Aechmeas don’t have an extensive root system so most likely will never need to be repotted.
Aechmeas are easily propagated by the pups, or babies, which are produced off the mother plant. Here’s a big head’s up: the flower and stalk will eventually brown & die. Cut the stalk completely off.
You’ll see those pups will start to form off the base of the mother plant. The plant will slowly start to die (sad but true – it’s just part of its life cycle!).
You can just cut away the foliage of the mother plant after its completely dried and dead leaving the pups to form in that same pot. Or, you can remove the pups after they’ve reached 4-6″ & put them in a new pot. another option is to mount them on driftwood or bark.
Humidity / Temperature
Average on both is fine. Just know that Aechmeas prefer good air circulation. I grew Bromeliads in my Santa Barbara garden just a few blocks from the ocean so they got a fair amount of moisture from the air. If your home is really dry, then mist your Aechmea once a week. I grow my Bromeliads outdoors in the shade here in my Tucson garden so I up the ante with the water in those uber hot summer months.
