Watch: How can a brand make the most of the 'money-can't-buy' Chelsea Flower Show?

Melissa Littler, marketing and PR director at BrandAlley, argues that the RHS Chelsea Flower Show is a great opportunity for online-only retailers to come face-to-face with their customers by hosting them at such a prestigious event.

BrandAlley, which has been awarded a bronze prize for its Italian Renaissance-inspired design, also invites brands it works with to the garden in the evenings for a networking event that is a "money-can't-buy experience".

This year's RHS Chelsea Flower show is proving one of the most popular yet due to the return of Alan Titchmarsh, who has a garden at the show for the first time in almost 30 years.
