If you specialize in creating drought-resistant yards, your skills are likely to be in high demand.

Xeriscaping is a type of landscaping that incorporates stone pathways, mulch and native plants like lilac or coffee berry -- all of which use significantly less water.

It's particularly relevant in California, where homeowners are struggling with a protracted drought, but is popular in other pockets around the country as well.

While the searches for Xeriscaping have held steady, the number of entrepreneurs listed for this service has jumped 92% over last year.

Albert Sanchez owns Daka Lawn and Landscaping business in San Antonio, Texas.

"We're booked out solid the next four to five weeks," said Sanchez, who charges $1,500 to $2,500 per job.

He said xeriscaping has taken off in the last few years, fueled in part by the upturn in the housing market.

"Curb appeal is very important for both selling and renting a house," said Sanchez. "Dead grass and shrubs aren't appealing."

Xeriscaping also significantly reduces maintenance cost.

"Some residents we know cut water [consumption] costs from $60 to $15 a month after xeriscaping their lawn," he said.
