My gardenia is four years old and has been doing really well , flowering beautifully and looking great.
however over the last couple of months he has detiorated massively and although budding, the buds are dieing and he's generally looking poor
I repotted him last year as he was too big for his old pot and he seemed fine after that, I gave him a cut back a couple of days ago to get rid of dead sprouts but not sure if there's anything else which might help....
any suggesions much appreciated....
