Mammillaria poselgeri aka Biznagita

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

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

When growing the Biznagita, it's important to use a potting soil that is well-draining and does not retain excessive moisture. An optimal soil mix should contain a high proportion of perlite or vermiculite for good drainage and some organic matter for nourishment. Simply add a few scoops of perlite to regular cactus soil to achieve this.

Biznagita requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Mammillaria Radleana is always in the right place to thrive.

Biznagita plants thrive in dry environments, however, if you choose to provide extra humidity or mist your plant, the lingering water on the leaves can create an ideal environment for certain types of harmful fungi.

The Biznagita grows at a slow pace and doesn't require any supplementary fertilizers. By renewing its potting soil once a year, it should receive enough nourishment. Remember, plants obtain their energy from sunlight, not fertilizers.

Ploi lacks confirmed information on the toxicity of this plant. If you, a relative, or your pet accidentally consume plant material with unknown toxicity, it's best to consult a medical expert.

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