Taking Care Of Mammillaria Zeilmanniana “Pink Crown”
Mammillaria Zeilmanniana “Pink Crown” is best to grow outdoors – this is where it’s the easiest to take of its high sunlight demands (partial to full sunlight).
In terms of temperatures, the Pink Crown cactus definitely shouldn’t be exposed to low temperatures, even though it can survive in temperatures down to 25 degrees Fahrenheit (-3.9 degrees Celsius) for a short time if kept dry.
The water needs of Mammillaria Zeilmanniana “Pink Crown” are pretty low – you need to only water it when its soil is dry. Like many other cacti, the Pink Crown is drought-resistant and doesn’t need much water.
Keep in mind that you should not allow water to accumulate near the roots of this cactus. Overwatering is very likely to cause waterlogging and root rot in this cactus. You should only water the Pink Crown just enough to make its soil moist.
In winter, suspend watering this cactus. Dormant, Mammillaria Zeilmanniana “Pink Crown” will require very little water to survive. If the cactus is outdoors in winter, then keeping it dry will allow you to prevent freezing or root loss. But remember that long-term exposure to cold is dangerous for the Pink Crown cactus, so bringing it inside is a better option.
Where to plant
To make sure that water does not accumulate near the roots of your Pink Crown cactus, plant it in a fast-draining cactus potting mix. For extra drainage, you may add mineral grit like coarse sand or perlite to the mix as well. A 1:3 ratio of mineral grit to potting mix seems to work adequately for this cactus, though you may add more mineral grit if necessary.
If you are intending to keep your Pink Crown cactus in a pot, then make sure to choose a pot with large drainage holes at the bottom so that the water has a way to escape.
Due to its high sunlight needs, Mammillaria Zeilmanniana “Pink Crown” will do best outdoors. This cactus loves full sunlight all day, and a lack of light can negatively affect its growth and flowering.
You can still grow this cactus indoors, but only if you have the right spot for it. A window sill lit by direct sun all day would be the best option.
No matter where you are keeping this cactus, make sure to temporarily move it to a shaded location on very hot days.
General care information
During spring and summer, fertilizer your Mammillaria Zeilmanniana “Pink Crown” with a cactus fertilizer. Depending on the strength of the fertilizer, you should fertilize your cactus from several times a month to once every two months.
Repotting is also a thing that you will need to do, either every spring or after the cactus has outgrown its current pot. Annual repotting is preferable since it allows you to inspect the roots of the plant, as well as introduce the cactus to fresh soil.
