Cardamine lyrata Care Guide (5cm Pot)

Cardamine lyrata, also known as “Japanese Cress” or “Water Cress,” is a lovely aquatic plant that can enhance the beauty of your aquarium with its delicate, fern-like leaves. It is an easy-to-care-for plant that adds vibrant green color and texture to your tank.

Care Requirements:

• Light: Prefers moderate to high light levels for optimal growth. Under low light conditions, it may become leggy and sparse. For best results, provide bright, indirect light or aquarium lighting with a good spectrum for plant growth.
• Temperature: Thrives in temperatures between 18°C to 28°C (64°F to 82°F). It can tolerate slightly cooler or warmer water but performs best within this range.
• pH Range: Tolerates a wide pH range, from 6.0 to 8.0, with a preference for neutral to slightly acidic conditions.
• Water Hardness: Can adapt to a range of water hardness but performs best in soft to moderately hard water.
• Water Flow: Prefers moderate water flow. Strong water currents can damage its delicate leaves, while stagnant water can promote algae growth.
• Substrate: Can be planted in a nutrient-rich substrate or left floating. It roots well in the substrate but can also grow as a floating plant.
• Fertilization: Regular dosing of liquid fertilizers or substrate fertilization will support its growth. A fertilizer rich in iron and micronutrients is beneficial for healthy foliage.

Care Tips:

• Propagation: Propagates easily through stem cuttings. Simply cut off healthy stems and replant them into the substrate, or let them float and establish roots. It will quickly grow new shoots from the cut ends.
• Pruning: Regular trimming will help maintain a neat appearance and prevent the plant from overgrowing. Cut back any old or dying leaves to encourage fresh growth.
• Floating or Anchored: Cardamine lyrata can be kept floating or planted in the substrate. If growing submerged, make sure the plant’s roots are properly anchored.
• Growth Rate: It is a relatively fast-growing plant. Be prepared to trim back new shoots to prevent it from overtaking the aquarium.
• Water Quality: Keep the water clean and well-filtered. Regular water changes are essential to maintain the plant’s health, especially in aquariums with high fish populations.

Additional Notes:

• Aquarium Placement: Suitable for the midground or background in aquariums. It can also be used as a floating plant for a more natural look. It pairs well with other aquatic plants, such as ferns and mosses.
• Compatibility: Safe for all aquatic animals, including fish, shrimp, and snails. It will not harm other species and provides a nice hiding place for small creatures.
• Pests: Generally resistant to pests but can occasionally attract algae or small snails. Cleaning the leaves regularly helps prevent algae buildup.
• Maintenance: Cardamine lyrata is low-maintenance but does need occasional pruning to keep it from overtaking other plants in the tank. Ensuring proper water parameters will keep it growing healthily.

General Advice: Cardamine lyrata is a hardy and attractive plant that works well in a variety of aquariums. It adapts easily to different water conditions and grows quickly, making it a great choice for both beginners and experienced hobbyists. With regular care and attention, it will thrive in your aquarium and add a lush, green element to your aquascape.
