I have a four year old rhododendron which is in a large pot in acid compost. This year it has four flower buds on every terminal, which is a record for this plant, but unfortunately it is drooping it's leaves (not through lack of water I assure you) the leaves are not floppy but quite firm and mid green. It has never had dark leaves, I think it is Mrs Lewinsky. Pink with a maroon splash in the centre. Can you tell me if this is likely to be an attack of vine weevil and if so what to do about it?
Many thanks (sorry to re-post this query, but I'm a novice Rhodo grower and need the advice)
