Bizzy Lizzies dying and white on leaves

Help please! I only put my bizzy lizzies out into tubs a few days ago (they have been in the conservatory since they were plugs). They have started to shrivel up and die. Wome of the leaves have white on them. Any suggestions please.

 

Cover them up with something like single sheets of newspaper for a few days to protect them from hot sun sun and wind. A few sticks pushed though will keep the paper in place. Plus well water early/late.

I've found it best to gradually acclimatise them to the aggressive elements outdoors before planting them out.

 

I think you're looking at weather damage, Maidmarion.
You can't just take plants that have been living indoors and stick them outdoors. Hardening off is about a 10 day process.
You might save your plants by taking them indoors at night, or covering them with fleece, until they get used to things. It's not all about temperature. It's about plants getting used to the wind blowing in their faces etc.
They might stagger a bit but hopefully will recover. Good luck.

 

It does sound like wind burn, Impatiens are prone to scorch due to the thinness of the leaves. As Alice says, they should recover.

 

I got my sunpatiens a week ago from a company and when they arrived they look good but 5 have died and only was apack of 10.

Mine are still in greenhouse too cold to put out yet.

And still to make room in raised bed for them

 

Thank you for all your posts. Very useful tips and I will know next time.
