Mastercare Landscape & Design Inc in Carlsbad's La Costa corridor specializes in maintenance and design for large residential properties across Rancho Santa Fe, Olivenhain, and the La Costa estates. Irrigation overhauls, hardscape installation, and full softscape programs serve the same estate-scale lots where pool contractors such as Premier Pools & Spas San Diego build custom watershape projects. Incorporated in California in 2020 and headquartered on El Camino Real near the Omni La Costa Resort, the firm manages recurring service contracts that cover sod, pavers, and seasonal planting rotations for North County properties exceeding half an acre. Integrated pest-management scheduling aligns treatment windows with the lawn-care cycles that specialists at White Knight Pest Services run on adjacent turf and ornamental beds. Design-build packages include grading for positive drainage, Hunter MP Rotator head layouts calibrated to matched-precipitation rates, and MWELO-compliant planting plans that meet the City of Carlsbad's water-efficient landscape ordinance.
