Frank Crandall Horticultural Solutions is a Charlestown, Rhode Island landscape design and installation shop built around one name: Frank Crandall himself, who by the 2010s had become enough of an authority in organic land care that regional conferences kept booking him as an instructor, teaching landscape ecology and organic methods alongside other program leaders in Rhode Island and Connecticut. A 2019 industry profile put the scope of his career at more than 35 years, crediting the company at its peak with over $3 million in annual revenue, 30 employees, and 24 landscape design awards. Homeowners who've hired him describe relationships that run for years rather than a single job. One family says he's worked their property for over a decade, including a community-garden project with a local nonprofit; another says he's handled everything from a rain garden to patio drainage fixes over 20 years; a third, writing in a January 2015 review, credits him with landscape plantings dating to the mid-1990s and a driveway rebuild with granite bollards, paver cobbles, and a belgian cobble apron. All three Houzz reviews on file are five stars, but they're also all from January 2015 — there's no more recent written account to point to. He carries several credentials tied to the organic-land-care side of the trade: a Rhode Island arborist's license, a pesticide applicator's license for RI and CT, NOFA's Accredited Organic Land Care Professional designation, and an RI CRMC invasive-plant-management certification. Houzz also lists a Rhode Island contractor registration, #36925, for the company — that's the directory's own record, not something independently verified. BBB has no customer rating on file and the company isn't BBB accredited. This looks like the right call for a homeowner planning organic, ecology-minded landscape design or hardscape work in the Charlestown/Westerly area rather than a quick lawn-care stop — but with the written record running silent since 2015, it's worth a direct call to confirm he's still taking on residential work at the same scope.

Frank Crandall, Horticultural Solutions, LLC has completed landscape design and plantings for my properties since the mid 1990's. He most recently installed extensive hardscapes including granite bollards, walkways, stone walls and terraces. He reshaped our driveway, edged it with paver cobbles, constructed a belgian cobble apron, and resurfaced the drive with natural 3/4" crushed stone. He made modifications and improvements to my landscape design to reflect my preferences in planting while accommodating my desire for a low maintenance landscape. Frank completed installing the new landscape in front, side and rear yard in stages over several seasons. Frank is wonderful to work with. He is knowledgeable, capable, dependable and hard working. He has a keen eye for color, texture and design. The resulting landscape is magnificent. Mary Boyer
