Light
Hydrocotyle verticillata Thunb. var. triradiata (A. Rich.) Fern requires moderate to high light conditions for healthy growth. Too much light can lead to excess algae growth, which can affect the plant's health.
Temperature
The ideal water temperature range for Hydrocotyle verticillata Thunb. var. triradiata (A. Rich.) Fern is between 18°C to 27°C. Extreme temperatures can lead to a sluggish growth rate or even death of the plant.
Water Quality
Hydrocotyle verticillata Thunb. var. triradiata (A. Rich.) Fern prefers slightly acidic to neutral water conditions with pH levels ranging between 6.5 and 7.5. The plant also requires good water circulation and high dissolved oxygen levels to facilitate healthy growth.
Substrate
The plant thrives well in nutrient-rich substrates such as sand and clay soils. Soils rich in organic matter can inhibit Hydrocotyle verticillata Thunb. var. triradiata (A. Rich.) Fern's growth as the conditions favor the growth of other plant species over the Hydrocotyle verticillata Thunb. var. triradiata (A. Rich.) Fern.
Fertilizers
Hydrocotyle verticillata Thunb. var. triradiata (A. Rich.) Fern is a heavy feeder and requires frequent fertilization to thrive. The plant requires potassium-rich fertilizers alongside other essential micronutrients such as iron and sulfur.
Cultivation methods
Hydrocotyle verticillata Thunb. var. triradiata (A. Rich.) Fern. is a versatile plant that can be propagated both in-water and in substrate. The plant can be grown in aquariums and outdoor ponds with ease. The ideal temperature range for its growth is between 72°F-82°F (22°C-28°C).
The plant prefers soft, slightly acidic water with a pH range of 6-7. It requires moderate to high lighting, and its growth rate is faster in nutrient-rich substrates.
Watering needs
Hydrocotyle verticillata Thunb. var. triradiata (A. Rich.) Fern. prefers to have its roots continuously wet. The plant should be watered frequently, and the soil should never be allowed to dry out completely.
The plant is very sensitive to changes in water quality, and its leaves may turn yellow if water parameters are not maintained correctly. Regular water changes and maintaining ideal water conditions will promote healthy plant growth.
Fertilization
Hydrocotyle verticillata Thunb. var. triradiata (A. Rich.) Fern. benefits significantly from a nutrient-rich substrate. Fertilizers with a balanced proportion of macronutrients and micronutrients should be used regularly to maintain optimum growth. CO2 supplementation can also enhance plant growth and color density.
Over-fertilizing can lead to excessive algae growth and can cause damage to the plant. Adequate water changes and proper maintenance are necessary to maintain the balance of nutrients in the water.
Pruning
Hydrocotyle verticillata Thunb. var. triradiata (A. Rich.) Fern. has a fast growth rate and can become invasive if not pruned regularly. The plant can be trimmed back to desired lengths using scissors or pruning shears. It is essential to prune the plant before it becomes too tall, as the lower leaves will start to yellow and die off.
Pruning also enhances the plant's growth rate and promotes the growth of new stems. The trimmed portions can be replanted, and new, younger leaves will sprout from the stem's nodes.
Propagation of Hydrocotyle verticillata Thunb. var. triradiata (A. Rich.) Fern.
Hydrocotyle verticillata Thunb. var. triradiata (A. Rich.) Fern., commonly known as Whorled pennywort, can be propagated through multiple methods, including seed propagation and vegetative propagation.
Propagation by seeds
Seed propagation is a relatively easy way to propagate Hydrocotyle verticillata. Collect seeds from mature plants, which are easily obtained from the flowering stalks. Once collected, clean the seeds thoroughly, and sow them in a well-draining potting mix. Keep the soil consistently moist and at a temperature of around 72°F (22°C) until the seeds germinate, which should take around 2-3 weeks.
Vegetative Propagation
Hydrocotyle verticillata can also be propagated through vegetative propagation. This method involves the use of plant cuttings. Take cuttings from mature plants that have at least three healthy leaves on them. Cuttings should be around 2-3 inches long and should be taken from the tip of the stem. Place the cuttings in a well-draining potting mix, and make sure that the leaf nodes are in contact with the soil. Keep the soil moist, and add a layer of plastic wrap over the top to create humidity. After a few weeks, new growth should appear, which is a sign that the cuttings have rooted.
By using either one or both of these propagation methods, you will have no trouble expanding your collection or sharing your Hydrocotyle verticillata with fellow hobbyists or friends.
