Hi Ann, hopefully the member here will jump in and give you a link to a wonderful site to learn about these plants. I saw one yesterday at our most high end flower shop and it was full, I mean loaded w/ buds and a few had opened. I hesitated to buy it as they are known for dropping their buds when they are moved when budding out. I asked the guy there about my concern and he didn't convince me it wouldn't so I didn't buy it. It was $25.00 and that's a lot of money for a plant. Granted, it will bloom again, so it isn't a total loss. I still may go buy one if I don't see them anywhere any cheaper.

DON'T repot it now!I do know they like to be tight in the pot in order to bloom. Yours being a new plant should be ok in that pot for quite awhile, months even years. They also say no fertilizer while in the budding stage. My CC had blooms this past year, not knowing it as they were so tiny, I moved it AND fed it! All the buds dropped off. Easter/Spring cactus are identical to the other holiday C's. Treat it as you did your other one, and read the link if it is sent to you. Good luck. Welcome to the wonderful world of growing.

Easter/Spring cacti are treated the same at Xmas cacti except different times of the year.
Do not repot it until after it blooms and it's resting period.
