Visitors will find a floral spectacular with hundreds of colourful flowers, plants and arrangements along with everything anyone could ever want for a garden or allotment.
"Come and enjoy yourselves, forget about the election, put the long winter behind you, here the only mention of volcanic ash is likely to be a discussion about whether it will be good for the garden, " said Martin Fish, who has taken over as show director from Roger Brownbridge.
"We can offer the complete garden experience from tips on how to grow fruit and vegetable for beginners to information on rare plants from specialist growers and societies."
The North of England Horticultural society has already had one reason to celebrate the new gardening year with, Prince Charles becoming its first Royal Patron in 50 years.
"He is well known for his love of gardening and I am sure his association will only be good for the NEHS and the Harrogate flower shows, " said Mr Fish.
Increasing numbers of people want to grow their own fruit and vegetables and to cater for that demand for the first time the show will have Kitchen Garden Live, where experts such as Hilary Dodson, chair of the Northern Fruit Group and horticulturalist Joe Maiden will pass on their knowledge.
"We want to encourage people to grow their own whether its just in a pot or bucket or starting up an allotment, " he said.
The Daffodil Society's annual show, run by its northern group, could see one of its biggest entries for years with exhibitors staging as many as 1,000 blooms because of this year's late flowering.
But there may be fewer tulips, as growers have been willing their blooms to open in the recent sunshine in time for the Wakefield and North of England Tulip Society show.
"They are flowering very late compared with other years, " said chairman Malcolm Hainsworth. "We have our fingers crossed for the entries coming in."
However, the society will definitely be showing a beautiful arrangement illustrating the use of flowers, particularly tulips, in paintings.
The weather has also meant that some plants and flowers which are normally past by Harrogate will be on show this year.
"We have some early flowering primulas in our display that are normally finished in February, " said Sue Huntley, of Hartside Nursery Garden in Cumbria, "but we have had the hardest winter for 30 years."
Roger Proud of East of Eden Nurseries is unveiling a new range of Geums at the show while Bulldog Tools are celebrating 230 years of tool manufacturing with the world's largest spade on view.
Visitors are also being asked to bring along their own photographs for competitions which will be on display and judged at the end of the show – one called "vision of spring" for adults and another for children on "nature's beasties".
Another innovation is the appearance of a cookery theatre by the award-winning Fodder shop and café on the Showground where chefs will cook up treats using local produce.
The regional food group Deliciously Yorkshire is hosting a specialist food market with 25 producers including Botham's of Whitby showcasing a new ginger parkin.
AGAPANTHUS grower Steve Hickman hopes his floral display "Brassed Off" will hit the right note with the judges.
Mr Hickman, from Hoyland Plant Centre, in Barnsley, played the cornet for years in his local brass band so has a special feel for the subject of his entry in the innovative display competition, which this year is on the theme "It's Show time".
"I've played since I was a little lad and this combines both my interest in plants and music, " he said.
The double bass that his father played in the Hoyland Town Band is at the centre of the display, which is aptly sponsored by Strata Brass Band from Hoyland.
The display competition was introduced to allow nursery exhibitors the chance to be more adventurous while still featuring their flowers and plants.
