Landscaping in Las Vegas is gravel, drip, caliche, and a sun that kills the wrong plant in a single west afternoon. Artificial turf looks simple until it becomes too hot to use. A tree that would be ordinary in a milder city scorches against a block wall. Irrigation is not a backup. It is the only water the yard will get, because rain is not a plan. When rain does come, it comes hard, and a grade that looked fine in the dry months runs straight at the slab and the stucco. Wind adds grit and tips over anything shallow.
Say the job without a catalog. A weekly clean, a dead tree on the tile, a wash through the rock, emitters that drowned one plant and starved the next, or a new planting. Ask who moves drip as plants grow, and who is responsible if a shrub dies in the establishment heat. Ask whether the work changes grade. Decorative rock piled against the house is how water and scorpions both get a reservation. Keep limbs off a roof that is already baked, and keep water off the condenser pad.
Caliche will stop a shovel and send water sideways. If you have already hit it, say so. If the lot touches a wash, say that too, because the edge is not a normal bed. Pool decks and equipment pads need drainage that does not dump on the house. Haul-away should be explicit. A rock yard still grows weeds after a rare rain, so ask what a maintenance visit actually includes in a dry month versus a weedy month.
Do not propose a lawn as if this were a mountain town with a short green season, and do not propose a monsoon garden as if the storms were reliable. This yard lives on drip and shade structure. Call the number on this page.
