Planted in the garden and been well watered, Leaves are started to droop and on closer inspection there are ants all over it!

I had this on a tree last year and it was Aphids got rid of them and the ants just went. If its not that - I read last week how ants hate the wet so if you can find their home and drench it?

Suggestions please on how to "kill" off ground ivy from fences. »
They don't, unless they made a nest inside the compost/rootball in the pot before you planted it. Or you've planted it smack on top of a nest.But check for aphid/scale infestation, that's usually why they're on plants, collecting the honeydew.
