First you need to decide what kind of grass you want to have. I can decide that for you from 2,000 miles away if you like. Here it is. You want St Augustine. You probably want the variety called Floratam developed by the University of Florda and Texas A&M University (hence Floratam). The only way to grow new St Augustine grass is by sodding it. Since you are basically starting over, I would hire a landscaper with a tractor and a box blade (NOT a skid steer or a bobcat) to come in and scrape the surface of the entire yard. This will even out all the bumps and fill the holes to provide a perfectly draining surface ready for sodding. Then have the sod delivered. Gather all your friends so the sod can go down all at once on the day it is delivered (PIZZA party). Then roll the sod down with a rented, water fillable, roller. Water it morning, noon, and night for 3 weeks to knit the roots from the sod to the underlying soil. Set your mower for the highest setting and mow when the grass is at least 4 inches high. Eventually all the grass will grow up to that height and it will look excellent. Never lower your mower for any reason. St Aug needs 1 inch of water per week to stay alive. Ideally that inch will be applied on one day. The frequent watering is ONLY for establishing new roots. If it turns straw colored, it's dead. But if you have one living plant left in the yard, you can restore the entire lawn from that one strand of grass. It really takes weeks of full sun and no water to kill it off, so almost any care will keep the grass alive. But if you want it to look nice you need to water weekly and mow weekly. I fertilize with organic fertilizer 5 times per year on the federal holidays. If you use synthetic fertilizer you can skip the 4th of July app because it is really too hot. If, after this type of renovation, you still have weeds, we can talk about it. I think they will almost all be gone, though.

Why not kill the vine with kindness? Fill jars with dilute Roundup solution (3 parts water, I part Roundup), place ends of vines in the jars through holes in the lids and seal the jars by twisting the jar, not the lid. The jars can be hidden by shrubs or other vegetation. The vines will gladly take up the Roundup/water solution and be grateful for the additional water. Top off the solution in the jars as needed with additional solution as the vines take in the water and transport the roundup into their roots. Next year, the vines will be very unhealthy if they even survive the winter. Repeat the second year if necessary. All the roots are probably interconnected, so all parts of the vine in your yard and the neighborâÂÂs yard will eventually die. Commiserate with the neighbors when they express sadness over the unexplained death of their beloved vine.

One of the henbits; Lamium purpureum or L. amplexicaule. Pretty purple blooms but once you see the purple color you are sure to see it again next year. These are winter annuals that need to be controlled first in the fall and then again in the late winter (chemically, which you can't). Looks like some control has already been applied by maybe extreme winter cold or severe drought??? (scorch on leaves) but not sure. Doesn't seem to do well competing with healthy turf, so overseeding in fall and thickening the turf may be a help. hortster

The easiest way to ID weedy grasses is from the inflorescence, the seed producing stalk. Compare your weed to Dallisgrass, you could also try asking on the grasses forum or Name That Plant. Good luck!
