It got very little water during the winter.
the conservatory is frost free-little heater with thermostat sees to
that.( we live in Northern Ireland) I only water it when it is practically
dry. could be that it needs repotting. Is there any way I can use tap water
e.g leave it to sit so that some of the lime evaporates ?

have used insecticides, fungicides and given it a dose of Sequestrene
all to
no avail. I also gave it a foliar feed.
As it is a lime hater I have been watering it with water from a
barrel-could
this be the problem ?

How often have you watered it? And did you water it through the winter?
And are the roots free-draining? Is the Conservatory frost free? And if
not, where do you live?
To be honest, I think it might be trying to survive this onslaught of TLC
on
your part. Was it infected with a fungus, did you see any insects on it?
We are particularly concerned that you've given it far too much water,
feed
etc.

I don't know that leaving water to 'sit' causes lime to evaporate so can't
help you there. If you really think the water is the problem, try giving it
mineral water for a few months! But I don't know that Mandevilla is *that*
fussy about its water. If the nursery from which you bought it is a
friendly and helpful one, then it might be worth taking the plant back to
them and asking their opinion/advice. Certainly, in your shoes, that's what
I would do. But in the meantime, I wouldn't give it any more 'treatment' of
any sort, other than to water it when it's really dry, let it drain freely
and so on. Feeding a sick plant is thought not to be a good idea, in any
case. But do try having a chat with the Nursery.
