Also planning to take part are Hozelock, Wyevale Nurseries, Pinetops Nurseries, Kerley & Co, Thrive, Myerscough College, Squires Garden Centres and USP creations.
The HTA is calling on members to contribute to next year’s display, called 40 Sunbury Road and celebrating HW columnist Peter Seabrook's 40 years at The Sun newspaper.
The theme of a back garden is thought to the first of its kind to feature in the Grand Pavilion.
Next year's creation will follow the success this May of the inaugural horticultural industry exhibit, called The Sunflower Square, which won a RHS Chelsea Flower Show Silver Gilt medal.
According to the HTA, 40 Sunbury Road - "a typical but modest suburban back garden" - will have living walls, a patio, decking, hanging baskets, containers, wildlife area, shed and greenhouse.
The containers and hanging baskets will include bedding and container plants grown by HTA members - garden centres, growers and seed trade.
There will be an area grown by schools that will include vegetables and wildlife-friendly plants. Westland Horticulture’s ‘Rising Stars’ will once again contribute the containers or baskets.
Trees and shrubs and other structural elements will come from HTA and APL members and garden product supplier members. More design details will be made available in the new year.
More than 100 companies contributed to the 2016 exhibit, with visitors including media mogul Rupert Murdoch with wife Jerry Hall and actors Jim Carter and Imelda Staunton.
