**1. Lighting:**
- Provide moderate to high-intensity lighting. Corkscrew Vallisneria can adapt to various light conditions, but higher light levels often promote more vigorous growth and the expression of its characteristic corkscrew shape.

**2. Substrate:**
- Plant Corkscrew Vallisneria in a nutrient-rich substrate. While it can tolerate various substrates, a nutrient-rich substrate or the use of root tabs can support its growth and health.

**3. Fertilization:**
- Regularly dose a comprehensive liquid fertilizer to supply essential nutrients. Corkscrew Vallisneria, like other Vallisneria species, benefits from additional nutrients to support its growth.

**4. CO2 Injection:**
- While not strictly necessary, providing a source of CO2 can enhance growth and overall health. Corkscrew Vallisneria can thrive in both low-tech and high-tech setups.
