Last year, Dutch show Plantarium took place in the final week of August, one week before Four Oaks and IoG Saltex, with Eastgro following the week after.
Show organiser Sue Last said: "After carrying out a review of the show's activities, from both the visitors' and exhibitors' perspective, it became apparent that an earlier date could be more beneficial as September's show calendar is very busy."
The Eastgro show will take place on Wednesday 5 August this year.
Last believes the early August date will give garden centre buyers "a purposeful sales focus so they can re-stock for autumn, and landscapers can plan for the upcoming planting season".
John Woods Nurseries will be the new host for the show this year at its site in Pettistree, Suffolk.
The company will be putting on tours of its production facilities.
