Hi, this is on behalf of my mum who has had four shrubs die in a particular area of her garden in the last few months. Her neighbour lost a shrub in the same place (but over the fence). One was a lilac but she can’t recall what the other ones were. Below is a pic of one of the dead ones. She is wondering what is causing this die-off, there are other shrubs around the dead ones that aren’t dying and seem to be doing well. She is wondering if they have just died of old age or if there is something weird happening with the soil in that spot. Any ideas? Thank you.
