Mammillaria herrerae aka Golf's Ball Cactus

Golf's Ball Cactus does best in dry soil and should only be watered sparingly.

To ensure the health of your Golf's Ball Cactus, it's crucial to use a potting soil that won't hold too much moisture. A soil that drains well and contains perlite or vermiculite for drainage and organic matter for nutrition is ideal. Adding a few handfuls of perlite to store-bought cactus soil is an easy way to create this type of soil mix.

Golf's Ball Cactus 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 Golf's Ball Cactus.

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

The toxicity level of this plant has not been officially confirmed by Ploi. If there is a possibility of ingestion of plant material with an uncertain toxicity by you, a family member, or a pet, it is advisable to seek the assistance of a medical professional.

Golf's Ball Cactus prefers dry environments, so misting the plant to provide extra humidity and allow water to linger on the leaves can create an ideal environment for fungi that can be harmful.
