I'm a beginner gardener and need help with a Camellia (I think I have the 'lemon drop' which has a gorgeous layered white flower). The tree was here when I moved in and is planted in a sunny spot (but not very sheltered). It's producing a lot of blooms but as soon as they open (sometimes even before) they go yellow and die. Someone told me that they need acidic soil and that this is what the problem is - so I just bought some Sequestrene plant tonic for it. Is there something else I can do to the soil to make it more acidic and do you think this is what's wrong with it? Help much appreciated!
