Charlie and Adam Benton from Shepshed in Kent run Benton Bros Landscaping. They are seeing agents about a new series for 2014.
Charlie said: "We've met with an agent and hopefully there are a few channels that want to do TV shows with us. I want to do a bigger stand-alone show next spring."
The Gardeners Guild introduced the twins to ITV, which was looking for expert gardeners for a series of advice slots.
Charlie, who has worked with Outerspace Designs at the RHS Hampton Court Palace Flower Show, said the twins offer "something fresh".
He added: "When I see TV presenters putting a play frame in the garden that costs £10,000, who's got that? We're creating gardens from free materials because it's important to have a value-for-money budget. Were talking about how to do gardens in a way people understand."
