Everything it needs
9 essentials at a glance
Watering
Basella alba prefers consistently moist soil but should not be waterlogged.
Water the plant every 2-3 days during the growing season, adjusting to once a week in cooler months. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and leaf drop.
Light
This plant thrives in full sun to partial shade, ideally receiving 6-8 hours of direct sunlight daily.
It can tolerate some shade but may result in slower growth. Ideal placement includes a sunny garden bed or a trellis where it can climb and receive ample light.
Soil
Basella alba prefers well-draining, fertile soil with a pH range of 6.0 to 7.0.
A potting mix that includes compost, peat moss, and perlite is recommended to ensure good drainage and nutrient availability.
Humidity
The plant enjoys moderate to high humidity levels, ideally between 50-70%.
To increase humidity, mist the leaves regularly or place a humidifier nearby. Signs of low humidity stress include browning leaf edges and stunted growth.
Temperature
Basella alba thrives in warm temperatures, ideally between 70-90°F (21-32°C).
It is not frost-tolerant and prefers USDA hardiness zones 9-11. Protect the plant from extreme cold and heat by providing shade during the hottest part of the day.
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10 every 4-6 weeks during the growing season.
Reduce feeding in the fall and winter months. Signs of nutrient deficiency include yellowing leaves and poor growth.
Pruning
Prune Basella alba in late summer to encourage bushier growth and remove any dead or damaged leaves.
Use clean, sharp scissors or pruning shears. Deadheading is not necessary, but removing spent flowers can promote further blooming.
Repotting
Repot the plant every 1-2 years or when it becomes root-bound.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include roots growing out of the drainage holes and stunted growth. Follow these steps: gently remove the plant from its pot, loosen the roots, and place it in fresh potting mix.
Propagation
Propagation can be done through stem cuttings or seeds.
For stem cuttings, take a 4-6 inch cutting from a healthy plant, remove lower leaves, and place it in water or moist soil. For seeds, sow them directly in the soil after the last frost. The best time for propagation is in spring.
