A few months ago I bought a Christmas cactus (Zygocactus) on special. I put it in a pot with some orchid mix and have watered as needed.
It looks like it's getting ready to flower, as I have multiple buds appearing.
Should I consider giving it some form of fertiliser before it flowers? If so what type of fertiliser would I use.
Zygocactus need minimal fertilising. Maybe something very gentle in Spring, but definitely not at the moment. Also, don’t move the plant now that buds are forming - they hate changes.
Zygocactus flower at this time of year because its initiated by the longer nights. So make sure the plant isn't exposed to light overnight - even household lighting will affect them. Cover with a box if you need to.
