The best landscape gardeners in 2024

Whatever your horticultural needs, our list of landscape designers can elevate any green space

By Spear's

Whether it is bringing order to the sprawling grounds of an English stately, or breathing life into a compact London plot, the best landscape gardeners can be relied upon to transform even the most unwelcoming space with their green-fingered expertise.

Among the advisers featured in the Spear’s Landscape Gardeners Index 2024 are designers of gardens for the Natural History Museum and the Royal Academy of Arts, and decorated veterans of the RHS Chelsea Flower Show. 

Although based in the UK and the Middle East, these leading landscape gardeners have reshaped private oases and public spaces around the world, from a wildflower field in Virginia to the manicured displays of Rosewood London.

Methodology

In selecting and ranking gardeners and landscape designers, the Spear’s Research Unit conducts extensive research of the market, including interviews with well-informed observers, industry insiders and of course the advisers themselves. These take place both face-to-face, and on video and telephone calls. Candidates for inclusion are asked to fill in a form to provide data and a description of their work and client base. In finalising its selections and rankings, the Spear’s Research Unit employs a proprietary methodology that includes a weighted scoring system. This takes into account factors including an adviser’s standing, reputation, client base, recommendations and testimonials, the firm they represent, their level of engagement with the process and certain industry-specific criteria.
