- Watering: Mist your plant frequently while it is blooming to keep the soil uniformly moist.
- Light: For moderate light and some direct sun, place the cactus in an east-facing window.
- Fertilize every two weeks once buds have formed with a high-potassium fertilizer.
How often should you water a flowering Christmas cactus?
- Water every two to three weeks, but only until the top one-third of the soil feels dry to the touch. Water when the top 2 inches of soil feel dry, for example, if the plant is in 6 inches of soil. (Check with your finger!)
- Soak the soil until water runs through the drainage holes in the pot when it is suitably dry. To catch the water, place a tray underneath the pot. Remove any extra water from the tray after 10-15 minutes so that the pot does not sit in water.
- Feed every two weeks with a balanced houseplant fertilizer from spring through early fall. Feed the cactus once a month in the fall and winter to encourage blooming.
- Late in the spring, prune plants to encourage branching and more flowers. Simply cut a few portions off each stem, and the plant will branch out from the wound.
- Place the cut pieces in a gently wet potting soil if desired; they will root easily after a few weeks and make great Christmas gifts!
How to Get Your Christmas Cactus to Bloom
The lower temperatures and longer evenings of autumn bring out the blooms of Christmas cacti and its relatives. This is the general blooming schedule for the three main species of Christmas cacti:
- Thanksgiving cactus are the earliest and most persistent bloomers, blooming from late October to mid-winter.
It’s possible that your cactus isn’t flowering because it’s getting too much sunshine or being exposed to too hot temperatures. Here are some pointers to help you get yours to bloom!
- For at least six weeks, nights must be at least 14 hours long and days must be between 8 and 10 hours. If you have powerful interior lighting that is turned on at night, you may need to cover your cactus or transfer it to a location where it can be exposed to natural light.
- Flower buds form best when the plant is kept between 50 and 60 degrees Fahrenheit (10 and 15 degrees Celsius).
- By exposing the plant to temperatures of around 45°F (7°C) for several nights in a row, you can jumpstart the budding process.
- Ensure that you water the plant on a regular basis when it is in bloom. If the plant dries out too much, the buds may fall off.
- Don’t worry if the cactus loses its buds throughout the winter; it will bloom the next year!
Should I fertilize my Christmas cactus while it is blooming?
- Summer: Find a shady spot outside. While the plant is actively growing, keep it hydrated and fertilized. Stop fertilizer application towards the end of the summer to enhance flowering.
- Fall: Bring your plants inside before the first frost. Keep the soil as dry as possible. In September or early October, begin the above-mentioned budding regimen.
- In the winter, place the plant where it will receive four to six hours of indirect sunshine. Keep the soil moist and the air from becoming too dry.
Should I water a blooming cactus?
Water is required for active growth, including blooms. Most cactuses in their natural habitat receive the majority of their annual water during the summer monsoon rains. Never use automatic irrigation on a cactus or water it during wet periods. Only water your cactus if natural rainfall isn’t enough to keep it looking well. Always consider the temperature, humidity, and weather prediction. By hand, inspect the soil and err on the side of caution. Between waterings, let the soil to totally dry. This prevents root rot, crown rot, and fungal illnesses caused by insufficient watering.
How often should you water a flowering cactus?
Another conundrum you could be facing is how often you should water your cactus plants.
Because, as previously stated, several factors influence the plants’ watering requirements, you won’t be able to set a fixed watering schedule. Indoor cactus plants, for example, require less watering than outdoor cactus plants due to their varied growing conditions.
Another consideration is the age of the plant. Younger cactus plants are more demanding and require more frequent irrigation to keep growing. Because they are actively growing, these plants require more watering in the spring and summer than in the winter.
During the spring, summer, and autumn months, cactus plants should be watered every 7 to 10 days for best growth. During the winter, when the plant is resting or dormant, increase the time between watering sessions (approximately every 4 to 6 weeks).
Should I water my Christmas cactus from the top or bottom?
Remember that Christmas cactus plants demand moist soil rather than the dry dirt preferred by most other succulents. When the top inch or two of soil on a Christmas cactus is dry, water it. Fill the pot saucer with stones and water to just below the tops of the pebbles (the pot should not be sitting directly in water) to assist improve the humidity around your plant. As the water evaporates, the air will become more humid. (See below for watering suggestions if you’re attempting to get your Christmas cactus to rebloom.)
How can you tell if a Christmas cactus is overwatered?
Although sagging, limp leaves and stems that are mushy at the bottom are strong indicators of overwatering and root rot, the only way to know for sure is to examine the plant’s roots.
Should I mist my Christmas cactus?
Christmas cacti, contrary to popular belief, may live much beyond the month of December. With a little TLC and some advise from us, they can live for up to 20 years.
Christmas Cacti need cooler temperatures.
If you keep your Christmas cacti in a room that’s between 60 and 70 degrees Fahrenheit, they’ll bloom more and faster. It’s especially vital to keep them away from radiators, fires, and warm windowsills in the winter.
While they don’t need the heat of the sun, they do need its light.
This is when things get a little complicated. The sun will dry up a Christmas cactus if it is left in direct sunlight, although it does require lots of sunlight. So, what should a cactus aficionado do? Leave it in a somewhat shaded location of your house (or outside once summer arrives) and rotate it every now and then.
Just like you and I, Christmas cacti need their rest.
If the buds on your cactus haven’t set yet, it will require 1215 hours of complete darkness per day. Cacti flourish in bright light only once their buds have set.
You should be misting, not watering, every day.
Your cactus will die if it is overwatered. That isn’t to suggest they don’t become thirsty. You should mist your cactus every day instead of watering it like you would a typical plant. All you need is a few squirts from a spray bottle to keep your cactus happy. Watering the plant’s base should only be done when the soil is absolutely dry to the touch.
Christmas cacti need nutrient-rich soil.
Christmas cactus are resilient plants that may thrive in a variety of soils, but they need well-drained, somewhat organic matter-rich soil. While you can always buy organic soil, you may also use your cacti as a little compost and add organic materials that would otherwise be discarded.
Is coffee grounds good for Christmas cactus?
Your Christmas cactus will appreciate a cup of coffee just as much as you! Coffee grounds are high in potassium and nitrogen, which the cactus requires to stay healthy. You should not use the grounds right away since damp grounds can mold, so spread them out to dry first.
Should you deadhead Christmas cactus?
Deadheading cactus flowers can promote additional blooms and encourage growth while also tidying up the cactus. While not necessary for all cacti because some cactus flowers drop from the plant once they are spent, deadheading cactus flowers can promote additional blooms and encourage growth while also tidying up the cactus. While the Christmas cactus is in bloom, deadheading can be done at any time during the growing season.
