Taking Care Of Gymnocalycium Mihanovichii ‘Hibotan’ “Moon Cactus”

Ideal conditions

The Gymnocalycium Mihanovichii ‘Hibotan’ “Moon Cactus” likes filtered to full sun and temperatures on the warmer side. Belonging to the USDA hardiness zone 10a, the Moon Cactus does well in temperatures no lower than 30 degrees Fahrenheit or -1.1 degrees Celsius.

Watering

Among cacti species, the water needs of the Moon Cactus are unremarkable – they are the same as with many other cactuses. That is, the Moon Cactus should be watered only when its soil is dry to the touch. 

Do not overwater this plant since standing water will likely cause nasty issues like root rot. The Moon Cactus is drought-resistant as any other succulent, so it’s easier to overwater than underwater it.

In the winter, watering should be suspended. The Moon Cactus is dormant in winter and thus needs little to no water. Due to this, it’s much easier to overwater cacti in the winter and cause root rot.

After the winter has passed, steadily increase the water supply to the typical levels.

Where to plant

The Moon Cactus should be planted in a well-draining cacti mix. This is important to ensure that no water accumulates in the soil, leading to root rot. You may also add some perlite to the soil to increase its draining ability.

Whether or not to plant the Moon Cactus indoors or outdoors depends on your preferences. Due to the relatively low light needs of this cactus, it is equally easy to keep indoors and outdoors.

The Moon Cactus likes full to filtered light, so you may keep it under direct sunlight, but do place a shade over it during the hottest portion of the day. Direct summer sun at the hottest time of the day is likely to cause sunburn.

Outdoor planting may be a good option for some people as well. However, if winters in your area are cold, you will need to move the plant inside. Remember that the Moon Cactus isn’t a frost-hardy species of cacti.

General care information

Other than the care steps described above, you should also fertilize the Moon Cactus during its growing season (spring and summer) and repot it every once in a while.

Repotting is usually done in spring after the dormant period every year. This is to encourage the growth of the cactus by introducing it to nutrient-rich soil.

Aside from that, you would want to repot your Moon Cactus if it has grown too large for its current pot.

No matter whether your cactus has overgrown its pot, you may want to repot it every spring. Aside from potential benefits coming from new nutritious soil, this would allow you to have a look at the roots, check their condition, and remove any damaged parts of the roots if you spot any.
