Mammillaria formosa chionocephala aka Mammillaria Riteriana

Mammillaria Riteriana does best in dry soil and should only be watered sparingly.

When it comes to the Mammillaria Riteriana, a potting soil that is too moist can cause problems. For this reason, it's important to use a soil mix that is well-draining and does not retain too much moisture. A soil that includes perlite or vermiculite for drainage and organic matter for nutrition is ideal. You can achieve this by simply adding a few scoops of perlite to your store-bought cactus soil.

Mammillaria Riteriana thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Mammillaria Riteriana.

During the wintertime, it's common for Mammillaria Riteriana to go dormant and their growth may slow down, so waterings should be spaced out more.

Ploi's records do not contain confirmed information on the toxicity of this particular plant. In the event of accidental ingestion of plant material with questionable toxicity by you, a family member, or a pet, it is always a good idea to consult a healthcare professional.

Mammillaria Riteriana enjoys dry environments, but misting the plant or providing extra humidity can create an environment for harmful fungi to thrive on the leaves.

The growth of Mammillaria Riteriana is not rapid and it doesn't necessitate any extra fertilization. By replacing its potting soil once a year, it should receive ample nutrition. It is important to note that plants obtain their energy from the sun's rays, not from fertilizers.

Mammillaria Riteriana’s native range is the Southwestern United States, Central America, and the Caribbean.
