could be the weather , St Johnsworth can be cut back very hard now and will regrow no problem, Citrus should be indoors as it cant hack this weather, the Photinia it would be normal for it to shed some leaves but if it is the new growth if is caused by frost i assume, late next moonth give it a pruning and it should recover for next season. You dont say where you are but from thhe info supplied that would be the quiick answer, maybe post a photo so we can have a look a close up of the problem and one further back of the whole plant. |

mullingar, citrus is not right name spelled something like that, i say your right about frost on new growth, i wasnt going to prune anything too hard because i wanted these to be large back border plants, over 10 years, citisus correct name |

citisus or common broom does not like pruning, wait until the weather improves a bit before pruning, they will recover if you do not keep the photinia in check it will grow to a large tree and then wil need replacing if you want the new red growth each spring |
