Origin
Ambulia gratioloides (R.Br.) Baill. ex Wettst., commonly known as ambulia, is a plant species native to Southeast Asia. It can be found in countries such as India, Sri Lanka, and Thailand, and has also been introduced to other tropical regions around the world.
Common Names
Ambulia gratioloides is known by various other common names depending on the region. It is commonly called 'ambulia' or 'ambulia plant' in English-speaking countries, while in India it is known as 'ambutia'. In Southeast Asia, it may be referred to as 'dok mali' in Thai or 'chamestristu' in Sinhalese.
Uses
The ambulia plant is popularly used in the aquarium trade as an ornamental plant due to its attractive and delicate foliage. It is also known to be a fast-growing plant that can help purify the water in the aquarium. In traditional medicine, ambulia has been used as a treatment for various ailments, such as fever, cough, and rheumatism. Additionally, the plant is also used in Hindu religious rituals and is believed to have healing properties.
General Appearance
The ambulia plant typically grows to be between 10-40cm tall, with leaves that are narrow and elongated. The leaves are a light green color and are arranged in opposite pairs along the stem. The plant produces small white or light pink flowers that are densely clustered along the stem. Ambulia is a relatively easy plant to grow and is able to adapt to a variety of water parameters, making it a popular choice for beginner aquarists.
Light Requirements
Ambulia gratioloides requires moderate to high levels of light for optimal growth. In low light conditions, the plant may appear leggy and the color may fade.
Temperature Requirements
The plant fares best under a temperature range of 22-28°C (71-82°F). However, it can tolerate temperatures as low as 18°C (65°F) and as high as 30°C (86°F).
Soil Requirements
Ambulia gratioloides grows well in nutrient-rich substrates. A substrate high in organic content and rich in nutrients such as iron is preferred. The pH of the substrate should be between 6.0 and 7.5. A substrate that is coarse and well-drained is also recommended for optimal growth.
Cultivation Methods
Ambulia gratioloides, commonly known as lesser water plantain, is a popular aquatic plant with bright green leaves. Cultivating this plant is relatively easy, and it doesn't require any special skills. For the best results, plant it in a substrate with a nutrient-rich soil mixture and a bottom layer of coarse gravel or sand. Ambulia gratioloides is also compatible with other aquatic plants and can benefit from growing with them in the same aquatic environment.
Watering Needs
Ambulia gratioloides is an aquatic plant that grows in water, so it doesn't require watering in the traditional sense. However, this plant needs a well-regulated water supply to thrive. Regular water changes are essential for its growth, and it's also important to maintain a consistent water temperature and flow. Ambulia gratioloides prefers water that's slightly acidic to neutral (pH 6.0-7.5) and moderately hard (4-8 KH).
Fertilization
Ambulia gratioloides requires a steady supply of nutrients to grow strong and healthy. Fertilizers specifically designed for aquatic plants can provide the necessary nutrients. These fertilizers are usually high in nitrogen and contain trace elements like iron, manganese, and potassium that are vital for the plant's proper functioning. Use a liquid fertilizer once a week or add fertilizer tablets to the substrate as needed. It's important to follow the manufacturer's instructions and to avoid over-fertilization as this can lead to algae buildup and can endanger the plant's health.
Pruning
Regular pruning is essential for maintaining the shape and health of Ambulia gratioloides. This plant grows quickly and can easily overtake other plants in the same aquatic environment if left untrimmed. To prune it, use a clean pair of aquatic plant scissors and cut the stem just above the leaf. Be careful not to damage the healthy stem tissue while pruning. The trimmed parts can be used to propagate new plants. Prune regularly to encourage new growth and to keep the plant healthy and vibrant.
Propagation of Ambulia Gratioloides
Ambulia gratioloides is a popular aquatic plant among aquarists. Propagation of this plant can be achieved through different methods, including:
1. Stem cuttings:
Stem cuttings is one of the easiest methods of propagating Ambulia gratioloides. Cut a section of the stem and ensure it has a couple of leaves, and then plant it in a substrate. Within a few weeks, roots will grow from the cutting, and new shoots will appear.
2. Runner division:
ambulia gratioloides produces runners that branch out of the mother plant and form new plants. These runners can be separated from the mother plant and transplanted elsewhere in the aquarium. The separated runners will start developing new roots and shoots within days, resulting in new independent plants.
3. Seeds:
Ambulia gratioloides produces seeds that can also be used to propagate the plant. You can obtain new plants from the seeds by planting them in a substrate and ensuring they are well-aerated and moist. Although seeds take a longer time to germinate and grow than the other methods, it is still a viable option.
4. Tissue culture:
Tissue culture is another method of propagating Ambulia gratioloides. This method involves extracting a small section of the plant, such as the leaf, and placing it in a nutrient-rich media. The section will then begin to develop roots and shoot, which can be transplanted in the aquarium substrate.
Regardless of the method used, Ambulia gratioloides is an easy plant to propagate, and with proper care, it will thrive in the aquarium, creating a stunning water garden environment.
Disease and Pest Management for Ambulia Gratioloides
Ambulia gratioloides, also known as water nymph, is a fast-growing aquatic plant that is commonly used as an aquarium plant. Unfortunately, it is also prone to pests and diseases that can harm its growth and overall health. Here are some common diseases and pests that might affect the plant and ways to manage them.
Diseases
Bacterial infections: Bacterial infections can cause yellowing or browning of the leaves of Ambulia gratioloides. To prevent bacterial infections, make sure to maintain clean and healthy conditions in the aquarium, including good water circulation and frequent water changes. If you notice any signs of bacterial infection, remove the infected plant from the tank and dispose of it properly.
Fungal infections: Fungal infections can cause brown spots or lesions on the leaves of Ambulia gratioloides. To prevent fungal infections, make sure to keep the water in the aquarium clean and avoid overcrowding the tank. If you notice any signs of fungal infection, remove the infected plant from the tank and dispose of it properly.
Pests
Snails: Snails can be a serious problem for Ambulia gratioloides, as they can eat the leaves of the plant and cause significant damage. To manage snails, you can manually remove them from the tank or use snail traps. You can also consider introducing snail-eating fish, such as loaches or pufferfish.
Aphids: Aphids are small, sap-sucking insects that can cause stunted growth and yellowing of the leaves in Ambulia gratioloides. To manage aphids, you can introduce predatory insects, such as ladybugs or lacewings, or you can spray the plants with a solution of soap and water.
Algae: Algae can grow on the leaves of Ambulia gratioloides and prevent the plant from receiving enough sunlight and nutrients. To manage algae, you can reduce the amount of light in the aquarium, increase the number of water changes, and consider using an algae-eating fish, such as a Siamese algae eater.
By following these guidelines, you can help protect your Ambulia gratioloides from pests and diseases and ensure its healthy growth in the aquarium.
