Gooseberry leaves turning brown purple [Solved]

Is this bad? At first I thought it might just be a gooseberry thing as I've never grown them before but when they started going brown I started getting a tad worried.

It's still growing well with fresh growth however. It is currently in a pot in my coldframe.

Ta!

 

Goosegogs are very hardy, so I doubt the temperature has done it. I think its more likely that they are starving, or in particular, missing some vital nutrient. I could be wrong though.

I agree temperature as well , apart from that doing great

 

Thank you, I left them outside overnight twice in a row recently by mistake. I guess it must be that. Can I leave them outside in a few weeks time do you think?

 

do what we do with annuals out during the day in at night for two weeks or cover with fleece overnight

 

All mine are making fruits already. No foliage left though thanks to the caterpillars!

 

I'm still not sure it's a temperature thing ....mine are doing fine

 

Loli are your inside the greenhouse or out Nfrost are in

sawfly caterpillars

 

Which rapidly moved on to the nearby Polygonatum!!

 

Sounds about right I also had a silver birch tree that was 12 feet tall striped in 48 hours not a bird to be seen !! do birds eat them or not ?

 

Mine are outside,I personally wouldn't keep them in a GH or coldframe

 

I think the sly gits eat the leaves from the underside. If that's the case the birds will only see them once all the leaves are gone!

 

My old head gardener could never pronounce Polygonatum, always said Polyognums.
