Mammillaria parkinsonii, also known as owl-eye pincushion or owl-eye cactus, is a species of flowering plant in the family Cactaceae. It is endemic to Queretaro, Mexico. Mammillaria parkinsonii is listed as Endangered due to a limited distribution (extent of occurrence ca 2,500 km2), severe fragmentation, a continuing decline due to illegal collection, and degradation of its habitat across its range. Clarification of the taxonomic status of this species is a research priority. It was first described by Ehrenberg in 1840 in Linnaea 14: 375.
Owl eye pincushion has strong resistance to disease and tolerates normal care without becoming ill easily. However, it can be vulnerable to mealybugs, which may cause some damage but are typically not a serious problem. In terms of care, Owl eye pincushion is drought-tolerant and does not need frequent watering. It can withstand long gaps between waterings and requires little fertilizer. That said, it is very prone to root rot if lighting is poor and it is overwatered. Overall, Owl eye pincushion is suitable for people who prefer to spend less time caring for their plants, but it remains important to understand and meet its basic needs. It is especially well-suited for people who are often away for long periods and might forget to water regularly.
How to keep Mammillaria Parkinsonii.
Light
Owl eye pincushion comes from habitats with dappled light, like the understory of forests or rocky sites that offer natural shade. It prefers partial sun but is also able to tolerate full sun.
Water
The Owl Eye Pincushion is a drought-tolerant plant that only needs thorough watering when the soil is dry. During the growing season, from spring to fall, water the plant once or twice a week. In winter, reduce watering to just once a week. To prevent soil compaction, use rainwater or distilled water instead of tap water.
Humidity
This plant prefers dry conditions, so don't mist it. However, watering it less often can also thrive in higher humidity.
Temperature
Although Owl eye pincushion can tolerate some heat, it mostly thrives and grows in cooler seasons and becomes dormant in summer. In hot summer conditions, provide shade to avoid scorching from intense sunlight. Watering should be reduced or paused during the hottest period to prevent root rot. The plant grows vigorously in winter and spring. Provided the temperature does not drop too low, it will keep growing steadily.
Fertilizer
For Owl eye pincushion, light applications of fertilizer 1-2 times a year during the growing season are sufficient. Do not fertilize in winter or summer, when it is dormant. Reduce fertilizer for plants that have been repotted and wait a couple of months after repotting before applying feed. Fertilizing promotes healthy growth and encourages blooms.
Pruning
The Owl Eye Pincushion plant has a compact shape and is known for its distinctive white spines. To keep it healthy and looking its best, prune it in early spring. Use clean tools to remove any dead segments, which will help encourage new growth. Pruning also improves airflow around the plant, reduces the risk of fungal infections, and maintains its appealing shape. Be sure to handle the plant carefully to avoid injury from its spines.
Pot & Repot
Repot the Owl eye pincushion in spring or summer, selecting a pot slightly larger than the current one that has good drainage. Use a well-draining, sandy or gritty cactus mix. Handle it carefully to avoid the spikes. Allow the cactus to dry out before repotting to prevent root rot. After repotting, wait for a week before watering so the roots can heal.
