If you have not already repotted, I suggest you not unless you absolutely have to. Zebras need to be potbound to set
flower buds in late summer, early fall. If you can tolerate watering frequently, leaving it in its small pot will be your best bet for
flowers this year.
The
plant started wilting after you put it outdoors? It may be that the sun was too hot. Zebras like some sun indoors where the sun isn't as strong. If it doesn't perk up after watering, the wilting might be caused by something else, such as root rot.
All,
I love Zebra
