Description

Pogostemon helferi, also known as Downoi, is an aquatic plant that originates in Thailand. Due to its unique wavy leaves and ease of care, they’ve become a popular aquarium plant. They are often used as a foreground plant in various aquascapes.

Pogostemon helferi has been known in the scientific community for over 120 years. When it was first discovered in Burma and Thailand, scientists found it around the edge of streams. This explains why it grows so well when attached to limestones. However, the plant was introduced to the aquarium hobby in 1996 by Nonn Panitvong and Arthit Prasartkul. Since then, the plant has been used in various aquascapes.

One of the reasons why this plant is so appealing to aquascapers is because of its adaptability. In their native habitat in Thailand, Pogostemon helferi live in various environments. Throughout the seasons, and depending on the amount of rainfall, the plant may grow as a emersed plant or a submersed plant.

Even though Pogostemon helferi hasn’t been in the aquarium hobby for very long, it has quickly become a favorite among many aquascapers. Considering its unique appearance, versatility, and the ease of care, it’s understandable why so many hobbyists want to incorporate the plant into their aquascapes.

Pogostemon Helferi Care

Pogostemon helferi can be planted in the substrate of an aquarium and will produce a beautiful low star-shaped growth pattern if given lots of light. Even though it will still grow in low light environments, the growth will not be as robust. The optimum parameters for Pogostemon helferi consists of a pH of 6-7.5, temperatures of 68-86°F (20-30°C), and high levels of nutrients. Nutrients can be provided in the form of root tabs or liquid fertilizers. For best results, root tabs should be inserted into the substrate regularly. Adding CO2 injection will help it grow more quickly and more robust as well. Dead leaves should be clipped off, rather then letting it rot on the plant. If the old leaves are allowed to stay on the plant, it could stunt new growth.

Water changes will benefit the plant, so it should be done regularly. Replacing a lot of water in the tank can cause drastic changes in the water parameters, so this should be avoided. If there are fish in the same tank, high volume water changes can be unsafe for them as well. Instead, small water changes that are done frequently are better. For example, 10% water changes on a weekly basis or 20% water changes every other week can be beneficial. When adding new water into the aquarium, make sure that the water parameters are similar to the existing water in the tank. This includes the water pH and temperature. If the parameters are drastically different, even small water changes can become dangerous.

Regarding the lighting requirements for Pogostemon helferi, they need a lot of light. The aquarium light should be kept on for 8-10 hours a day to ensure proper growth. They should be planted in an area within the aquarium that would allow them to absorb the light as well. Tall plants that have overhanging growth may block the light, and this should be avoided.

Pogostemon helferi is very easy to grow, and exceptionally hardy once it is established. Therefore, this plant is great for both beginners and advanced hobbyists.

Planting Pogostemon Helferi

In order to prepare Pogostemon helferi for planting, it should be acclimated to the new environment. The plant is usually sold in pots. This pot can be planted directly into the aquarium substrate. This will allow the plant to get used to the new water parameters with minimal disturbance, especially to the root system. Once the plant is well-acclimated to the new environment, it can be taken out of the pot. Gently separate the plant into individual stems. Be careful not to damage the leaves and roots.
