Garden Centre Group (GCG), formerly known as Wyevale, is due to be put up for sale by its main lender Lloyds Banking Group next month.

PwC is understood to be looking to kick start the sale of Britain’s biggest garden centre specialist in July, when sales for its 119 sites are traditionally strongest, according to The Mail on Sunday.

GCG is understood to have been in talks with Lloyds Banking Group about refinancing the company’s debt, ahead of its debt facilities expiring in early 2012.

The retailer was founded in Hereford in 1962 by Harry Williamson and now employs 4,500 workers.

It was acquired in 2006 for £445m by a group led by retail entrepreneur Sir Tom Hunter. In 2008, it passed to Bank of Scotland in a debt-for-equity swap after it failed to manage its £419m loan payments.
