Conventional turf and ornamental landscaping in Houston is expensive to maintain not because the plants are particularly demanding by the standards of other climates, but because they are fundamentally mismatched to the conditions Houston actually delivers. Houston's clay soils restrict drainage, making roots shallow and vulnerable to heat stress during dry periods. Periodic drought cycles, which have increased in frequency and intensity across the region over the past two decades, push irrigation demands well beyond what a normal supplemental schedule delivers.
According to the Texas Water Development Board, outdoor landscape irrigation accounts for approximately 30 percent of residential water use in Texas on average, with that figure climbing significantly during drought events when supplemental irrigation carries the entire load. The 2011 drought alone caused an estimated five billion dollars in agricultural and landscape losses across Texas, and residential lawns across the Houston area were among the most visible casualties. Drought-tolerant landscaping addresses these costs at the source by replacing the plants generating the highest water demand with species that evolved to handle exactly these conditions.
