Lady Jane Percy, the Duchess of Northumberland, will be handing over control of Alnwick Garden as she moves onto new business-ventures.
Since it opened in 2001, the garden has created three hundred new jobs and helped fund many other charitable and educational projects.
The Duchess has now set a date to finish the garden and is in the final stages of designing a play area with German specialists, as well as lighting project 'Sparkle'.
"I have decided I am going to have finished the Alnwick Garden by May 2015.
The difficult thing is finding the right person to hand it to.
It will have been a big part of my life. I have to set a date to finish it."
