Andrew Porwol, who owns and is director of Sapcote Garden Centre bought Sharnford Garden Centre and Nursery, a six minute drive away in Sapcote, Leicestershire.
Former owner Stephen Banks, who has left Britain, sold his 0.4 hectare site with growing area, 400sqm of glass and 2,000sqm of tunnels. Turnover was around the £200,000 mark.
Sapcote employs 50 staff, has a seven-figure turnover and also covers 0.4 hectares. Porwol aims to employ a further 50 staff at Sharnford, which will be a "work in progress for the next 12 months".
He said: "Sharnford was mainly wholesale but we want it to be retail. I want both sites smoothly integrated so they benefit each other to avoid the danger of them both competing.
"The deal completed two months ago and the site was closed and in need of a bit of care when we took it over," said Porwol, who did not disclose how much he paid for the business.
He replaced rotting wooden benches with new aluminium ones from Holland, block paved several areas and reduced steep level changes. He aims to recover the tunnels this summer.
"In its day Sharnford had a reputation for growing summer bedding and we will get the nursery up and running in summer. We will continue with bedding but add shrubs, perennials and roses.
"Sapcote, which opens a new coffee shop in two weeks' time, doesn't have the space to grow. The market, however, has moved on in the last three years and the economics favour more growing."
Estate agent Alexander Mackie Associates handled the property.
