J S Agriculture Ltd was founded in 1982 by John Straka. The business began as a small grounds maintenance service for private clients. Within a few years, the company secured its first major commercial contract with British Gas Transco. This marked the start of steady growth into larger projects.
By 1992, demand had increased. John Straka chose to focus on large-scale work for well-known companies. Investment in modern machinery, equipment and staff training helped expand the company’s capabilities. This allowed JSA to take on more complex projects and continue growing into the twenty-first century.


JSA developed along two main service areas:
- ➜Grounds maintenance for larger organisations and high-profile clients. Our trained horticultural team delivers careful, detail-focused work across a wide range of sites.
- ➜Specialist landscape and conservation services using advanced agricultural machinery. Ongoing staff training and continued investment in equipment help maintain high standards.
In 2012, John’s stepson joined the company as an apprentice. Over time, he progressed through the business and now works as Projects and Contracts Manager. He works closely with John to manage operations and support the future of the company.
Today, JSA provides a wide range of land management services across the UK, including:
- ➜Conservation management, including grass and wildflower meadow maintenance and weed control.
- ➜Arboricultural services and tree maintenance
- ➜Hard and soft landscaping
- ➜Grounds maintenance for offices, hotels and business parks
With decades of experience, JSA has built a strong reputation for reliability, skill and consistent quality. We deliver professional services for both private and commercial clients across the UK.
