Taking Care Of Notocactus Schlosseri

Ideal conditions

Notocactus Schlosseri does particularly best outdoors, mainly because it prefers partial to full sunlight. Indoor keeping is also possible, but only if you can provide it with direct sunlight all day.

Some Notocactus Schlosseri cacti do very well in low temperatures as well. These cacti can survive in temperatures down to 5 degrees Fahrenheit (-15 degrees Celsius), but only for a short time. While some Notocactus Schlosseri will survive low temperatures, keep in mind that this cactus thrives in warm temperatures and should be brought indoors in winter.


Water your Notocactus Schlosseri cactus only when its soil is dry to the touch. This cactus is drought-resistant and doesn’t require much water, and overwatering is very likely to cause root rot.

In winter, suspend watering the Notocactus Schlosseri cactus. Dormant in winter, the cactus requires little to no water to survive, and it also gets more sensitive to overwatering than in summer. Cacti kept dry are more cold-resistant as well.

Where to plant

To ensure adequate drainage, Notocactus Schlosseri should be planted in a cactus potting mix that drains fast. For extra drainage, add mineral grit such as perlite or coarse sand in an around 1:1 ratio.

If the cactus will be potted, pick a pot that has large drainage holes at the bottom so that water is allowed to escape.

Given that Notocactus Schlosseri requires partial to full sun, you should keep it outdoors if possible – this is where sunlight is abundant, and you will have many more spots to choose from where the cactus will get adequate sunlight.

If outdoor growing isn’t an option for you, then you can grow Notocactus Schlosseri indoors as well. However, for best growth, the cactus should be placed in a spot that is directly lit by sunlight all day. If direct sunlight is lacking indoors, you may compensate for it with growth lights, but remember that natural light is preferable.

In winter, you should move your Notocactus Schlosseri cactus indoors. Though this cactus can be highly resistant to frost, it will not survive long-term exposure to low temperatures, and the temperature resistance of Notocactus Schlosseri may differ from cactus to cactus.

General care information

Apart from the above, you will also need to fertilize and occasionally repot your Notocactus Schlosseri cactus. 

Fertilization should be done during spring and summer once every month or two, depending on the strength of your cactus fertilizer. Usually, cacti fertilizers are diluted to half strength before feeding.

As for repotting, do it in spring or summer once you notice that the cactus has outgrown its pot, which may happen every other year or two, depending on the size of the pot. With that said, keep in mind that annual repotting is preferable since it allows you to check out root health and introduce the cactus to fresh soil.
