The new team has announced details of the Floral Awards for 2016 and beyond - replacing traditional judging methods.
The show will present the all-new BBC Gardeners' World Live Plant of the Year Award for the best new plant introduction at the show, the Geoff Hamilton Award for best exhibit in the Floral Marquee, the Best Display of Summer Plants Award and the Best Retail Area in the Floral Marquee.
A new Platinum Award has been introduced to give recognition to outstanding exhibits in the Floral Marquee, with Gold, Silver Merit, Silver, and Bronze Awards also available.
Bennett said: "It's so exciting to be working alongside such a great team and to introduce new exhibitor awards at BBC Gardeners' World Live. We look forward to working with River Street Events and the BBC to deliver one of the UK's biggest and most successful plant selling shows with high horticultural standards."
Nick Hamilton said: "To have an award in my father's name is a lovely acknowledgement of his legacy to the gardening public. Then to find it is to be awarded to the best exhibit in the Floral Marquee is the icing on a rather large slab of cake - he loved plants, and the Floral Marquee at BBC Gardeners' World Live was always his first port of call. I am very, very proud to be part of this award."
