HART went into administration late in 2005 (HW, 2 March 2006), owing nurseries and trade suppliers around £500,000.
Director Jessica Adams took control of the company in 2005 and added the finance backing of the Barwell Group in March 2006. Barwell has now pulled out.
The company, which claims that 140 garden centres use it, will continue to supply deals from Scotts, Sinclair, Sankey, Wolf Tools and other companies.
HART founder Eimert de Graaff and operations manager Paul Lewis have left.
Dutch company PRS is now set to source and supply plants to garden centres.
