Let us know how it goes. A photo of it covered in blooms in the summer would be good.
A scattering of a slow acting organic fertiliser such as Fish, Blood & Bone will be good.
Later in the season you may well find a new long shoot or two appearing from the base - train them towards the horizontal as well.
In a few years' time you can rejuvenate the plant by taking out the oldest stem or two - the newer ones will replace them.
