Ammania Sp Bonsai AQUARIUM Plant Care

The plant is quite whimsical, therefore it requires attention and responsibility from the owner.

Beginners may encounter some difficulties, but as they gain experience, caring for Ammania will become easier.


The herbaceous plant reacts negatively to changes in water temperature. Its excessive decrease or increase can be a disastrous factor. The lower temperature limit is + 22 ° С, the maximum is up to + 28 ° С. The optimal indicator is + 25 ° C.

The situation with water hardness is not so critical. In order for Ammania bonsai to grow and develop normally, a degree of hardness of 5-14 ° dH is suitable for it.

It is also necessary to control the acidity level in the range from 6.5 to 7.5 pH. The aquarium should be equipped with filters around the clock to ensure the right amount of water.


Ammania needs light 12 hours a day. The lighting should be moderate, but the plant feels comfortable in low shade conditions.

Excessive lighting can lead to the formation of filamentous algae, and lack of light can lead to pallor and stretching of the plant.

To organize a suitable lighting brightness, it is necessary to monitor the state of the rotala.

If it looks healthy, new leaves with red tops appear on it, then everything is fine with the light.

When changing the color towards lightening or darkening, the light level should be corrected.

Ammania Bonsai planting medium

The soil is an additional source of nutrients for rotala, the main part comes from the water. The soil should be light and fine, contain iron and other trace elements.

The bottom of the aquarium can be covered with fine gravel or river sand, the optimal layer height is 1.5 cm. Stones and driftwood are placed on the ground.

Fertilizer for Ammania Bonsai

Ammania needs additional fertilizing to enhance growth and color saturation of the stem and leaves. Mineral complexes in liquid form are introduced during water replacement. For feeding, micro and macro fertilizers are needed, which include nitrates, iron, phosphates and trace elements.

Ammania Bonsai PRUNING

Pruning is rarely done because the grass grows slowly.

Pruning rules:

  1. You need to cut off the top, removing 2/3 of the stem.
  2. It can be used for reproduction by planting it in a new place.

Ammania should not form large thickets, since under such conditions its growth stops, the processes fall off and rot.

Ammania Sp Bonsai propagation methods and planting

The plant is propagated by cuttings – the top is cut off, which is planted at some distance from the main bush. This will provide the cutting with enough light and nourishment.

The acclimatization of the cuttings can take a long time, depending on the care of it. When planting in the ground, you should adhere to the “ladder” scheme. After about 1-2 months, the cuttings will grow 1-2 cm.

It is possible to breed a plant with cuttings according to the same principle in a separate container with soil and water. After strong shoots with round leaves are formed above the water, they are planted in a permanent place.

Ammania Bonsai growing conditions

If the growing conditions in a new place are organized correctly, then the plant quickly takes root in the aquarium and begins to participate in metabolic processes.

When planting rotals in a small container, choose the back or middle line.

In large aquariums, foreground and middle ground. Plants are best placed in groups; alone, they look ineffective.

The fragility of the stem requires careful handling, so Ammania should not be placed near the filter and aerator. Under a stream of oxygenated water, the plant can break.

In order for the grass to remain beautiful and healthy, it should not be placed in the same aquarium with large and too nimble fish.

Diseases that can affect Ammania bonsai are associated with:

  • poor conditions of detention – lack of light and inappropriate temperature conditions;
  • deficiency of vitamins and microelements (iron, potassium, phosphorus, nitrogen, sulfur, carbon dioxide).
