While fertilizers are not usually necessary for this plant, adding a slow-release fertilizer to the substrate can help support growth.
Cultivation methods
Hydrosme zenkeri Engl. is an aquatic plant that is ideal for cultivation in an aquarium. It is relatively easy to cultivate and can thrive in low-light conditions. The plant can be grown alone or in groups, depending on the available space in the aquarium.
Since Hydrosme zenkeri Engl. is a submerged plant, it is essential to ensure that it is fully submerged in water. The plant can grow up to a foot tall, so the aquarium should be deep enough to accommodate its growth. The pH range should be between 6.5 and 7.5. The water hardness should be neutral to slightly acidic, ranging from 4 to 8 dKH.
Watering needs
Hydrosme zenkeri Engl. thrives in aquatic environments and requires constant water to grow. The water in the aquarium should be changed frequently, ideally on a weekly basis. It is recommended to substitute at least 30% of the water in the aquarium weekly. This helps to reduce the buildup of harmful chemicals in the water.
The aquarium water's temperature should be between 20°C and 28°C, and the water should be well-aerated and circulated.
Fertilization
Hydrosme zenkeri Engl. benefits greatly from regular fertilization. The plants' growth and coloration are significantly impacted by fertilizers. Liquid fertilizers or fertilizers in tablet form should be used for optimal results. Potassium and nitrogen are the critical components of a good fertilizer.
It is essential to note that fertilization requires balance, as over-fertilizing can lead to algae growth, which is harmful to the plant. Fertilizers should be added to the water or substrate at least once a week.
Pruning
Pruning is a necessary part of cultivating an aquarium that includes Hydrosme zenkeri Engl. Regular pruning helps to manage the plant's size and encourage healthy growth and branching. Diseased or damaged parts of the plant should be removed promptly to avoid spreading the disease.
Aquarists should be careful not to damage the plant when pruning. Careful use of scissors or pruners is necessary to avoid causing damage to the surrounding leaves or stem. Regular pruning should be done, preferably every two to three weeks, to encourage healthy growth habits.
Propagation of Hydrosme Zenkeri Engl.
Hydrosme Zenkeri Engl. is commonly known as the water yam. It is a highly nutritious edible root tuber crop indigenous to West Africa and can be propagated by various methods such as:
1. Stem Cutting Method
The stem cutting method is the most common method of propagating Hydrosme Zenkeri Engl. Cuttings are taken from the stems of the mature plant and planted in soil. It is important to ensure that the cuttings are taken from a healthy plant with enough foliage and roots. Cuttings should be planted in nutrient-rich soil mixed with organic manure and kept moist throughout the rooting and growth process. The new plantlets will grow in a few weeks and will be ready for transplanting to a permanent location.
2. Sucker Division Method
The sucker division method involves separating a healthy suckers from the parent plant and planting separately in soil. A sucker is a small plant that has grown from the parent plant's roots. To propagate using this method, healthy suckers are dug up and separated from the parent plant. Ensuring that the suckers have enough roots and foliage is important. The suckers can be planted immediately in nutrient-rich soil mixed with organic manure and watered frequently until the new plants become established. The new plants can then be transplanted to a permanent location.
3. Tissue Culture Method
The tissue culture method involves propagating Hydrosme Zenkeri Engl. in a laboratory. This method is commonly used to produce disease-free and genetically identical plants. Tissue samples are taken from the parent plant and are grown in a nutrient-rich medium under sterile conditions. Auxins and cytokinins are added to the medium to encourage growth and development. In a few weeks, new plantlets are produced, and the new plants can then be transferred to soil and grown to maturity.
Overall, Hydrosme Zenkeri Engl. can be propagated using various methods, but it is essential to ensure that the method selected yields healthy and vigorous new plants.
