Cultivation of Isotoma fluviatilis ‘Alba’:
Sunlight

Watering
Regular watering is essential for the health and vitality of White Star Creeper, especially during the summer months. The soil should be kept consistently moist but not waterlogged.

Soil
Isotoma fluviatilis ‘Alba’ prefers moist, well-drained soil. It thrives in soil that retains moisture without becoming overly saturated.

Propagation
White Star Creeper can be propagated through division or seed.
Division: In early spring, carefully dig up the plant and gently separate it into smaller clumps. Ensure each division has an adequate root system. Replant the divisions in well-drained soil, maintaining the same depth as the original plant. Water the newly divided clumps regularly to promote establishment.
Seed: White Star Creeper can also be propagated from seeds. Sow the seeds in well-drained soil in the spring. Cover them lightly with soil and keep the soil consistently moist. Germination typically occurs within 2-4 weeks. Once the seedlings have developed a few sets of true leaves, they can be transplanted into their permanent location.
Additional Care Tips:
- Fertilize White Star Creeper once a month during the growing season using a balanced fertilizer to promote healthy growth and abundant blooms.
- Regularly deadhead the spent flowers by pinching them off with your fingers. This encourages the plant to produce more blooms and maintains a tidy appearance.
- Prune White Star Creeper in late winter or early spring to remove any dead or damaged branches. Thinning out the plant during this time also improves air circulation and allows more light to reach the interior, promoting overall plant health.
