Founded in 1995, PB's Greenthumb Landscape and Hardscape Design Carlsbad produces 3D-rendered site plans and full-scope outdoor construction from its Avenida Encinas office near Poinsettia Park. The design team specifies low-voltage lighting layouts using manufacturer catalogs from suppliers including Auroralight, integrating path, accent, and up-light fixtures into paver and retaining-wall installations. Services span landscape design, hardscape construction, custom fire pits, outdoor kitchens, pool-surround landscaping, and synthetic-turf installation for properties across Carlsbad, Encinitas, Del Mar, and Rancho Santa Fe. The BBB-accredited firm operates from four regional offices and holds a GuildQuality feedback profile that tracks post-project satisfaction across communication, workmanship, and schedule-adherence metrics. Pre-treatment of soil and drainage beds during new landscape installations coordinates with pest-management providers such as Thrasher Pest Control to address subterranean termite barriers around wood structures. Retaining-wall systems use segmental concrete units rated to 4,000 PSI compressive strength, set on six-inch compacted road-base footings with geogrid reinforcement layers spaced at 16-inch vertical intervals.
