Christmas cactus parents are advised to keep some factors in mind to stimulate and support their plant’s growth. 

Following are the nine factors that affect the growth of Christmas cactus:

  • Adaptability
  • Type of potting soil
  • Overfertilization of the Christmas cactus
  • Season for growth
  • Watering regime
  • Pruning
  • Temperature and humidity
  • Pests
  • The size of the pot


Adaptability means the time someone takes to adapt to a new environment. 

Whether human beings or plants, everyone takes time to adapt to new conditions. 

One can take more time than the other but will surely take some time to acclimate.

For example, A person traveling from a hot region to a cold region will take time to adapt to the cool climate.

Same way, when you move your plant, they also need some time and process to acclimate to the new environment. 

If you have bought a plant online, they will travel and go through some stages before reaching you, and they need some time to adapt to your environment.

The plant is already stressed, and if you do not take proper care, they will suffer from several problems such as yellowing, browning, wilting, etc. this is why such plants do not survive in most cases.

They need time and favorable conditions to adapt to the new environment and good air circulation. 

If you stress them with direct sun, repotting, or fertilizing, it will add to the stress and may cause loss of the plant.

Observe the plant’s state and let it be for some time. Water as per the requirement and provide indirect light.

Christmas cactus in their native environment grows without fertilizers, but indoors they need food due to limited conditions. 

They need food to grow, but overfeeding can cause more damage than good.

Pruning plays an important part in making plants taller and bigger. As the plant overgrows branches, they become heavy and may break off. 

If the pot is small, it cannot take the weight of the plant and may break or cannot support the plant’s growth further.

Pruning helps plants to grow better and also helps reduce the pressure on the roots and pot to support heavy items. 

Pruning will help but only when done at the right time of the year.

Christmas cactus bloom in the winter and should be pruned a month after the flowerings have ended, i.e., in the early spring. 

If you prune after that, the plant will stress out and can even stop growing.

Prune the plant by cutting stem segment joints from the top as much as possible. You can use the cuttings to grow more such plants. 

Suppose you find slow or no growth in your plant, then your plant might be root bound, which means the roots do not have enough space to grow any further.

Things to consider for pruning

Let us see what are the points to consider before pruning Christmas cactus:

  • Prune the Christmas cactus after a month of blooming.
  • Pruning during cold months can shock the plant and also affect its blooming.
  • Prune the joint sections from the top using scissors.
  • Use sterilized scissors to clip the stems.
  • Also, disinfect the tools after pruning to avoid any infection spreading to other plants.
  • If there are any damaged parts, dispose of them completely.
  • Repot the healthy parts of the plant.

Temperature and humidity

Christmas cacti are hardy cactuses that can survive various conditions, which can be variations in temperature levels or less humidity.

But this does not mean you can expose them or keep them in consistent unfavorable conditions. 

If you keep your Christmas cactus at freezing temperature levels for a long period, the plant can go into a permanent shock.

If you keep them under indirect light, the leaves will burn, and due to low humidity, the leaves and other parts will dehydrate. 

Keeping them away from vents and fireplaces in winters is very important. Also, make sure they are not exposed to cold or hot drafts.

They like average temperature levels and high humidity. If the condition is beyond their ideal conditions for too long, then the plant will suffer from several problems. 

Due to low light, they might suffer from yellow leaves and sunburn or wilting due to direct light.

Keep them at a temperature level between 75°F to 85°F. Move them to a safe spot when the conditions go beyond control.


Christmas cactus is a hardy plant and will fight diseases, but sometimes due to unfavorable conditions, they may fall prey to the irritating pests.

Pests such as spider mites, aphids, and mealybugs may infest your Christmas cactus, which will give a hard time to your plant.

This situation is usually due to overwatering the plant for a consistent period, high humid conditions attracting pests, the newly bought plant being already infested, or any other plant being contaminated with pests and diseases.

The plant will suffer from problems like yellow leaves, drooping, brown spots, holes in the leaves, vigor loss, etc. 

If you follow the plant condition, you may notice the signs in the initial stages. 

This will help you identify and treat the pest infestation faster while saving the plant from danger.

Isolate the infested plant, and use neem oil spray on the plant for several days to eliminate the pests. 

You can use chemical insecticides too for treating the plant.

If you use chemical pesticides, then follow the instructions and use only the right ones for your plant. Repeat using them till the problem persists.

It will take some time to recover, and with the right care, they will become healthier again. 

Do not fertilize or over the water till the plant is completely healthy.

Repot the plant when the roots have outgrown the pot and the pot is almost breaking. Also, make sure to repot them only during the growing season. 

Use a pot 1 inch bigger than before and not more than that. The pot should be 1 “bigger than the diameter of the plant’s root ball.

Make sure the pot has a proper drainage system and is porous.
