Dianthus grower Allwoods is moving back to its original site in West Sussex, having moved to Surrey in 2012.
The office and most of the mail-order plants have been relocated and the business is waiting for the completion of a 12,000sq ft multi-span polytunnel before it can finish the move. Allwoods hopes to open the retail area from 1 May and be fully up and running by the autumn.
It has also gained planning permission for a coffee shop and retail sales on the Summerfield Nursery site to widen the appeal to visitors coming to the nursery.
The business moved to Cheam Plant Centre on the southern edge of London in September 2012 and put its original site at the Summerfield Nursery in Hassocks up for sale.
Allwoods has been renting the site in Cheam with an agreement to purchase it when the sale of the Hassocks site went through, but interested buyers have struggled to raise the necessary finance, according to Allwoods office manager Emma James. The owners of the Cheam site were keen to sell and a buyer was found at the end of 2014, she added.
"Although to many this seems a backwards move, the reality of our return is we are now in a position to be able to offer more. The business can expand and grow as we have more growing room on this site," she said.
"We also have the added bonus of being more easily accessible from the main road, something sorely missed while in Cheam. This gives us the added benefit of being able to open all year round instead of just seasonally as we were in Cheam."
TV Publicity boost
Allwoods has seen "incredibly high returns" from the nursery being shown on the Great British Garden Revival in January and February, the owners have said. The nursery featured in episode three of the BBC2 series, which featured carnations and was presented by Christine Walkden.
