Choose the Correct soil

It is essential that you grow the pencil cactus in sandy soil which is well draining as that would help them to grow healthy as well as vigorously.

I would recommend a cactus soil mix as the best growing medium to grow pencil cactus. The special characteristic when it comes to cactus soil mix is that they do not retain excess moisture.

You could add perlite in the growing medium as that will be beneficial to fasten the draining of the medium and that will help them to thrive.

In addition to that, you could grow pencil cactus in rocky infertile soil mix as those conditions would suit them best.

You could use them for rock gardens whilst using other succulents as well. Alternatively, you could grow them in container gardens in your yards as well.

You may use a mix of cactus soil mix and perlite as a good potting mix to grow the pencil cactus in pots.

You could add the cactus soil and perlite at a ratio of 2:1. More importantly, it is vital that the potting medium you use should be a porous one which would help for better drainage.

The quality of Potting medium is not something which you should mainly be concerned about.

What is essential is only to have a potting medium which is well draining, and which does not store any excess moisture.

Provide Suitable Temperature

Pencil cactus would perform well in a temperature range of 50°F to 70°F (10°C – 21°C). Having said that, they could also withstand light frost too.

They could thrive in temperatures in 30°F and above too. On the other hand, they could survive in temperatures such as 100°C.

Consider that you are living in a location where your plant will be exposed to regular frost, then it is up to you to protect your cactus from intense colder weather conditions.

To do that you may use frost cloths. Instead of that you could even let them grow in mini greenhouses as well. 

You could let the pencil cactus grow outdoors during autumn and in winter so that you could spot their stunning foliage in red.

Adequate Humidity

You may provide them with dry and arid weather conditions for the pencil cactus to thrive well.

What you need to ensure is that you provide them a good aeration and that would help the plant to survive well.

Once you cut the pencil cactus leaves, you would see how they form a milky sap. That would be toxic and would cause allergies in your skin as well as in your eyes. Hence make sure that you do not get in contact with the sap.

To briefly explain on how to proceed with pruning,

  1. First, wear your protective gear such as gloves, goggles etc. That will protect you from the irritating sap they produce when you cut them.
  2. Start taking off the dead stems. Make sure you are using sterilized pruning shears to do this.
  3. Proceed with pruning the branches from above and that would help to reduce the height of the cactus and further it will help to stimulate the bushy growth as well.
  4. When you cut them, you could spray some water on the edges and that will avoid the sap forming out.
  5. Best is to dispose of all cuttings in a secured place or even burn them unless you do not use them to propagate them.
  6. Clean the tools you used and disinfect them as well.
