My Limnophila Sessiliflora Is Turning Brown

Cultural Requirements

• Limnophila sessiliflora is a herbaceous perennial. This means that, given warm winter climates, the plant will persist year after year. When winter conditions are harsh, the plant dies back in the winter. Temperatures below 59 degrees Fahrenheit are not capable of sustaining healthy Limnophila sessiliflora. Temperatures within the 68 to 79 degree range are optimum. Temperatures exceeding 83 degrees can cause plant damage. Healthy, green Limnophila sessiliflora grow in aquariums where the majority of their growth is underwater. Like all plants, the aquatic Limnophila sessiliflora requires carbon dioxide and adequate gas exchange. Emergent leaves help provide the rest of the plant with gas exchange. Plant leaves become lackluster and may appear brown when aquarium water is stagnant.

Life Cycle

• Limnophila sessiliflora propagate via plant remnants. Under optimum temperature and moisture conditions, plant portions form new growth and eventually produce a mature plant. Mature plants produce leaves and flowers. In warm climates, such as those found in Texas and Florida, flowers bloom from July to November. Brown seed heads emerge after flowers fade. This kind of earth-toned seed head is normal during the winter months. The rest of the plant, however, should remain green.

Invasive Behavior

• Limnophila sessiliflora are highly adaptable plants with an effective method of propagation. When the plant escapes cultivation, it grows and reproduces rapidly. New plant growth chokes waterways. In cool climates the plants die back in winter but warm climate waterways do not receive seasonal relief. Whether outdoors or in a controlled aquarium environment, the plant requires a growing medium for its root system. Without a nutrient-rich growing medium, the plant will not survive. Leaves, lacking nourishment, will turn brown and the plant will fail to thrive.

Considerations

• Limnophila sessiliflora is found in beginner aquarium kits because the plant is hardy and easy to grow. Should your Limnophila sessiliflora's leaves turn brown, check your aquarium's temperature, provide a nutrient-rich growing medium and a well aerated tank. If growing conditions are adequate, then consider purchasing new plants from a reputable nursery. Some kit plants lack vigor.
