Can anyone help me get good cuttings of sunpatiens? I take the cuttings from healthy plants and rinse them thoroughly in tap water before rooting them in a weak fungicide solution. I then pot them on in warmth and high humidity (25 deg C /75%) as soon as roots form. They start well but after a week or two the leaves distort and they fail to thrive. I can keep them alive by continuing to use fungicide but few do well. - Ian.

I agree, the temperature is a bit high. All of them hate extra humidity (hence the serious problems of the last few years, commercially) so I think that you should try dropping the temp AND ensuring free air flow round the cuttings. I've just spoken to my supplier who grows them by the thousand or more and he immediately suggested the same.

Thank you for your advice and sorry it's taken me a while. I don't have a lot of choice about growing conditions as I can't change the Brazilian climate! I think I will have to get used to growing these as a WINTER plant!
I should have added - the ones I have in large pots 10-12" have done much better. I think this may be a plant that does not like tightly packed roots because they grow so fast. Also because I was watering them so much I made the mistake of putting saucers under the smaller pots. These impeded the drainage and may have caused the disease problem.
