Watering frequency

As usual the most significant thing you need to practice in terms of watering the pencil cactus is watering them only when their soil is dry.

Consider that you are someone who lives in hot and dry weather conditions, then you need to water them once every two week maximum.

On the other hand, if the weather conditions get cooler, you could cut down on watering and reduce watering to once every month.

Always keep in mind to avoid over watering these cactus, unless there could be severe repercussions. 

It could cause root rots of the plant and hence it could be fatal on the plant unless you do not remedy it immediately.

To reiterate, please bear in mind to first check whether the soil is dry and only then resume watering them.

If you think the soil is still moist, wait for another couple of more days and resume watering them.

In addition to the aforesaid, it is vital that you grow them in a pot which has enough draining holes so that the excess water could move through the draining holes without retaining in the pot.

On another note, ensure that you do not over saturate it too. If in case you spot your pencil cactus has become wrinkles and shriveled, you may assume that it lacks water.

As such you need to water them thoroughly whilst letting the water soak through the soil well.

Preferred Light condition

In terms of providing adequate sunlight for indoor grown pencil cactus, keep in mind that they still require plenty of sunlight to thrive.

What I would suggest you do is to locate the cactus near a bright and sunny window so that they could absorb the essential sunlight level.

Low light conditions would not suit the pencil cactus as they cannot survive in those conditions. 

Having said that, they could still manage to stay alive if you water them on a constant basis. Further you need to keep them in an environment where the temperature is at a healthy level for them to thrive.

One more tactic you could practice when you are growing the pencil cactus indoors is rotating your cactus once every month.

Consequently, that will allow the entire plant to expose for light evenly. This will further avoid any potential etiolation of the cactus too.

Correct pot 

Choosing a correct pot is crucial when you are growing the pencil cactus indoors as that would have a direct impact on the plant’s prosperity and on its well being as well. 

As you may already understand, the pot you chose to grow them should comprise excellent drainage.

Moreover, your cactus should be able to fit in conveniently in the pot too. They  could sometimes form long roots.

As such, the best is to use a deeper pot. When you provide a deep pot, it would help the cactus to grow better and vigorously and healthily too.

When it comes to selecting the right material for the pencil cactus, it should ideally be ceramic or glazed terracotta pots. 

The reason behind using them is that they are porous, and it could avoid the water retaining in the pot too.  

What is concerning about using these pots is that they are not light weight when you fill them with soil along with plants.

So just a piece of advice from me! Make sure you have located the pot in its final position before you plant the cactus and add the soil.

In case, if you think you might have to shift the cactus here and there, best is to use plastic or resin containers.

Obviously due to the light weight, you could shift them conveniently. Although you have this option, it would not be that helpful for the cactus to thrive well.

That is because they are poor insulators particularly during extreme temperatures. It would not be healthy for your cactus roots as well.

Chances are that the water could get heated in summer times when you grow them in such pots.

You could still fix this if you water them often. Moreover, you could paint the pots in white also Apart from that you could even wrap them also with aluminum foil.

Soil condition

Just like the succulents and with cactus, the soil mix you are using should be a well-draining one. Be it indoor growing or outdoor growing.

Moreover they would prefer to have dry and sandy soil to thrive well too.   Further you may consider adding perlite also as that could enhance the draining of the soil.

If I suggest to you a right potting medium for these cacti to thrive well, it could ideally be a mix of two parts of cactus mix and one part of perlite.

Fertilizer 

Pencil cactus do not depend on fertilizers a lot and they have quite modest requirements when it comes to fertilizers.

Usually, they tend to grow in poor soil, and they could adapt to any kind of growing conditions as well.

However, although they do not depend on a lot of fertilizers, you could consider feeding them which would be beneficial to enrich their nutritional level.

If you want to feed them,  you may utilize a diluted houseplant fertilizer once a year during the spring season.

Having said that, please be mindful that you do not overfeed them as it could badly affect the cactus’ wellbeing and on their health as well. 

It would have severe repercussions such as what you encounter with over watering

. You could grow the pencil cactus well if you provide them with bright light, sandy soil and water them on and off as appropriate.

You may use a balanced liquid houseplant fertilizer to feed them during spring season

Consider that you have a mature and a well grown plant, then you could use a 20-20-20 houseplant food at quarter strength.

You may further use a controlled release fertilizer to feed them. If not, instead of that you may use a fertilizer which has a low nitrogen level.

Pencil cactus would also tend to become larger in size as they grow. As such you would want to repot them ideally in a slightly bigger pot so that they could thrive well.

It is an easy process you could follow to transplant them. Before proceeding with anything, make sure you are wearing eye protection, long sleeves, long pants, and gloves which could cover up to your wrist.

One more important thing to note is that you need to ensure the soil medium is dry before you take off the plant from the older pot.

After that you could select a pot which has enough draining holes and which is made out of a good material as explained above.

Next you may place the plants in a naval pot and fill in the potting medium. You may arrange a potting medium as aforesaid.
