Question

When several pups have grown together and are over 3 years old, can they be separated and replanted?

Answer 1

It actually is better to wait to separate until the pups are at least 1/3 the size the mother plant. Small pups don't divide well, but larger pups almost always survive.

You should make the divisions while the plants are actively growing, generally a warm part of the year.

After separating the pups leave them to sit on the counter for 24 hours before repotting. You can dust the roots with a fungicide.
Use a potting mix suitable for Bromeliads or an Orchid medium.
