Taking Care Of Mammillaria Carmenae 

Ideal conditions

Mammillaria Carmenae likes filtered to full sun, doesn’t need much water, and needs warmer temperatures. With that said, this cactus is fairly frost-resistant, belonging to hardiness zones from 9b (25 to 30 degrees F/-3.9 to + -1.1 degrees C) to 11b (45 to 50 degrees F/7.2 to 10 degrees C).

Watering

The water needs of Mammillaria Carmenae aren’t much different than those of many other cacti. This cactus needs only occasional watering when the soil is dry to the touch. Fairly drought-resistant, the Mammillaria Carmenae cactus is difficult to underwater.

On the other hand, overwatering this plant is quite easy. This cactus requires little water in the first place, and too much water will lead to waterlogging and root rot.

In winter, keep the Mammillaria Carmenae cactus dry. It will be dormant, so it won’t be needing as much water as in warmer seasons, though you may occasionally mist it.

Where to plant

As soil, you should use a quick-draining cactus mix that won’t allow water to accumulate and harm the plant. For extra drainage, you may add some perlite in the mix as well.

If planting in a pot, make sure that the pot has drainage holes at the bottom to further encourage draining.

Mammillaria Carmenae doesn’t require as much light as some other cacti do – filtered but bright light will work just fine. It may also be exposed to full light, but definitely not on hot days.

Thanks to its not too high light needs, Mammillaria Carmenae can be relatively easily kept indoors. You just need to make sure that the pot with the cactus is placed in an area that’s well-lit by direct sunlight all day. But when it’s particularly hot, keep the cactus under a shade.

The Mammillaria Carmenae cactus can also be kept outdoors, but it should again be provided with protection from the scorching sun. 

In winter, outside cacti may need to be moved inside. But if kept dry, the Mammillaria Carmenae should do well in the temperature range of its hardiness zones.

General care information

Throughout the growing season, you should fertilize your Mammillaria Carmenae with a high-potassium cacti fertilizer. Begin fertilizing the cactus once you see new growth in the spring. The frequency of fertilization will depend on your fertilizer blend.

Don’t fertilize the cactus straight after repotting – allow the plant to settle in the new pot for about 2 months.

Speaking of repotting, it’s also a thing that you will need to occasionally do. Mainly, repotting is done when the cactus grows out of its pot, but it’s also done to just have a look at the roots and encourage growth by introducing the plant to new soil.

Try to repot the cactus every spring, or at the very rarest once every 2-3 years. After repotting, don’t water it for 1-2 weeks to allow it to recover from the stress of repotting.
