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.
1. Prioritize Growth
June is all about helping your Christmas cactus put on healthy new growth. If you're wondering how to grow a Christmas cactus that flowers reliably year after year, this is the stage you shouldn't overlook. Unlike desert cacti, these plants are native to tropical forests, so they prefer conditions that are a little more humid and forgiving. I find the easiest approach is to water thoroughly when the top layer of soil feels dry rather than following a rigid schedule.
This is also the ideal time to fertilize a Christmas cactus. During its active growing period, a balanced houseplant fertilizer every few weeks throughout summer can help support stronger stems, healthier foliage, and ultimately a better display of blooms later in the year. I use the TPS Christmas cactus fertilizer from Amazon to help mine thrive at this time of year.
It may not be the most exciting gardening task, but in my experience, taking the time to fertilize a Christmas cactus regularly is one of the simplest ways to encourage a healthier plant and a more impressive flush of flowers come winter.
2. Give It Plenty of Light
Another mistake I see time and time again is people keeping their Christmas cactus in a dark corner. While you may have heard advice to keep a Christmas cactus in the dark to encourage flowering, that only applies later in the year when the plant is beginning to set buds. During June and the active growing season, plenty of bright, indirect light is essential for healthy growth.
A spot near a bright window is usually ideal. If you have outdoor space, you can even move the plant outside for summer, provided it's sheltered from intense midday sun and protected from sudden temperature drops. In my experience, the extra light often encourages stronger growth, which ultimately sets the plant up for a much better flowering display in winter.
I've found that one of the easiest ways to make sure a Christmas cactus gets enough light is to raise it slightly off the floor. The IKEA LÅNGNÄBB plant stand is my go-to for this, as it positions the plant closer to the window without taking up valuable sill space. I'm also a fan of adjustable plant stands like this Amazon option, which let you tweak the height throughout the year as light levels change.
3. Think Ahead to Winter Blooms
It's easy to focus on what's blooming right now, but when it comes to Christmas cacti, a little forward planning goes a long way. Everything the plant does over the next few months is helping it prepare for the flowering season. In fact, many common Christmas cactus mistakes – such as insufficient light, inconsistent watering, or neglecting to feed the plant during summer – can reduce the number of blooms you see later in the year.
If you're wondering how to make a Christmas cactus bloom, the answer often comes down to the care it receives long before buds begin to form. The stronger and healthier your plant becomes throughout summer, the better your chances of enjoying a spectacular display of flowers when winter finally arrives.

Personally, I've found that the best-performing Christmas cacti are rarely the ones that receive complicated care. They're the plants that get the basics right: enough light, consistent watering, occasional feeding, and a little attention during their active growing period.
So if you've been neglecting your Christmas cactus because December feels a long way off, consider this your reminder. June may not be the month when the flowers appear, but it is the month that helps make them happen. A few small adjustments now can pay off with a much more impressive display when winter finally arrives.
