Carole Beesley said the garden centre and nursery will close in November with the owners retiring. There are 10 staff.
The six acre site is being sold for housing. She said: "That's where the value is I'm afraid, in the ground and not in the business. It will be a very sad day but we have no-one to take it on."
She said stock was gradually being sold off and there was interest in the fixtures and fittings.
Beesley's now only grows bedding. It formerly grew thousands of primroses in the winter but Beesley says Dutch imports killed that trade.
They have been operating their family-run business in Ravenstone, since 1952. The business was founded by Arthur 'Dusty' Beesley and his wife Betty. Their son, David and his wife Carole also work within the company.
Beesley's is well-known for creating the largest hanging basket in the Midlands. This spectacle was thought of by Dusty Beesley to mark the 50th anniversary of the business and has raised thousands of pounds for various charities.
Inspiration for this idea struck him upon his return from a trip to Ghent in Belgium, where the largest hanging basket in the world was on display. With the help of a local engineer, he constructed the basket frame which measures 15 feet in diameter and stands on a 35 feet pillar.
The basket is planted each summer, with bedding plants grown at the nursery. The basket contains approximately 1,500 plants and weighs 5 tonnes.
