The moon cactus (Gymnocalycium mihanovichii) is a type of cactus native to South America’s deserts in Brazil, Argentina, and Paraguay. A member of the Cactaceae family, this succulent plant is also known by the common names ruby ball cactus, star flowered cactus, and red cap. At maturity, the moon cactus is approximately one to two inches wide and has clusters of small, sharp spines.
As houseplants, moon cacti are typically mutants that do not produce chlorophyll, which is why they have such vivid colors—from hot pink to neon yellow. Due to this lack of chlorophyll, they must be grafter onto a rootstock cactus to survive. The moon cactus is most commonly grafted with Hylocereus undatus, but it can be combined with a green cactus of any species; Cereus peruvianus and Trichocereus spachianus are also common.
Dimensions of Potted Plants: L x B x H ~ 3" x 3" x 5"
Growth Medium: Coco Peat
Pot Description: Square Plastic Pot
How to Care for Moon Cactus Plants
With proper care, these succulents will bloom vibrant flowers in late spring or early summer.
- Provide the appropriate balance of light and shade. The rootstock cactus must receive enough sunlight for photosynthesis. Position your moon cactus near a window, but ensure that it only receives partial sunlight, as bright light can be damaging. If you decide to place your cactus on a windowsill, ensure that blinds protect it from receiving too much direct sunlight.
- Plant your moon cactus in well-draining soil. Overwatering a moon cactus can lead to root rot or mealybugs. Potting soil mix for cacti is acceptable for moon cacti, or you can add perlite or coarse sand to the soil for improved drainage. Choose a porous clay pot with drainage holes to help excess water drain.
- Water your moon cactus sparingly. Like many species of cacti, the moon cactus does not require large amounts of water. When watering, thoroughly soak the soil, then allow it to dry out completely. Do not water the plant again until the soil has remained dry for approximately one week. The moon cactus should only be watered in the growing season and not in the winter months.
- Place your moon cactus in a warm environment. Choose a location where the temperature does not dip below 60 degrees Fahrenheit. You can keep a moon cactus outdoors during the warmer months of the year, but move it indoors during the winter as frost is fatal to this cactus plant.

Q. What are the shipping charges?
We offer free shipping for orders above Rs. 499
Q. The plants received are in coco-peat. Do I need to repot them into regular soil?
Plants can comfortably grow in coco-peat if given feed at regular intervals. If you want to change the media we recommend maintaining the media near the roots and adding soil on the periphery.
Q. The plants I received are in a very small pot. Should I repot them?
We do not recommend repotting plants immediately after delivery as the plants have just travelled for some days before reaching you. You can repot your plant a couple of weeks after it settles in its new environment.

We deliver all over India.

Plants when packed well can be shipped around the world. We securely pack each plant with great care to make sure it reaches you in a healthy and happy condition. We only sell hardy plants online, and are confident that our plants will reach you feeling excited to be in a new home.
Q. Are these actual plant photographs?
All our photographs are owned by us and are of our own plants.
Q. My plant doesn't look like the one in the picture. Should I return it?
We try our best to give you a plant that looks like the one on our website. However, like us homo sapiens, each plant is unique and it's not possible for us display exact pictures for each plant.
Q. Do you offer same day delivery?
For Mumbai based orders, we can offer express hand delivery possibly at an additional delivery charge. Call us once you've placed your order for any such requests.
Q. How long do you take to deliver?

Q. Is it possible to change the pot of the plant in my order?
As long as the plant is a good fit for the pot, yes we can change the pot. Please add the plant and pot you want to order to your cart and in the order instructions page mention that you would like the plant to be repotted.
Q. I exactly followed the care guide given by you, but my plant doesn't look healthy. What should I do?
Our care guides are a simplified version of what you should follow given our tropical humid climate in Mumbai. However, even small changes in light, temperature, water, humidity, fertilization, and insect infestation can all have an impact on your plant. If you just received your plant, please give it some time - every plant takes time to adjust to a new environment.
Q. Are there any chemicals in our plants?
All our herbs are 100% organic. A few of our ornamental plants may have been chemically treated, but that doesn't mean you have to do that too. Most plants will be quite happy with some cow-poop and vermicompost.
