Classic Mid-Ground Lobelia Cardinalis
As a mid-ground plant, Lobelia cardinalis offers a unique set of features that make it a standout choice in aquascaping:

It requires little height to cover other plants and hence doesn’t compete for space with other plants, something that in addition to its bright color makes it popular for the mid-section of the tank. Also, its flexibility in the choice of light and water CO2 content makes it simple to use for new aquarium owners.
Aquarium Planting of Lobelia Cardinalis
Growing Lobelia cardinalis in an aquarium is very easy, but it’s important that a few points are observed. Here are some key considerations:
Planting Lobelia Cardinalis
- Substrate Preparation: Organic substances should be used to improve root growth as well as seedbed nutrients. These are nutrients that can be supplemented if the substrate is soil-less or if it is depleted of nutrients such as root tab
- Placement: Lobelia cardinalis should be developed on the mid-ground of the tank. Make sure it has adequate room to grow and do not over-populate this plant with other plants.
- Planting Technique: You should also cut the roots with a pair of scissors to some extent before planting so that they can grow again. Place its base into the substrate and then put the roots under it and cover them very softly.
Lobelia Cardinalis-Only Planted Tank
It will create a tank only with Lobelia cardinalis, which will focus on the virtues of the plant. To achieve this:
- Organize it in a manner so that the coloration and structure of the plant can be seen to contrast.
- Achieve overgrowth through the use of different planting heights, adjusted by pruning and repositioning stems.
Mixed Planting with Other Aquatic Plants
When planting Lobelia cardinalis with other plants, consider the following:
- Grow it alongside plants with different leaf structures and or colors, like the Anubias or Rotala species.
- Make sure that all the plants receive similar parameters regarding water, such as temperature and light.
Lighting, Temperature, and Other Requirements
- Lighting: The best temperature range is moderate to highlight intensity, which is between 2 and 3 watts per gallon. Bright lighting gives the leaves a reddish tinge Illustration: The leaf picture at the bottom is at the same angle as the light source but at a higher intensity.
- Temperature: Lobelia cardinalis enjoys a warm climate and specific temperature should be maintained at 68-78 F / 20-25 C. In low-temperature environments, though, try to use the lower part of this range.
- CO2 and Fertilization: While not mandatory, CO2 supplementation and liquid fertilizers enhance growth and coloration.
- Water Parameters: Maintain a pH of 6.0-7.5 and soft to moderately hard water(2-12 dGH).
