I have desert landscaping but crabgrass will pop up from time to time.
Crab grass is mostly adapted to arid regions and poorly drained, underfertilised soils, some species serve also as food (fonio) or animal fodder:

A bit of it.
No, we have mostly pachysandra and ivy for a lawn.
The crabgrass doesn't have a chance.
