Pelargonium tetragonum, commonly known as the Square-Stalked or Four-Angled Pelargonium, is a fascinating and unique member of the Pelargonium genus. This succulent perennial plant is native to South Africa and is prized for its distinct square-shaped stems, which give it a striking appearance. The Square-Stalked Pelargonium is a favorite among succulent enthusiasts and gardeners alike due to its charming appearance and relatively low maintenance requirements.

Cultivation:

1. Sunlight: Provide your Pelargonium tetragonum with plenty of bright sunlight. Place it in a location where it can receive at least 6-8 hours of direct sunlight per day. A south or west-facing windowsill is ideal, or you can grow it outdoors in a sunny spot.

2. Soil: Use a well-draining potting mix that is specifically designed for succulents and cacti. A mix that contains perlite or sand will help ensure good drainage.

3. Container: If growing in a container, make sure it has drainage holes to prevent waterlogged soil, which can lead to root rot.

4. Watering: Pelargonium tetragonum is a succulent, and like most succulents, it prefers to dry out between waterings. Water sparingly, allowing the soil to become almost dry before watering again. During the growing season (spring and summer), water more frequently, but still be cautious not to overwater.

5. Temperature: These plants prefer warm temperatures. Keep them in an environment with temperatures between 65°F to 80°F (18°C to 27°C). Protect them from frost and cold drafts, especially during the winter months.

6. Fertilization: Fertilize your Pelargonium tetragonum sparingly during the growing season, typically from spring to early fall. Use a diluted, balanced liquid fertilizer for succulents every 4-6 weeks. Avoid fertilizing during the dormant winter months.

7. Pruning: Prune your Square-Stalked Pelargonium as needed to maintain its shape and remove any dead or leggy growth. This can be done throughout the year.

8. Propagation: Propagate Pelargonium tetragonum through stem cuttings. Allow the cuttings to callus for a few days before planting them in a well-draining succulent mix. They should root within a few weeks.

9. Pests and Diseases: Keep an eye out for common succulent pests like mealybugs and aphids. Treat infestations promptly with insecticidal soap or neem oil. Ensure good air circulation to prevent fungal diseases.

10. Repotting: Repot your Square-Stalked Pelargonium every 2-3 years or when it outgrows its container. Choose a slightly larger pot and refresh the soil during repotting.

By following these cultivation tips, you can enjoy the unique beauty of Pelargonium tetragonum and keep it thriving as a charming addition to your succulent collection or garden.
