Top telly gardener Alan Titchmarsh has teamed up with Waitrose to bring out a new range of gardening products this spring.

Former Ground Force host Alan, who last year was announced as an ambassador for the upmarket supermarket chain, will help the retailer to boost its gardening offer.

The first products to go into stores this month include grow-your-own lines such as seed potatoes, onions and shallots.

Stores are also taking delivery of a seed range, as well as edibles such as strawberries, raspberries and rhubarb.

Waitrose manager for product development, Karen Thomas, said: “This launch means Alan will bring his expert knowledge and passion for gardening directly to our customers, beginning with a range of specialist varieties of fruit and vegetables.

“We know that our shoppers love cooking and gardening, and we’re pleased to be able to explore the possibilities of the kitchen garden further with some exciting new seed varieties,” Karen added.

Alan picked seed potato varieties (£2.50) that are “easy to grow with excellent flavour” to make up the range. Varieties include ‘Charlotte,’ ‘Desiree’ and ‘Maris Peer’.

Launching the fruit range, the former Gardeners’ World presenter said: “Fruit can be fitted into the smallest garden if you choose wisely.

“Crops are fresh and wonderfully tasty.”

His picks feature strawberry ‘Cambridge Favourite’ and rhubarb ‘Timperley Early’. Fruit plants cost £2.50.

Other key product launches include a new Bee Mat (£10) which comes ready-seeded with a mix of flowers designed to provide nectar and pollen for pollinators.

A Butterfly Mat (£10) is similar, but promises to attract a broad range of UK butterflies, providing them with the nectar they need during their mating season.
