Mammillaria carretii aka Mammillaria Saffordii Carrettii

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

The Mammillaria Saffordii Carrettii is very susceptible to soil that is too wet, so it's essential to choose a potting soil that drains well and does not retain excessive moisture. A soil mix that includes plenty of perlite or vermiculite for drainage and some organic matter for nutrition is ideal. You can easily create this type of soil by adding a few handfuls of perlite to regular cactus soil from the store.

Mammillaria Saffordii Carrettii 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 Saffordii Carrettii.

During the wintertime, it is common for Mammillaria Saffordii Carrettii plants to go dormant and their growth rate may slow down. Therefore, the amount of waterings should be spaced out more.
