Are Red Currant/Josterberry flowers frost hardy

[Digeroo]

We have a heavy frost forecast but many of my fruit trees are in flower.  I know that plums suffer if the open flowers are frosted but can anyone tell me if the same happens to the currant family.  Gooseberries in flower as well.  Do I need to rush off and cover the bushes.

I really don't know...BUT..I've never covered my bushes..nor have I ever seen them being covered..not even in Finland (where late spring frosts are 'proper' frosts). I've never had any currants or gooseberries that would have failed produce a crop other than for disease, wrong timing with pruning or lack of water.
So I suspect they are not 'bothered' with frost. I'm certainly not covering mine..too late for it now anyway.

Many thanks for that.  Actually I have had a red currant in the garden which is an excellent fruiter and I have never worried about it, but it is sheltered from the worse of the wind by houses.  Things are a bit more raw on the allotment.

I lose plum crops to cold weather regularly, but I've never had any problems with currants.

Many thanks.

My red currants always fruit... irrespective but I have had some poor years with the Jostaberry... where I've only had too many fruit... rather than mountains..  :-X

I was given rooted josterberry two years ago but last year it only had four flowers and I am not sure what happened to the berries.  So I am very pleased that it is now covered in flowers.   I wanted to get to finally tasting them  ;D

Something else for me to look for ;D. Thank you Digeroo. There were berries on a white currant at a GC last week & they looked fine.

I always have a few spares...  :-X

Is that an offer David? ;D.
