Lawn Alternatives for San Juan, PR

Lawn alternatives here are about escaping the mowing treadmill as much as saving water. Ground cover mixes, clover, and micro clover blends offer lush, year-round green in San Juan with dramatically less maintenance than the bermuda or St. Augustine grass that dominates most tropical lawns.
