Cardinal Flower

The Cardinal Flower (Lobelia cardinalis) is a striking and vibrant aquatic plant known for its bright red flowers and lush green foliage. The Cardinal Flower is suitable for both beginners and experienced hobbyists, thanks to its moderate care requirements and adaptability.

Planting and Placement

Substrate: Cardinal Flowers thrive in a nutrient-rich substrate. Use pond soil and supplement with root tabs to provide essential nutrients. Plant the Cardinal Flower by burying its roots in the substrate, ensuring the crown (where the roots meet the leaves) is above the substrate to prevent rot.

Light Requirements: Cardinal Flowers require moderate to high lighting to thrive. Proper lighting promotes healthy growth and vibrant coloration of the leaves and flowers.

Water Conditions:

• Temperature: The ideal temperature range for Cardinal Flowers is between 68°F and 82°F.
• pH: They prefer slightly acidic to neutral water, with a pH range of 6.0 to 7.5.
• Hardness: Soft to moderately hard water (3 to 15 dGH) is suitable for Cardinal Flowers.

Maintenance

Pruning: Regular pruning is necessary to maintain the health and appearance of Cardinal Flowers. Remove any dead or yellowing leaves to promote new growth. Pruning also helps manage the plant’s size and prevents it from overshadowing other plants.

Fertilization: Cardinal Flowers benefit from regular fertilization. Use root tabs to deliver nutrients directly to the roots. Liquid fertilizers can also be used to supplement water column nutrients, particularly in tanks with other plants.

Propagation

Cardinal Flowers propagate through runners and side shoots. To propagate, carefully separate the new plantlets from the main plant once they have developed several leaves and a sufficient root system. Plant these new shoots in the substrate, ensuring they have adequate space to grow.
