Organic can run off too. As well as cause problems. Mechanical work means more, IMO: aerating, solving drainage, topdressing, plant selection, etc. Which is why I mentioned, but forget to say why: buried trash can cause hot spots (patches that dry out too quickly).
Sounds good, looks good, ccshfr! May be a supplier of worms in your area. I think it is 5-lbs per 100 s/f for lawn distribution. Worms are the key, IMO, and their presence seems to bring everything else that is good (birds, toads, etc).
I've always admired
Sahara but always thought of it as a western versus southwestern mixture. I'll be trying
TEX*ACE by East Texas Seed Co in the spring.
As for bulk compost and mulch, there is no substitute to having truckload deliveries; 3, 6 or nine yards at a time. I used such to build the lawn (at one house, badly neglected for years)
by eliminating all sharp corners on lawn (no "pull back" on lawn mower when mowing) and then, once lawn perimeter established, used compost topped by mulch around house, fence (both sides), etc. The compost/mulch was like a nutrient bank: Just water and allow to run into lawn. Broke down after first year, but lawn was like new afterwards (old fence, slab foundation house).
My landscape method is: eliminate lawn bit bit, with landscaping on all areas of the house. I work my way in from the property line or fence; and outwards from the house and other structures. Wind up with lawn as "connector" to different areas, and super-easy to mow (no wasted motion due to layout).
I'm still waiting on the aeration guy (fifth "appointment"), and my bags of sand are waiting to go to replace the cores in the sunniest areas of the lawn.
Cibolo, huh? Out near Scherz? Man, you lucky dog . . only a half-hour away from one of our top-three favorite BBQ joints: City Market in Luling:
