Tender perennials Sanjy......usually treated as annuals.
Over or under watering seems to be the most common cause of plants suffering; poor compost though, esp fhe rubbishy mpc that everyone uses, also is a big reason for it.
I have a large abutilon in the garden trained against a wall and it benefits from extra watering now and then. I realise not everywhere but down here it has been a pretty warm, at times hot, summer
