Meanwhile, Ball Colegrave has introduced the latest Trends Garden Decorators Guide, develped with Hortipak to help boost colour pot sales at retail.
Ball said: "The biggest trend that will affect garden centres is happening right now and is one of the greatest business opportunities our industry will experience for some time. With current government targets of over 200,000 homes to be built, the ‘Patio Garden’ boom is here.
"The typical home gardener visiting your garden centres is likely to be getting younger; they buy with their eyes, look for easy, fashionable and colourful garden solutions and are more typically cash rich, time poor.
"We want to make it easy for garden centres to capture these extra sales.
"The brochure sets out an easy, step-by-step guide on how to transform seasonal plant displays into a powerful selling area that home gardeners customers will love."
