Care Guide
Lemon Bacopa thrives in a range of conditions, making it suitable for both novice and experienced aquascapers.
- Lighting: It prefers moderate to bright light, ideally ranging from 2 to 4 watts per gallon. While it can tolerate lower light conditions, optimal growth and coloration are achieved with sufficient illumination.
- Water Parameters: This plant thrives in a pH range of 6.0 to 7.5, with a temperature range between 22°C to 28°C (72°F to 82°F). Good water circulation and consistent temperature are essential for optimal health.
- Pruning: Regular pruning is beneficial to encourage bushier growth and prevent the plant from becoming leggy. Trim back any overgrown stems to promote lateral branching and maintain a compact shape.
- Substrate: A nutrient-rich substrate will enhance growth, although Lemon Bacopa can adapt to various substrate types.
