DIANTHUS

I planted 150 or so Dianthus in 30 pots at start of Summer. After they had finished flowering I cut them back. They have now begun to develop new foliage & some plants are showing new bud development & signs of re-flowering.

I am a novice where plants are concerned. I thought Dianthus were annuals & where thrown away after they had finished flowering?

Do Dianthus flower every year?

Can I overwinter these plants? If so; How do I do that? I do not have a greenhouse but a relatively frost-free car-port.

If overwintering; Do I water plants throughout winter?

Thanks

    Hi Billy

    That must have been quite a display over the summer!

    I'm not a dianthus expert, but have quite a few different varieties in the garden.
    They seem to re-appear every year, but tend to get quite straggly after a couple of years.

    When they get straggly, take cuttings (very easy) and you'll have fresh plants for the next few years.

    I wouldn't water over the winter months unless they get bone-dry. They prefer very well-drained soil and prolonged wet roots will rot them.
    As far as I know they're very hardy plants and don't need to be frost-free over winter.
    I leave my rooted cuttings in a corner of the patio over winter and plant out the following spring.

    Good luck!

  • Pete8 - Thank you for all the advice.

    Verdun - Sorry I wouldn't know how to post a picture I'm hopeless with computers. Anyway I don't think it would help. Plants mostly just green foliage. Bought from B&Q so no specific variety just labeled `Dianthus`.

    Thanks for replying anyway.
