Notes:

Not sure what any of the three weeds are. Photo 1 has long slender tuber leaves or strands. Need to know how to control all three. St. Augustine lawn.

    These are warm season annual grassy weeds, some species of crabgrass or stiltgrass. They are best controlled by timely application of pre emergents in early Spring. Post emergent control of grassy weeds in St. Augustine is tricky because it is sensitive to many chemicals. I don’t know if any products are available to the general public to fill this niche as I mostly tend bermuda and zoysia. These weeds seed aggressively and part of your management plan should be to bag clippings while these weeds are present to remove as many seeds as possible. This will help with control next year. Pros should have access to celsius and certainty herbicides which will provide adequate postemergent control in St. Augustine turf, though you might have to pay extra for it. A pro who deals with St. Augustine more often might know of an even better control product.
