impatiens walleriana

Hi all,

Nice to see we are all back to normal with the forum open!

I have recently bought some impatients walleriana seeds H1 but after reading about them there is lots to say about downy mildew.

Is this disease still a problem (I have read it could have been due to a certain batch of seeds)? Not sure whether to try these seeds, or just throw them and start with the new guinea.

    I don't live in Britain, but I heard the worst of downy mildew has passed and the nurseries have begun to grow busy lizzies once again. I have lots of mildew in my garden when the climate changes (with either a sharp drop or rise in temperatures), and the way to deal with it is a rigorous control of umidity. Since busy lizzies are mainly grown in shade or half-shade, it is a bit more difficult to control watering because the soil does not dry too easily, but you can always add grit and raise the beds a bit, these will probably help.

    I have never had trouble when I’ve sown them from seed, only when I bought plug plants.
