I have a red currant in a pot that I've had for a few years. This is the second size up I've kept it in. I want to upgrade it again, but it grew buds earlier than usual this year. Can you repot a red currant when in bud? Or is it better not to?

I also got a new black currant that I wanted to put in a larger pot than it came in, but it's also in full flower right now. Safe to repot or wait? I don't want to lose all the blooms.

If you repot - the blooms are lost. I know that if I mess with a grape vine, it is worthless the rest of the year. I think it will be alright another year in its pot, and just plan on up potting next winter.
