The Welsh shopfitter opened a new factory this month after a fire in 2013 destroyed work begun on the pods. It is now believed to be working on its largest order, which has doubled the size of the factory and increased its workforce to almost 40. The contract is though to be worth around £1m.
April 2013 saw the debut of the Waitrose flower garden range and Waitrosegarden.com, offering 6,000 gardening products in total.
The face of Waitrose gardening, Alan Titchmarsh, launched a range of grow your own and bee and butterfly products last week.
Bransford Webbs and Farplants are nursery stock suppliers. Scotts, Westland and Vitax are among the product suppliers.
Waitrose already claims two per cent of the garden market but aims for 10 per cent over the next two years. It plans to open 130 garden pods in 2014 in addition to the 40 opened in 2013, but would not comment further.
Butters is a major supplier for the retailer, with Crocus running its online offer.
