am constantly pulling weeds out of my garden. What is the best groundcover to eliminate weeds? Suggestions please.

Pine Needles

thick layer of pine needles…way thicker than you think. Pile them deep between the plants and keep them wet.
Grass clippings also make a tremendous weed barrier, they mat up and stay put. If you really want to go medieval put a layer of wet cardboard down first

We have some juniper and a hardly ever see weeds coming up through it

We have some low growing Blue Carpet creeping juniper and hardly ever see weeds coming up through it. But we’ve had it a long time and it’s all grown together, so there are no gaps in it.

Not sure how this would work, but monkey grass seems to keep everything else from growing

I can attest to the fact that this works.

I have a bed that I tried to keep weeds out. One thing I tried was not discharging in that direction. Eventually gave up and shot clippings into the bed from East and West. Weeds went from terribly time consuming to pulling a handful monthly.

Monkey Grass
I have nice areas of very dense monkey grass, 20+ year-old patches. It excludes weeds with two exceptions: dollar weed and torpedo grass. When either of those show up, I hand remove it after cutting chuck's of MG turf. Fortunately, the weed roots are easily found in the dense MG turf. Dollar weed initially makes a good contrast in MG, but remove runners before seed set.
When starting MG, try to use larger dense plugs and mulch heavily between them. Chopped pine needle mulch at 2" thick is most effective.

yes!
shoot the clippings into the beds not away from them. The clippings will build up and form a dense organic barrier that also feeds the bed

You can also use pre-emergent herbicides, in addition to thick layer of mulch, to help suppress (you’ll never “eliminate” weeds) annual warm season & cool weeds in landscape beds, though pre-emergent herbicides won’t help with many grassy weeds, sedges or perennial weeds.

I use Geo fabric, 5 lb minimum, it lasts about 3-4 growing seasons (2 years) then needs to be replaced. I will up my rows, put down drip irrigation, lay the fabric out then use a map gas torch to burn holes where I want plants. I have used this for 3 years with success. Be sure to get the fabric that allows water to pass through.

Works great, until the racoons get to work. Now, I need to find something to putdown for ground cover and to get the racoons to stop tearing it up
