This festive plant is not only easy to care for and long-lasting, but it also has gorgeous blooms that will last through the winter. Learn more about how to care for your Christmas cactus and make sure it blooms with the right amount of light and water.

Caring for a Christmas Cactus: Tips for Maximum Blooms

Christmas cactus is a popular choice for many indoor gardeners due to its ability to thrive in low light conditions. Although it can withstand low lighting, the Christmas cactus will produce more blooms when exposed to brighter light. It is important, however, that you do not expose the plant to too much direct sunlight as this could burn its leaves and potentially damage the plant. Additionally, it is essential that you keep your Christmas cactus moist so that it can flourish.

The ideal amount of light for a Christmas cactus is 8 hours of indirect, bright light per day.

When it comes to temperatures, the Christmas cactus prefers a range between 55 and 65 degrees Fahrenheit.To trigger blooming, you need to provide your Christmas cactus with at least 13 hours of continuous darkness each day. This should start in late September or October and continued for eight weeks in order to ensure an abundant display of festive flowers during the winter holiday season.

When given the right care, a Christmas cactus can live up to 100 years. This makes it an ideal choice for those who want to enjoy its beauty for generations. With proper care, this festive plant will be a part of your holiday tradition for many years to come.

Finding the Right Light for a Christmas Cactus

When it comes to the best indoor light for a Christmas cactus, there is a place to put it. A bright east-facing window or bathroom can provide the perfect amount of indirect, bright light that your plant needs. Make sure to avoid placing your Christmas cactus in direct sunlight as this could burn the leaves and damage your plant. It is also important to note that too much sunlight can have an adverse effect on your Christmas cactus so be sure not to overexpose it.

If you don’t have access to a bright east-facing window or bathroom, then you may want to consider using fluorescent bulbs/tubes (or even compact bulbs) or led grow lights. It’s not recommended that you use mercury vapor or incandescent bulbs as these can be too harsh for cacti. A 75w grow light is usually enough to cover an area of around 5-10 square feet so if your space is larger than this, it may be worth investing in a more powerful option.

Generally, succulent and cacti need between 10 and 14 hours of light a day.

Caring for Christmas Cactus: Watering and Lighting Requirements

When it comes to watering your Christmas cactus, you should water every 2 to 3 weeks but only when the top third of the soil feels dry. If your plant is in 6 inches of soil, then you should water when the top 2 inches feel dry. You can check this by using your finger and inserting it into the soil near the base of your Christmas cactus. If it feels damp, then wait a few days before watering again. Over-watering or under-watering could lead to damage or death for your plant so make sure to keep an eye on moisture levels and adjust accordingly.

In addition to watering, you’ll also need to pay attention to the amount of light your cactus is receiving. Plants such as cacti and succulents can be successfully grown under 16 hours of fluorescent light mixed with incandescent light at a ratio of 10 watts of fluorescent to one watt of incandescent light. If you want flowers, then it’s best to study your plants’ individual requirements for lighting and adjust accordingly.

However, one thing to remember with cacti is that it’s never a good idea to spray them with water. Cacti have very low humidity needs and can easily be damaged or cause rot and other diseases if left on them.

So if you’re wondering how to tell if your cactus needs more light, there are a few signs you can look out for. The stem may be lighter in color than it was before, and its spine may be shorter or absent. An Opuntia (prickly pear cactus) will have an elongated, tubular or tongue-shaped pad as opposed to a flat, nearly round one. This is called etiolation and is caused by insufficient light.

When it comes to how long cacti can go without water, some species can go up to two years. However, this depends on the type of cactus and whether it is kept indoors or outdoors. Generally, indoor varieties need more frequent watering than outdoor plants.

An under-watered cactus can pucker, but can also be calloused and brown. If your cacti and succulents are showing these symptoms, it’s best to give them a thorough watering.

Caring for Christmas Cactus: Watering, Light, and Pot Size

Do you water Christmas cactus from top or bottom? It is recommended that Christmas cactus be watered from the bottom rather than from the top. With this method, you can be sure that your plant is getting enough water because it will soak into their roots and reach all of them. To do this, simply fill a bowl with about an inch of lukewarm water and place your potted plant in it for 10 to 15 minutes. This allows the soil to absorb as much moisture as possible without over-watering the plant. Once done, make sure to empty out any remaining standing water in order to prevent root rot or other diseases that could harm your Christmas cactus. Additionally, if you notice any leaves drooping down or turning yellow on your Christmas cactus then it’s best to reduce watering frequency until they recover.

Apart from watering your Christmas cactus, there is another important factor to consider when it comes to caring for them: how long do they need to be in the dark? In a cool, short day cycle, Christmas cacti produce flowers. To start the production of flower buds, there needs to be at least 16 hours of darkness and 8 hours of light each day. This means that during winter months – or whenever you want your plant to bloom – you should keep them in complete darkness for around 16 hours every night and then expose them to bright light for 8 hours during the day.

With the proper care and conditions for dormancy, christmas cactus can bloom up to two times per year.

Another important factor to consider when caring for Christmas cactus is the pot size. Do Christmas cactus like tight pots? It is recommended that you repot your Christmas cacti every 3 to 5 years, depending on how it’s doing. When repotting, try only going up a pot size as they like to grow in tight pots.

Growing Christmas Cactus in Shade

Can Christmas cactus grow in shade? Although the Christmas cactus does best in light shade, it is important to note that during the fall and winter months, full sunlight can be beneficial. During the growing season from April to September, ideal growth occurs at temperatures between 70 to 80 F. Too much sun exposure during this time could cause your plants leaves to look pale and yellow. On the other hand, too little sunlight could lead to fewer blooms or etiolation of your plant’s stem which would appear lighter than usual and have shorter spines.

If you choose to keep your Christmas cactus outside, it is best to place it in a shaded area such as under a tree or near a window.

To thicken your Christmas cactus, trim it about a month after it blooms, but don’t cut it after late spring. Pinching off one or more of the sections is another way to prune the plant and keep it growing in a bushier form. If you would like to grow new plants, replant them in separate pots.


Christmas cactus is an ideal way to bring some festive cheer into your home. To ensure your Christmas cactus is looking its best year-round, it is important to give it bright, indirect light, the right temperature, and 13 hours or more of continuous darkness each day. Additionally, you’ll want to keep it moist and make sure it isn’t exposed to too much sunlight. With the right care, your Christmas cactus will bring many years of joy and color to your home.
