Parodia leninghausii

Parodia leninghausii, also known as the Parodia cactus or Notocactus leninghausii, is a small cactus native to South America. Here's how to care for it:

1. Light: Parodia leninghausii prefer direct sunlight. Place them near a sunny window where they can receive at least 6 hours of bright light per day. If growing them outdoors, ensure they get plenty of sun.

2. Temperature: They tolerate warm temperatures during the growing season but need a winter dormancy period with cooler temperatures (around 10-15°C).

3. Watering: Parodia leninghausii are cacti, meaning they prefer dry soil. Water them moderately during the growing season (spring and summer) when the soil is dry deep down. Reduce watering as autumn approaches and during winter. Ensure the pot has good drainage to prevent waterlogging.

Soil: Use a soil mix specifically designed for cacti, or add sand or perlite to regular potting soil to improve drainage.

4. Fertilization: Feed the cactus with a diluted balanced fertilizer during the growing season, approximately once a month. Avoid fertilizing in winter when the plant is dormant.

5. Pots: Use terracotta pots with drainage holes to allow for better soil drying.

6. Pruning: Parodia leninghausii generally do not require pruning. Simply remove damaged or dead parts as needed.

7. Common problems: Watch out for pests, such as mealybugs or aphids. If you find any, gently remove them with a cotton swab dipped in alcohol.

8. Winter dormancy: As mentioned earlier, Parodia leninghausii need a winter dormancy period with cooler temperatures and less watering. Reduce watering as autumn approaches to encourage this rest period.
