@Dovefromabove thanks Dove, Lemoinei looks lovely. Will give mine a feed and see what happens but quite frankly I am so fed up with waiting for it to do something every year I might try and replace it next year.
To be honest, if it’s only 2 years old does it need pruning? I have 3 philadelphus they are about 12 years old. As they are very established I prune after flowering.
First I take out ( cut off ) 1/3 of the oldest branches ( that shoot from the base of the plant ) to about 1 foot high, then I just lightly trim the remaining to improve the shape of the plant. That’s it, the branches will shoot at the base and refresh the bush with new grown. I didn’t even think about pruning them until they were about 8 years old.
