If these beds do not have annuals such as impatiens, Ronstar Flo can be combined with the Scythe. I regularly use this to control weeds in landscape beds. Ronstar is not only a preemergent, but when applied to prostrate broadleaf weeds, it will fry them. Do not ever spray this over the top of shrubs. You will defoliate the plants. Ronstar granule does not work the same and costs $400+ per acre treated, so I use the flowable.

Beach front bed contains Oleanders, Hollywood Junipers, Red Cedars, Pittosporums, Wax Myrtles and native beach grasses. Will your suggestions work on that? Sounds like it. And thank you.

I think a tank mix of Scythe and Ronstar will work if those are the ornamentals. All of those plants are tolerant of a directed application of Ronstar. Set up a wand with a fan tip to apply 2 gallons/M and put down 2.5 oz of Ronstar Flo with 8 oz of Scythe. The fun is watching weeds burn up in an hour. This works much better than glyphosate and is much safer for the shrubs. Glyphosate will kill or damage everything in the bed if it drifts and it does nothing for the seed bank in the soil. You will be exposing the plants to glyphosate over and over again. I know when a landscape has been maintained with RoundUp. Many of the plants show glyphosate damage on the new shoots.
