Any plant needs sunlight and water for it to survive.
It is the primary source as to how they can thrive and will be the determinant of the plant’s health as they grow.
Think of it as a human. It is the equivalent of food and water for us.
One of the interesting types of plant you can care for is the Christmas cactus.
It’s rare as it is not commonly seen in a flower shop daily, but once the season comes, it can fill almost all shops.
Plus, it is easy to take care of and propagate as long as done correctly.
To help you, here are the Christmas cactus light requirements that you can use as a guide.
Let’s get started!
Getting to know Christmas Light Cactus
Christmas Cactus, with its scientific name Schlumbergera truncate, is a plant under the family of Cactaceae.
Although it uses the name cactus, the way it looks and is taken care of is different from the regular desert cactus.
Its physical appearance can be described as having flat stems and a flower with a striking resemblance to a cerise flower, often located around Northern Hemisphere.
It is also popularly known as Thanksgiving cactus, crab cactus, or holiday cactus, but the Christmas cactus is the most well-known.
The plant earned the name for itself due to its blooming season, which is at the same time as Christmas.
Thus, it becomes a perfect gift during the holidays.
How Much Light Does My Christmas Cactus Need?
Now, if you are planning to get one for yourself, you must remember that just like any other plant, it needs to be taken care of.
Your Christmas cactus can propagate within a month if you’ve done the right job.
Here’s a trick to know when dealing with it.
To successfully propagate it, it both needs light and temperature.
As mentioned above, this plant is similar to other types of plants that need to have light to survive.
Now for it to have flowers, it has a specific light requirement.
On a cycle of 8 days, it should have a light of 8 hours each day and be kept in the dark for 16 hours.
No matter where you placed your Christmas cactus, make sure that when it is a dark time, it should be dark.
No light should be introduced to the plant.
If this happens, the blooming cycle will be destroyed, leading to the plant having difficulty flowering.
Direct light vs Indirect light
As you have learned, the Christmas cactus needs a specific set of lights to survive.
Here, you will know the difference between direct and indirect light.
Light can only be considered as direct light when the light rays from the source directly hit the plants without any covering or filter.
On the other hand, indirect light is somehow the light that hits the plants with a medium or a filter.
It can be a shade, a leaf, or other materials that slow down the direct hit of the light.
Now, there is another type of light that some plants need. It is called a partial shade.
In simple terms, it refers to a type of plant that needs direct sunlight for a specific time and then becomes shaded for the rest of the day.
For example, some plants need at least 3 – 6 hours of light. Some areas can have this type of condition where during the morning, light comes visible and only sunny during that time but not the rest of the day.
Is Direct Light for Christmas Cactus?
It will be discussed here about its sources, benefits, and works to learn more about direct light. For starters, the main source of direct light is the sun.
So plants that are outside receiving direct light energy from it are considered plants that use direct light.
Take note, it can be sunny outdoors but considered indirect light.
The critical component as to how light is considered direct is when the rays from the source directly hit the plants.
For its benefits, sunlight is the optimal light perfect for growing plants as the wavelengths in there cannot be replicated by artificial light.
Furthermore, it’s eco-friendly since it’s renewable energy and cost-efficient.
Now, for the important question, is direct light applicable to Christmas cactus? The answer is NO. Direct light is harmful to this type of plant.
Direct light cannot be controlled, and once it hits the leaves or the flowers, it can burn and destroy them. So avoid using this at all costs.
Indirect light: A lighting source for Christmas Cactus
On the contrary, as mentioned above, indirect lights are those lights received by plants with the help of a medium.
There are a lot of sources where you can get it.
To name a few, these are sunlight, which passes through medium, moonlight, and LED Lights.
Indirect Lights have their fair share of benefits like adjustments and control for the strength of light energy plants receive, especially if plants need indirect light; cost-efficient as you may use the lights outside and inside the house as a source provided that it has a medium it can bounce of and perfect if you are creating indoor gardens.
This is the perfect type of light for Christmas Cactus to consider.
They are inclined to survive using indirect light but make sure that it’s bright enough for them to receive the needed energy.
Christmas cactus: light exposure and its amount?
If you remember, the vital key for a Christmas Cactus to survive is temperature and sunlight.
As you now know, Christmas Cactus needs indirect but bright light.
No specific energy of measurement, but the cycle mentioned beforehand should be followed.
For its temperature, it’s best if they are in a humid condition.
Learn to know the balance as exposing your plant to direct light can cause damage, and lack can cause difficulty growing.
Can a Christmas cactus live in a dark room?
Yes, and No. Christmas cactus needs at least 8 hours of indirect light and 16 hours of dark. It is ok for them to be placed in dark-shaded places provided that the lighting conditions are still met. Putting them in the dark without access to light is not advisable.
Choosing the Best spot for Christmas cactus at Home
Your Christmas Cactus can be put outside and inside the house provided that the conditions of light and temperature are met.
For outside spots, it can be placed in the garden or on the porch, provided it is shaded and not hit by direct sunlight.
Now, the best place you can have them is inside. Specifically, you can place them near the window, kitchen, or bathroom.
Just make sure that they receive indirect lights from these spaces.

If this happens, you need to help fix it by doing some of this.

- If indirect outdoor light is not enough (as the plant is placed near a window), you can reinforce it with indirect LED light.
