They will keep on the garden centre's 14 staff.
The Hammond brothers have granted a 15-year lease to Home & Garden.
Nine other businesses occupying rented facilities on the multi-use retail site and employing around 40 people will be unaffected. Home and Garden plan to open a ‘Blossom Cafe’ similar to those they have at five of their other garden centres.
Other businesses on the Leighton site include an aquatics centre, beauticians, dog groomers, a pet shop, car wash, crafts centre, hot tub and pool suppliers and installers, a conservatory company and a children’s nursery.
