My blue rain has got a pup but the mother has not died, it is still in flower what do I do
Pups can appear at any time Anita and they will feed off the mother plant as it dies. The mother will eventually die after flowering but it can take quite a long time, so just leave it as it is and let it do its thing.
If the pup gets a fair bit bigger then it will be able to be broken off and re-potted, though its always best to let it stay with the mother until it is fully rotted down.
