The plant can be grown in a variety of environments, including aquariums, ponds, and outdoor water gardens. To cultivate Rotala rotunda A.Chev., you will need a suitable container or water garden, the right growing conditions, and a supply of nutrients to support growth.
In an aquarium or pond, it is best to keep the water temperature around 70°F to 80°F, with a pH ranging between 6.5 and 7.5. The plant needs plenty of sunlight, so it is important to ensure that it receives at least 6 to 8 hours of indirect light per day.
Watering Needs
As an aquatic plant, Rotala rotunda A.Chev. needs to be fully submerged in water. It requires a consistent water supply to thrive, so it is important to ensure that the water is clean and free from contamination.
The water should be changed regularly to prevent the build-up of harmful bacteria and algae. If you are growing the plant in an aquarium, you should aim to replace about 25% of the water every week. For outdoor water gardens, it may be necessary to change the water more frequently, especially during hot weather.
Fertilization
Rotala rotunda A.Chev. relies on a steady supply of nutrients to support growth. To encourage healthy growth and vibrant coloration, it is important to fertilize the plant regularly.
You can use a general aquarium or pond fertilizer to supply nutrients to the plant. Alternatively, you can use a specific aquatic plant fertilizer to meet the specific requirements of Rotala rotunda A.Chev.
It is important not to over-fertilize the plant, as this can lead to the build-up of harmful chemicals in the water. Follow the instructions on the fertilizer carefully.
Pruning
Rotala rotunda A.Chev. responds well to pruning and can be shaped in a variety of ways to suit your preferences.
To prune the plant, use a pair of sharp scissors to cut back the stems. It is best to remove no more than one-third of the plant at a time to avoid damaging the roots.
When pruning, it is also important to remove any dead or damaged leaves to maintain the overall health of the plant.
Propagation of Rotala rotunda A.Chev.
Rotala rotunda A.Chev. is a relatively easy plant to propagate and can be accomplished through several methods.
Cutting Propagation
One of the most popular methods for propagating Rotala rotunda A.Chev. is through stem cuttings. To do this, simply cut a healthy stem from the mother plant and remove the lower leaves, leaving only the top 2-4 leaves. Place the cutting in a substrate or in water and ensure that the leaves are above the waterline. After a few weeks, roots should begin to form at the base of the stem, indicating that the new plant is ready to be placed in its own container.
Division
If the mother plant of Rotala rotunda A.Chev. has multiple stems, you can gently separate these stems to get multiple individual plants. Dig out the entire plant with the roots and carefully divide the stems, taking care not to damage them. Trim the roots to a manageable size and replant each stem in a separate container.
Runners
Rotala rotunda A.Chev. can produce runners, which are new stems that grow out from the mother plant and eventually take root themselves. If you see runners developing, you can gently detach them from the mother plant and plant them separately. Be cautious not to damage the runner or roots in the process.
