Scotts was going through due diligence with Solus with a take over due before Easter, but, for as yet to be revealed reasons, the deal is off.
In a statment Solus said: "Solus Garden and Leisure has announced that, regretfully, it is no longer in negotiations to join forces with the Scotts Company (UK).
"The proposed deal, announced earlier this year, will now not go ahead."
Solus chief executive Mark Pearson said: "We are disappointed that our discussions with Scotts have not been fruitful but remain positive about the future of the company. The board and the shareholders are pursuing a number of other options for the business and we will communicate our plans in due course.’’
Managing director of Scotts Miracle-Gro Martin Breddy, said: "Our distribution agreement with Solus has expired. Stock is available via Decco, Stax or Scotts. Customers should contact a Scotts representative to agree new arrangements that suit them best."
He added: "Our single-minded focus is on delivering outstanding service to all our customers for the balance of the 2014 season."
The company has said that no further stock will be dispatched to Solus and no further growing media orders will be invoiced by Solus.
A Scotts representative said: "Most of our larger customers buy direct from Scotts and we already have great relationships with Decco and Stax, so there shouldn’t be any reduction in sales or supply delays.
Our team of group managers, regional sales managers, sales representatives and their supports will certainly ensure we supply all the stock that is needed."
Solus did not respond to requests for further comment.
