I am loving this forum so far - everyone is so knowledgeable! I was wondering if I could throw another quesiton at you all, this time about a 3 year old Rhododendron Madame Masson. (photo below).
I bought this 3 years ago, planted it in ericaceous compost in my garden and pretty much just left it alone. I guess I needed to have given it more attention over the years, because it looks pretty bad now with holes in most of the leaves. And this year it just isn't flowering even though it seems to have flower buds everywhere.
Does anyone have any advice on how to save this plant? Are the holes from slugs? And should I remove the flower buds if they don't flower?
