NORWICH — Jacob Mann started with 14 tomato seedlings and a rusted trailer frame hitched to a pushbike.
Today, the 14-year-old schoolboy manages a commercial nursery footprint of 7,000 tomato plants from his backyard greenhouse in Norwich, shipping customized growing kits across the United Kingdom and as far abroad as Australia. He built the entire venture between homework shifts.
The enterprise, branded The Tomato Cart, began during pandemic lockdowns when a casual family gardening contest revealed his distinct horticultural touch. While his siblings' plots withered, Mann’s flourished. Ambition followed quickly. When his brother secured a morning paper route to earn pocket money, Mann decided to build his own venture around edible crops rather than take up an entry-level wage job. Two days before turning 13 in December 2024, he hauled home a free glass greenhouse sourced through Freecycle, alongside a secondhand trailer base purchased on Gumtree with savings. He and his father bolted the frame together, rigged it to his bicycle, and began hawking plants at local car boot sales.
Sales surged rapidly.
Mann quickly exhausted his local street inventory, pushing his production schedule to industrial volumes. Operating out of his home setup, the teenager wakes at dawn to water trays before morning classes, relying on family support to monitor ventilation and keep commercial commitments from clashing with schoolwork. Unpredictable British weather forced early operational adjustments—including installing dedicated greenhouse heaters after freezing nights initially required hauling hundreds of vulnerable seedlings indoors by hand.
The enterprise has since diversified away from raw, perishable nursery stocks by leveraging online storefronts on Etsy alongside its direct web portal.

Mann also expanded his seed portfolio beyond basic supermarket cultivars, collaborating with horticulturist Nick at JustSeed to curate rare heritage strains. His public profile grew in tandem, earning him invitations to regional agricultural broadcasts and an appearance at the RHS Sandringham Flower Show, where he traded notes with established landscape figures Alan Titchmarsh and Rekha Mistry.
Yet the operational core remains grounded in nursery logistics. As the spring planting season accelerates, Mann is fulfilling advance pre-orders and preparing his bicycle trailer for regional market rounds, targeting his next expansion phase: establishing a permanent independent commercial garden centre.
