Hydrocotyle vulgaris (5cm Pot) Care Guide

Hydrocotyle vulgaris, commonly known as Pennywort or Marsh Pennywort, is a fast-growing aquatic plant with round, vibrant green leaves. It is a great addition to aquariums for creating a lush, natural look. This plant can be used in both foreground and midground aquascaping and is adaptable to a variety of conditions. Below is a concise care guide:

Care Requirements

• Tank Size: Suitable for tanks of 10 gallons or larger.
• Lighting: Moderate to high; bright lighting helps the plant grow faster and maintain vibrant foliage.
• Temperature: 20–28°C (68–82°F); ideal for tropical aquariums.
• pH Range: 6.0–7.5; slightly acidic to neutral water is ideal.
• Water Hardness: Soft to moderate (2–12 dGH).
• Substrate: Grows well in nutrient-rich substrate but can also be left floating.
• Growth Rate: Fast; will spread quickly if not trimmed regularly.
• CO2 Requirement: Optional; CO2 supplementation will promote faster growth and more vibrant foliage but is not necessary for this hardy plant.

Key Tips

• Pruning: Trim regularly to keep the plant compact and prevent it from overtaking other plants.
• Propagation: Easily propagated by cutting the stem and replanting the cuttings.
• Fertilization: Dose liquid fertilizers, particularly those rich in iron and micronutrients, to enhance growth and leaf health.
• Water Flow: Prefers moderate water flow; too strong a current may dislodge the plant.
• Placement: Ideal for midground or foreground placement in aquascapes, creating a carpeting or bushy effect.
• Support: Can be attached to rocks or driftwood or left floating for a more natural look.

Hydrocotyle vulgaris is a versatile and easy-to-care-for plant that adds a lush, green appearance to any aquarium. With regular trimming and basic care, it will thrive and create a beautiful, vibrant aquascape.
