Albuca polyphyllum, commonly known as the pregnant onion plant, is a fascinating and relatively easy-to-care-for succulent. Here’s a care sheet to help you keep your Albuca polyphyllum thriving:
 
Light:
Light Requirements: Place your Albuca polyphyllum where it can receive bright, indirect light. It thrives in bright light conditions but should be protected from direct sunlight, especially during the hottest parts of the day.
 
Temperature and Humidity:
Temperature: Keep the plant in a warm environment, ideally between 65°F to 75°F (18°C to 24°C) during the growing season. It can tolerate higher temperatures if there is good airflow.
Humidity: This plant prefers average indoor humidity levels. It can tolerate slightly drier conditions, typical of most succulents.
 
Watering:
Watering Schedule: Water thoroughly but allow the top inch (2.5 cm) of soil to dry out between waterings. During the active growing season (spring and summer), water more frequently, but reduce watering in the winter when growth slows down.
Watering Method: Water at the base of the plant, avoiding getting water on the bulb or leaves to prevent rotting.
 
Soil:
Potting Mix: Use a well-draining cactus or succulent potting mix. You can also mix regular potting soil with perlite or coarse sand to improve drainage.
 
Fertilization:
Fertilizer: Feed with a balanced liquid fertilizer diluted to half-strength during the growing season (spring and summer) about once a month. Avoid fertilizing during the dormant season (fall and winter).
 
Repotting:
Repotting: Repot Albuca polyphyllum every 2-3 years or when it outgrows its pot. Spring is the best time for repotting. Use a slightly larger pot with fresh potting mix.
 
Dormancy:
Dormancy Period: Albuca polyphyllum typically goes dormant in the fall and winter. During this time, reduce watering and withhold fertilizer to mimic its natural growth cycle.
 
Pest Control:
Pests: Keep an eye out for common houseplant pests like aphids, spider mites, and mealybugs. Treat any infestations promptly with insecticidal soap or neem oil.
 
Special Care Tips:
Bulb Care: The swollen bulb of Albuca polyphyllum stores water, so it's crucial not to overwater. Allow the bulb to dry out slightly between waterings to prevent rot.
Leaf Shedding: It’s normal for Albuca polyphyllum to shed its older leaves periodically. Trim off any yellow or dry leaves at the base to maintain plant health.
 
Propagation:
Propagation: Propagate Albuca polyphyllum from offsets that develop around the base of the bulb. Carefully separate these offsets and plant them in a separate pot with well-draining soil.
 
By following these care guidelines, you can enjoy a healthy and thriving Albuca polyphyllum in your home or garden.
