Landscaping in Nevada is rock and drip in the south, and a short, cold growing season in the north, with wind in both. Southern yards are caliche, gravel, a few tortured trees, and artificial turf that gets hot enough to regret. Northern yards can hold a lawn through a brief summer and then spend winter under snow, with spring mud and wind that desiccate whatever leafed out too early. Water is the constraint almost everywhere it is scarce, which is most of the state. A lush plan copied from a wetter place will fail in public.
Say the job. Weekly trim, a dead tree on the roof, a wash cutting through the gravel, or a new drip zone. In the south, grade matters because the rare rain falls all at once and runs to the slab if the rock is pitched wrong. In the north, grade matters because snowmelt and spring wet sit against a foundation. Ask whether the work changes that pitch. Ask who maintains emitters after the crew leaves, and who replaces a plant that cooks or freezes in the establishment season.
Trees are a sewer and roof question where trees can live. In many southern yards the better question is whether a tree should be there at all on a west exposure. Keep limbs off roofs that are already sun-baked. In the north, keep limbs off roofs that take snow, and ask how debris will be hauled. Rural lots should mention defensible space in plain language: what is growing against the wall, and what you want cut back, without turning the call into a speech.
The calendar is not optional. Southern planting into peak heat is a gamble. Northern planting has a short window between frost and drought. Name the town, the soil if you have hit caliche or clay, and the work. Call the number on this page.
