I have a few Aechmea, some of which have developed 'pups' along side the main plant which seems to be still very healthy.
Is it safe to break them off and re-pot them now?
Hey Ian, yes you can break pups off at any time to re-pot, though the longer you leave them attached to the mother plant the better as they will be getting nutrients from that source.
Even when the mother plant starts to die off, you can still leave them attached as the nutrients from the rotting mother plant will feed the kids (pups).
