overwintering tender plants

I have brought indoors some tender plants including Coleus, Delosperma, Heuchera and Kalanchoe.
I am wondering if such plants plants need any watering over winter?

    Coleus definitely will.  Heuchera may die down completely, keep just damp. Delosperma and Kalanchoe keep on the dryish side, unless you have them in a very warm , bright place, in which case keep watering.

    Heucheras are totally hardy - they don't need protection Des  :)
    I don't know anything about the others as I don't grow them, but most plants require little watering over winter, especially those like drier conditions anyway  :)

  • Heucheras are tough Hardy perennials leave them outside. Coleus drink gallons even in winter I wait until mine start to flag then plunge them in a bowl of water until  they can take up anymore. The other two keep on the dry side I only offer water every 3-4 weeks again I stand them in a bowl let they take up what they want and then drain them. Don't let them have water sitting in the bottom  of their containers.

    That's interesting re the coleus, tessa and fidget. I grow none of those plants so wouldn't really have a clue about them.
    Are coleus not annual plants - or do you overwinter them for next year somewhere warm?

  • Coleus is a funny one most varieties are described  as tender perennials  so in the garden, as bedding,most people treat them as annuals.  But they can be grown as houseplants  and you can take cuttings from your garden ones before dumping them and overwinter the cuttings to start your display next year.  I use them as houseplants  just keeping an eye out for mealy bugs etc which love them.

    I would cut the coleus hard back, putting the offcuts in water where they will develop roots and you can then pot them up and grow them on for new plants the following year.

    The original 'mother plant' will grow new shoots and leaves, but the leaves in the second and following years are never as big and gorgeous as in the first year IME ... that's why it's good to propagate new plants.

    If you don't cut the mother plant back it'll react to the lower light levels in the winter by growing long, straggly and pale.
