It may feel a little odd to be thinking about Christmas while summer is getting into full swing, but if you own a Christmas cactus, June is actually a key month. In my experience, this is where a lot of people go wrong. The plant looks healthy, it's putting on new growth, and it seems happy enough, so it gets left to its own devices. But the care you give it now plays a huge role in how well it flowers later in the year.
One of the biggest myths surrounding Christmas cactus care is that they only need attention once buds start appearing in autumn. The reality is that winter blooms are months in the making. Right now, your plant is focused on growing, storing energy, and building the strength it needs to produce those signature festive flowers when the holiday season rolls around.
