The Manchester-based non-food cash and carry launched its first gardening catalogue in 2009 and now has seven specialist gardening sales staff. It is now offering delivery to all garden centres for the first time.
Stax, which joined the HTA in 2009, has seven gardening sales representatives and four sites across England — in Leeds, Manchester, Birmingham and Bristol.
It has a 30 per cent bigger gardening catalogue for 2010, a new online ordering system and a new SupaGarden range for the independent garden centre.
Operations director Nigel Wright said: "Since we expanded our operations within the delivered wholesale garden sector, the demand has been phenomenal.
"Retailers are conscious that we carry a massive product range from all the major brands and our big buying power means our customers constantly get the best deals."
