Consultant Neville Stein said: "It wouldn't surprise me that Wyevale would want to buy Notcutts - after all, buying an 18 strong chain of garden centres is a quick way to expand their portfolio of stores.
"It seemed at one time Notcutts were keen on acquiring new stores yet there has been little activity from them in recent years - maybe they have been outbid by other buyers?
"I suppose the question is whether Notcutts is for sale, that I don't know but would not be surprised if they were. With no Notcutt family members - as I understand it - directly involved in the daily operation of the company, one might wonder what the future holds for the organisation."
Wyevale Garden Centres said: "We do not comment on rumours or speculation."
Notcutts did not respond to requests for comment.
