Six outlets opened last year, taking the total to 32.
New sites in the pipeline include East Kilbride and York, as well as a joint store with Tesco in King’s Lynn in Norfolk.
Dobbies Garden Centres chief executive James Barnes said, "Despite a more challenging trading environment, investment in our business was our key focus last year – we invested in six new state-of-the-art centres throughout the UK and employed over 600 new members of staff.
"We have introduced more value lines into the business with our quality but value-driven "Essentials" brand which has gone down well with customers. We have also introduced a number of offers into our restaurants, allowing customers to enjoy Dobbies as a leisure destination."
