How to care for a Mammillaria Spinosissima
Watering Mammillaria Spinosissima
Water your Mammillaria Spinosissima every 2 to 3 weeks during the growing season (spring and summer). Use lukewarm water and pour it next to the pot, not directly on the plant, so the soil absorbs it easily. Allow the potting soil to dry completely between waterings to prevent root rot. Watering once a month during the winter is sufficient, as the cactus is dormant.
Light for Mammillaria Spinosissima
Mammillaria Spinosissima loves plenty of light, preferably direct sunlight. Place it on a bright windowsill or balcony, for example, next to your pancake plant for a playful mix. Direct sunlight promotes flowering and keeps the plant compact and healthy. Be careful with bright afternoon light behind glass; an hour or two of slanting sunlight is ideal to prevent sunburn.
Common problems
Yellow leaves
Although cacti don't have leaves in the traditional sense, their shoots and shoots can still turn yellow. This is usually a sign of overwatering or insufficient light. Check that the potting soil is well-draining and adjust the location to a brighter spot. Read more tips in the blog post " Help, I can even kill my cactus ."
Plant dripping
A leaking cactus almost always indicates overwatering or damage to the epidermis. Remove the plant from its pot to rule out root rot and replace the wet soil with fresh, dry substrate and a scoop of pumice . Let the plant dry for a week without watering before resuming normal care.
Plagues
Mammillaria Spinosissima can be affected by mealybugs or spider mites, especially in dry conditions. Inspect the plant regularly and treat emerging pest infestations with our sticky traps for fungus gnats and, if necessary, a herbal pesticide. For tips on controlling mealybugs, please visit the " Pests and problems with cacti " page (general approach).
Carrots emerge from the bottom of the pot
When roots appear at the bottom of the pot, it means the plant is ready for a larger pot. Repot your cactus one size larger in spring and use cactus potting soil or mix your own potting soil with extra perlite. After potting, make sure to keep the soil dry for a few weeks to prevent root damage.
Brown edges on the 'leaves'
With Mammillaria, the edges of the bulbs can turn brown. This is often caused by too much direct sunlight during heat waves or insufficient water during the growth phase. Provide some shade during bright midday light and occasionally give a little more water in the summer. This will prevent permanent discoloration of the shoots.
