Garden centres bought and sold over the past 10 years total 250, say the three biggest specialist agents.
Last month, HW reported that 40 Garden Centre Association centres have been bought by groups over the past decade.
Recent big acquisitions include six Garden Stores by Hillview Group, seven Garden & Leisure outlets by The Garden Centre Group and independents by Notcutts, Squire's, Blue Diamond and QD Stores.
Gilbert Evans director Mike Gilbert lists around 70 centres sold over the past decade, including 16 in the last year. Quinton Edwards lists around 80 in the past 10 years. Among the biggest are Peter Barrett and Sanders to Wyevale.
Director Simon Quinton Smith said: "Consolidation will continue to increase. More big garden centres are being sold than there are middle-sized garden centres becoming big. But there will always be independents because there will always be small independents (that chains do not want) and large independents who have family who want to take them over. Most people don't want to sell if they don't have to. If they have family who can take them on, they're happy."
Alexander Mackie says it has sold more than 100 centres over the past decade but could not provide the data.
Last month, HW found that garden centre consolidation is accelerating, with more than 25 per cent of leading independents bought by groups since 2005.
Rate of acquisitions
Comparing the 2005 Garden Centre Association membership directory with 2014's, more than a quarter of centres listed have been bought by groups including The Garden Centre Group, Dobbies, Notcutts, Squire's, Klondyke, Blue Diamond and Hillview.
