the leaves all turned brown and dropped at the bottom now she's very long what do i do to make her bushy again and how do i propagate it if someone can help me i'd be thankful omni
Zebra plants tend towards legginess, unfortunatelly. Regularly pruning the plant back and then repotting the cuttings with a bit of root hormone might do the trick.
Difficult to tell from the photo how much light your plant receives but try moving it directly in front of a south-facing window. Zebras high light plants.
Zebras can be difficult for some to keep indoors where it's dry, especially during winter. They like lots of light and humidity, more of a greenhouse type setting.
