How to Care for Astrophytum asterias Super Kabuto

If you are growing Astrophytum asterias Super Kabuto at home, then there are several things you should keep in mind in terms of caring for this cactus. You can go through these care criteria below.


Astrophytum asterias Super Kabuto cacti require plenty of sunlight. Thus, if you are growing them on your own, then you should ensure that they receive several hours of direct sunlight. Around six hours of this should be sufficient.

This can be easier if you are growing them outdoors. If you are growing them indoors, you can simply place the pot on a windowsill of your house that receives sufficient sunlight.

Ideally, this cactus should be kept in warm temperatures of over 21℃, although they can withstand colder temperatures as well up to a certain extent. In winters, if weather conditions get too cold, you can move them inside and place them on a window.

These cacti are known to grow in USDA zones 8 and 9.


You should water your Astrophytum asterias Super Kabuto cactus once a month during spring and summer (the growing season), although more than that might also be necessary if you live in extremely hot climates. Make sure you thoroughly water this plant so that the soil becomes well soaked.

However, make sure that you do not overwater this cactus as this could cause water to collect in the pot. This can then lead to root rot, affecting the health of the cactus as well.

You should let the soil dry up completely before you water the cactus again. During winters, you can water the cactus less often due to its dormancy.

Further, you should ensure that the atmosphere around this cactus is not too humid.

You should fertilize this cactus regularly during its growing season. You should ideally use a stable fertilizer that has a good balance of all nutrients. Make sure that you dilute this fertilizer with some water as it can otherwise prove to be too strong for the cactus.
