What to Do With a Christmas Cactus in July for a Show-Stopping Christmas Bloom Display
Simple July care tips to help your Christmas cactus thrive now and deliver a spectacular festive bloom later in the year
Christmas cacti aren't just festive houseplants. With the right year-round care, they can thrive for decades – even more than 100 years – rewarding you with healthy summer growth and vibrant winter blooms.
Often dismissed as a seasonal decoration, a Christmas cactus (Schlumbergera) is actually a long-lived, easy-going houseplant that earns its place in your home all year round. This guide to Christmas cactus care covers the essentials, while what to do with a Christmas cactus in July focuses on the key midsummer tasks that support strong, healthy growth.
July is one of the most important months in its growing calendar. While flowers are still months away, your Christmas cactus is actively producing the healthy new stem segments that will support this year's display. The care you give it now – from watering and feeding to light and pest checks – lays the foundation for vigorous summer growth and abundant winter blooms.
If you're looking to add one to your collection, the Christmas Cactus from Plant Addicts is a beautiful, established plant that's ready to thrive with the right care. It's already made its way into my shopping cart.
1. Water Consistently, but Let the Compost Dry Slightly First
Christmas cacti appreciate more moisture than desert cacti, but they still dislike sitting in wet compost. During July, warmer temperatures usually mean they need watering a little more often, especially if they’re growing in a bright spot. Before you water a Christmas cactus, check that the top inch of compost feels dry – tools like the Xlux Soil Moisture Meter from Amazon can take the guesswork out of timing.
If you find it tricky to keep up during peak summer heat, Iridescent Self-Watering Globes offer a simple, stylish way to maintain steady moisture levels while helping to avoid overwatering.
When you water, do so thoroughly, allowing any excess to drain away completely. Never leave the pot sitting in water, as prolonged soggy conditions can quickly lead to root rot. In particularly warm homes, the plant may dry out faster than expected, so it’s best to respond to the compost rather than stick to a fixed schedule.
2. Feed During Active Growth
July falls within your Christmas cactus’s active growing season, making it a good time to fertilize a Christmas cactus. A balanced liquid houseplant fertilizer applied every two to four weeks provides the nutrients needed for healthy stem development – products such as TPS Christmas Cactus Fertilizer from Amazon are specially designed for this stage of growth. For a lighter, more convenient option between feeds, Gardenera Professional Succulent Spray Fertilizer Mist can also be used to gently support healthy growth.
Avoid overfeeding, however, as too much fertilizer can encourage weak, leggy growth rather than strong, compact plants. Stop feeding toward the end of summer, before the plant begins preparing for its flowering period.
3. Give It Bright, Indirect Light
Light levels are at their strongest in July, so now is a good opportunity to check whether your Christmas cactus is receiving the right amount. A bright room with filtered light is ideal – place a Christmas cactus a few feet back from a sunny window if needed to soften the intensity.
Too little light, or keeping a Christmas cactus in the dark, can slow growth significantly, while intense afternoon sunshine may scorch the flattened stems, leaving them bleached or reddish.
If your plant has been sitting on a south-facing windowsill, consider moving it slightly back from the glass or using a sheer curtain to diffuse the light during the hottest part of the day.
4. Move It Outdoors if Conditions Are Right
Many gardeners successfully move their Christmas cactus outdoors for the summer, where higher humidity and better air circulation can encourage vigorous growth. If you choose to place a Christmas cactus outside, select a sheltered position in dappled shade, protected from strong winds and direct midday sun. Morning sunshine is generally fine, but harsh afternoon rays can scorch the flattened stems and damage the foliage.
Before moving a Christmas cactus outdoors, wait until nighttime temperatures stay consistently above 55°F (13°C). Once outside, continue checking the compost regularly, as pots tend to dry out more quickly than they do indoors, especially in warm or breezy conditions.
5. Check Regularly for Summer Pests
Warm weather can bring unwanted visitors, particularly if your Christmas cactus spends time outdoors. Christmas cactus pests such as mealybugs, scale insects, and spider mites can quickly take hold in summer conditions, so inspect the stems every week. Pay particular attention to the joints between stem segments, where pests often hide.
If you notice an infestation, isolate the plant and remove insects with a cotton swab dipped in rubbing alcohol, or treat more widespread issues with a horticultural spray such as Bonide Captain Jack's Neem Oil. Catching problems early helps prevent damage and keeps the plant strong ahead of the flowering season.
6. Propagate Healthy Stem Segments
July isn't usually the time for heavy pruning, but it is an excellent month to propagate a Christmas cactus. Healthy stem segments root readily in warm temperatures. Simply twist off a section containing two or three stem segments, allow it to callus for 24 hours, then insert it into a free-draining cactus or succulent potting mix.
Keep the compost lightly moist while roots develop. Not only is propagation an easy way to expand your collection, but removing a few healthy segments can also encourage a fuller, bushier plant over time.
