MD Matthew Bent is forecasting a 5% rise in revenues for the 12 months to January 31, up from £13.5m last year.
He expects profits to remain at about the same as last year because of rising food costs.
He said takings up by more than 20% in the second two weeks of March with roses, plants and gifts selling well for Mother's Day.
Bent said people who planned 'staycations' and royal wedding parties were buying garden furniture.
Bents has spent £100,000 on extending its nursery and hopes to win planning permissin for the second phase of a £9m expansion programme.
