Having recently gone through a name change (this plant was once called Cereus Tetragonus), Fairy Castle Cactus is still a popular houseplant for those who love desert plants. Its slow growth and compact size make it ideal to use in a window sill garden, or, it can be allowed to grow to its full height of six feet and used as a decorative garden feature.
How to Identify Fairy Castle Cactus
When you are trying to find this type of cactus, look for a cactus that grows tall, thin, and circular trunks. These trunks often grow in clusters. The trunks feature small spines running lengthwise from the top of the trunk down its side and to its base.

- Clean the seeds
- Allow the seeds to dry out
- Fill a plant container with a Succulent and Cactus Soil Mix
- Plant the seeds in the mix after they have dried
- Moisten the soil
- Keep the soil moist but not soggy and do not water the soil when it still feels wet
- Keep the plant container in a warm and sunny place
How to Propagate Fairy Castle Cactus
If you feel that growing one of these cacti from seeds is too time-consuming for you, don’t fear, there are other methods for propagating these plants. The best method is to propagate via cuttings.
Not only does this allow you to make new plants, but it will also allow you to keep the growth and look of your cactus under control. If you’re interested in using this method, follow these steps:
- Put on garden gloves to protect your hands from the small spikes on the cactus
- Clean a pair of scissors or another type of cutting utensil
- Cut off a healthy branch from a healthy plant
- Set the branch out for a few days to allow it to callus
- Fill a plant container with well-draining soil
- Dip the end of the branch in a rooting hormone
- Stich the branch into the soil
- Set the plant container in an area that is warm but not sunny
- Water the new plant a few days after it has been planted and water it only when its soil is dry
- Slowly acclimate the new plant to full sunlight
Fairy Castle Cactus Growing Conditions
This plant is ideal for anyone to grow in any part of the world as long as you know its key care requirements. Fairy Castle Cactus may be a hardy plant, but it does not tolerate cold and frost very well, so if you live in that sort of climate, you need to be prepared to grow this plant indoors.
Check the USDA Plant Hardiness Zone Map to find out which zone you live in and confirm whether or not you can plant this cactus in the ground or if you will need to bring it in during cold weather. It is very limited on where it can be planted (zones 10 and 11).
How to Plant Fairy Castle Cactus
While these are slow-growing plants, they will eventually outgrow the plant container they currently call home. When this happens, you will need to remove the plant from its container and replant it in a new and bigger container.
Here are a few tips for working through this process:
- always wear gloves
- Plan to repot your cactus during spring or summer to reduce shock
- Dust off the soil on the plant’s roots
- Inspect the plant for pests and remove them if necessary
- Prune the plant’s roots
- Do not water the plant right after it has been replanted but wait at least a week
Fairy Castle Cactus Potting & Soil
It is very important that cacti be set in soil that will drain off excess water. In combination with this, the plant container it is set in should also drain well. This is because cacti are highly susceptible to root rot from soggy soil.

Fairy Castle Cactus Water Requirements
As is the case with other types of desert plants, Fairy Castle Cactus should be watered very carefully. If you are uncertain about how and when to water a cactus or just want something to keep you on track with your watering regimen, consider getting a plant watering app .
To ensure that your Fairy Castle Cactus is properly and carefully watered, follow these guidelines:
- Only water the cactus if its soil is 50% dry from the top down (test it with your finger or a soil moisture meter )
- Do not spill water on the cactus since this can cause water damage
- Water the cactus in the soak and dry method
Fairy Castle Cactus Light Requirements
As a desert plant, it is assumed that Fairy Castle Cactus requires a lot of direct sunlight; however, this is not entirely true. This type of cactus can actually get sunburn if it is exposed to large amounts of direct sunlight for long periods of time.
To prevent sunburn and still give the plant adequate sunlight, set it in a place that gets six hours of morning sunlight. If this is not possible, set it in a place that gets filtered but bright sunlight.
If adequate sunlight is not available to you, especially in winter or extreme northern and southern climates, try setting your Fairy Castle Cactus under some grow lights.
Best Fairy Castle Cactus Fertilizer
Newly planted cacti do not need to be fertilized since their new soil should have plenty of nutrients in it.
When it does come time to fertilize your Fairy Castle Cactus, you will want a fertilizer that is specifically designed for cacti and something that can be diluted. Also, the plant will only need to be fertilized during spring and summer.
