Founder Story
Bruce Jamieson’s journey in horticulture began in 1982 at Mount Albert Grammar School, where he first studied horticulture and agriculture. What started as a school subject quickly grew into a lifelong passion. After completing an apprenticeship in a plant nursery, Bruce went on to study horticulture at Massey University, building a strong foundation in plant and soil health.
Over the next four decades, Bruce gained hands-on experience across every level of the industry. He spent time working in Australia with several landscaping companies before starting his own landscape gardening business in Sydney. These years helped shape his practical, results-focused approach to plant care — knowledge that would later become the backbone of his own business.
On returning to New Zealand, Bruce founded New Leaf Horticulture Limited. Seeing a gap in the market, he became the first in the Auckland region to offer a professional spraying service tailored specifically for plant nurseries and garden centres. As word spread and demand grew, the service naturally expanded into residential gardens, allowing Bruce to bring professional-grade care directly into people’s homes.
In 2003, Bruce developed the Aquaticus fertiliser range, born out of years of trial, observation, and real-world use. Today, Aquaticus products are stocked by leading garden centres including Kings Plant Barn and Palmers Garden World, and they form a key part of the treatments used by the business.
In 2023, the business evolved into Garden Boosters, with the service previously known as New Leaf Horticulture Limited now trading under the Garden Boosters name. Backed by over 43 years of experience, Garden Boosters continues Bruce’s commitment to healthier plants, better soils, and practical solutions that deliver real results.

Garden Booster story
Rophe’s journey with Garden Boosters began long before he ever worked in gardens across New Zealand. Born and raised in Samoa, he grew up in a culture where hard work, respect, and taking pride in what you do were part of everyday life. These values shaped his character early on and continue to guide the way he approaches his work today.
When Rophe moved to New Zealand, he brought his strong work ethic with him and quickly found his passion for hands-on, outdoor work that produces real results. At Garden Boosters, he thrives as part of a skilled, supportive team, collaborating on tailored solutions for every garden while sharpening his technical expertise and commitment to delivering reliable, high-quality service.
Through his work, he has also developed strong customer service and communication skills. He understands the importance of trust, reliability, and clear advice, and takes pride in building positive relationships with clients. Garden Boosters has further provided him with the opportunity to manage and run his own business, allowing him to grow as a professional while taking full responsibility for the quality of his work.
Today, Rophe remains committed to delivering long-term results for every garden he works in. His story is one of growth, dedication, and respect for both people and plants—values that continue to define his work and reflect the standards of Garden Boosters.
