Scotts Miracle-Gro general manager Martin Breddy said his Glee best new product winner Patch Magic had been a long time coming.
"Patch Magic is the first award we've won since Miracle Gro in 1990. That's wrong because if you look at what we've done in the past 20 years a lot has endured more than others' past winners."
He added: "Our advantage is that we have access to global R&D. Our lawn patcher includes coir, which is the key. It expands and creates the perfect growing medium for seed."
Breddy predicts £6m sales for Lawn Patcher in 2010 modelled on US figures.
He added that 50 per cent of the lawn seed market was for patching and 30 per cent for overseeding/thickening, rather than whole lawn coverage.
Breddy said the seed market has been commoditised but he expects the innovation to add 15-20 per cent value to it. Scotts will spend £1m on TV ads pre-Easter nationwide.
Westland launched Plant Rescue, a range of products with an associated text diagnostic service.
