Saw ur pix. Nice!! Congrats!!. I wish you culd do that on my lawn. I live in upscale 3 car garaged neighborhood. Due to drought and heat last year, it destroyed some of my grass so does my neighbors too. My old Lawn care service (faithful one!) told me that there's nothing can be done about even you had water often. It's just the heat (KS summer temp can sometime reach 105 to 115 degree w/ humidy on Mid July through August

:-o :-o Just happens few summers. 4 years ago was a really nice cool summer throughout July and Aug!) Right now we're getting more rain this year than ever! Yuppee!!
My home association doesn't award anyone w/ lushious thick green turflike grass. I wish I could dig up and steal their grass. LOL
I fired Chemlawn service (I decide to try new lawncare service due to price increased by my old lawn service) just because I saw dandelion and weeds popping up on my nice lawn

I called and asked what's going on!! They said they forgot to do Weed n Feed application earlier in spring. It's employees cheated on me cuz they did not inform me to unlock the gate. The put fertilizer front lawn and ran off without trying to contact me. I had to cut back lawn service due to fertilizer price rises according to gas price (they do use petroleum to make fertilizer). It's not cheap tho because my lawn is 9,000 sq ft! . I will have to do lawncare myself. Hopefully my grass will look nicer and greener (would use Scott's Super turfbuilder 2

). I have automated lawn sprinkler system so I don't have to lug hoses w/ sprinklers around my lawn LOL.
I plan to adding new flowerbeds and redo exiting flowerbed . I also plan to have bricks around trees. This would means less work mowing lawn. Also may add more trees in backyard for more shades.

I don't use any lawn care chemical services. I notice that the neighbors who do use the services have "rusty" stained sidewalks from the chemical run off.
It's not hard to do your own fertilizer and weed control. We do our own insect control, too.
Part of my personal philosophy is reduce the amount of "lawn." I'm not crazy about large manicured "perfect" lawns. I like just enough lawn for a game of croquet, and to "outline" my flower beds and hardscapes. Hardscapes are wooden decks, brick patios, driveways, porches, flagstone paths, etc. More hardscape equals less lawn equals less maintenance equals less chemicals and water. Also, drought doesn't bother hardscapes.
Someday, I want to replace at least part of my driveway concrete and sidewalk with Lowcountry tabby. It looks so much better than plain concrete. (Tabby is a mix of cement with pieces of seashell, mostly local oyster shells.)

I like dimension in my yard. That means, not everything is viewable from one perspective. There are hidden treasures viewable from different angles.
I also design for the critters (mostly in the back yard). I provide them with feeders, water containers, perches, shade, housing and habitat.
Your irrigation system is a great idea. We don't have a real system but we've done some by ourselves. It does make life easier, for sure. :P
One problem with watering is the water itself. I notice that during the weeks that I water the yard, the grass and plants stay alive but they seem "pale" and weak to me. I think the chemicals in the water are not best for plant life. One night of good natural rain is worth one week of watering. But sometimes the weather doesn't cooperate, huh?
Of course, everyone's water source is different, so it all depends on the area.
I also try to use more native plants, or at least plants (and trees) that are appropriate for my climate zone. I refuse to get any kind of shrub or tree that needs to be covered with a blanket during the winter! If it can't survive in my yard without pampering, then bye-bye.
