The nursery became a subsidiary company of Roundstone on 1 February, after the grower went into administration.
Former New Forest Plants general manager and director Matthew Dixon, who took on the role of nursery manager of the site after the Roundstone deal, said the business was winning back the customers it had lost.
"We held on to the smaller retailers we supplied, but lost quite a few of the larger customers," he said. "They are now coming back and we are getting a lot of orders."
He said Roundstone had been supportive. "We are a smaller nursery at the other end of the scale, producing a huge variety of plants in small volumes. Roundstone is very keen to grow the brand."
The nursery grows a large range of herbs, alpines and herbaceous perennials. It also produces wild flowers and soft fruit.
Dixon added that the business could benefit from the closure of rival grower RA Meredith & Son (Blooms), which went into liquidation this month.
