Nearly every white daffodil in my garden has been picked or cut by something... humans have been ruled out, the stalk is cut at the base with no chew marks, no part has been eaten... is this the work of a dog, slugs or something else? Thanks!

I now think my Prunus serrulata 'Kiku-shidare-zakura has canker, as there is a gummy ooze on some branches. Do I cut them out now or wait until June?

I am growing a hedge with mixed Portuguese Laurel and Photinia, and haven't touched them for the first couple of years to let them get established. They are slow growing and most of the Photinia are bare on the lower parts and there's a few tall ones with growth at the top and bare branches. To make them thicken out, should I be pruning back to ground level? When should I do this?

The attached photo is of my 20 year old Prunus serrulata 'Kiku-shidare-zakura' growing outside my kitchen window. I trim it every summer to keep it compact as my garden is small. I'm tempted to remove the side branch as that is now getting quite heavy. What is your advice.
