Taking Care Of Mammillaria Marksiana

Ideal conditions

The ideal conditions for Mammillaria Marksiana are typical for a succulent – this cactus loves full sun, requires very little water, and does best in warm temperatures. Mammillaria Marksiana is a little frost-hardy (down to 25 degrees F/-3.9 degrees C), but it shouldn’t be exposed to low temperatures for long.


Water your Mammillaria Marksiana cactus like other succulents – only when its soil gets dry to the touch. Mammillaria Marksiana is drought-resistant and doesn’t need much water to thrive.

Do not overwater this cactus – in nature, its soil is fast-draining, meaning that Mammillaria Marksiana is not used to standing water in the soil. Overwatering is very likely to lead to waterlogging and root rot.

In winter, keep your Mammillaria Marksiana cactus dry or only lightly water it 1-2 times a month. Dormant in winter, Mammillaria Marksiana cacti require very little water, and it’s also much easier to trigger root rot in winter than summer.

Where to plant

To reduce the risk of waterlogging and root rot, plant Mammillaria Marksiana in porous, fast-draining soil. To increase drainage further, mix in coarse sand or perlite in a 1:1 ratio to the mix.

Unless winters are warm in your area, outdoor Mammillaria Marksiana should be potted. Potted plants are more mobile and easier to move inside to protect from cold in winter.

The Mammillaria Marksiana cactus prefers partial to full sunlight, so outdoors is where it will do best. Indoor growing is also possible, but be sure to place your cactus in a location that receives direct sunlight. If direct sunlight indoors is lacking, then you may use grow lights, but keep in mind that sunlight is preferable.

During extreme heat, temporarily move your Mammillaria Marksiana cactus to a shaded location to protect it from heat damage. Likewise, in winter, bring the cactus inside to protect it from cold.

General care information

A slow-growing cactus, Mammillaria Marksiana should be fertilized for consistent growth. Fertilization can be especially helpful if the soil of the cactus isn’t fresh.

Fertilize your Mammillaria Marksiana cactus with a cactus fertilizer mix diluted to half strength. Fertilization should be done throughout the growing season (spring and summer) once every month or two.

Aside from fertilization, repot the cactus as needed. Mammillaria Marksiana probably won’t be outgrowing its pot every year, so repotting every other year should be fine. But do keep in mind that yearly repotting allows you to have a look at the plant’s root health, as well as introduce it to some fresh, nutrient-filled soil.

Repot your Mammillaria Marksiana cactus in spring or summer. Before repotting, allow the soil to dry. Gently remove the pot, knock old soil off the roots, and remove any rotten or dead roots. Place the cactus into the new pot and keep it dry for about a week to allow it to recover.
