Two years before the grass

We've wanted to give buffalo grass (Buchloe dactyloides) a try in place of the St Augustine (with a trace of Bermuda) in our small backyard lawn once the declining shade trees came down. It was highly recommended to spend a good portion of a year when feasible making sure the old turf really is dead and gone - especially where Bermuda is involved. So, we turned off the sprinklers and lightly solarized almost all of the turf by mid-summer 2014.... before realizing scheduled home repairs would have contractors rolling around much of the backyard into 2015.... oops. What we decided to do was just let any forbs not recognized as obnoxious "weeds" grow and continue to pull or spot treat (with glyphosate) the turf or weed grasses as they reappeared. The following photos are a walk through these adhoc transitions.

Forbs and vines established by September 2014 included various morning glory/bindweed, honeyvine (Cynanchum laeve), scarlet sage (salvia coccinea), and the blue wild petunia (Ruellia nudiflora). The Mexican hat (Ratibida columnifera) and Turkscap (Malvaviscus arboreus) were natives that escaped from the borders. American germander (Teucrium canadense), Whitemouth dayflower (commelina erecta), Texas dandelion (Pyrrhopappus pauciflorus), and clasping Venus's looking glass (Triodanis perfoliata) were some of the others that appeared at some point, but not clearly visible at the time of this photo. The pepper plant was a critter gift from the compost pile and yielded well:

By mid-May 2015, scions of our two Barton Springs Nursery Ratibidas had largely taken over the bare clay (they were not nearly as aggressive when there was turf) :

Right after this mid-June 2015 photo, we cut them down before the seeds could set:
The Ratibidas are such hardy tap-root plants, they served as a sparse fern-like ground-cover after mowing until we tilled them under (or out) and seeded with annual ryegrass in the early fall 2015 for cover over the winter months. Ryegrass appearance was in decline by the time we tilled it under as (sort of) green manure right after this photo in late March 2016:
Would have wasted too much sod on this small area with a pallet as the minimum order size, so went with three trays of 'Prestige' plugs at 12" spacing. Would not want to do a larger space this way - or another small one without better weed prevention. This was just after being plugged on April 5th, 2016:
Several sources said to apply a pre-emergent, but the product instructions said not to use on fresh plugs. So made a wimpy compromise and applied a half-strength dose which didn't do anything for the dusting of crab/dallis/??? grass seeds our pots and bare soil had received. Would not make that mistake again. Not sure we would have had the time to keep ahead of the grassy weeds in a much larger area. The whole space was covered like this at about five weeks:
It was close to eight weeks (6/1) before the plugs broke dormancy and really started filling in:
Was dog approved at week ten:
And well filled in by week twelve... which was the grower/nursery estimate:
Obviously too soon to tell how it will do year-round, but so far really like the texture and its natural sculpturing that moves with the wind. Probably still at least a couple weeks off from the first cut. Now on to the neglected borders.....
