Light: Ludwigia sphaerocarpa Ell. var. deamii Fern. & Grisc. prefers moderate to high light exposure. Inadequate sunlight can lead to stunted growth.
Temperature: Ludwigia sphaerocarpa Ell. var. deamii Fern. & Grisc. is native to wetlands of the southeastern United States, where it prefers warm temperatures ranging from 68-86°F. It does not tolerate cold temperatures well.
Soil: Ludwigia sphaerocarpa Ell. var. deamii Fern. & Grisc. thrives in wet, boggy soils with high organic matter content. The soil should be acidic, with a pH of around 5.5-6.5, and well-drained to prevent waterlogging.
Nutrients: Ludwigia sphaerocarpa Ell. var. deamii Fern. & Grisc. requires regular fertilization to support healthy growth. A balanced liquid fertilizer or slow-release pellets can provide the necessary nutrients.
Water: Ludwigia sphaerocarpa Ell. var. deamii Fern. & Grisc. is an aquatic plant that requires constant access to water. The water should be clean, free of pollutants, and have a neutral to slightly acidic pH.
Cultivation Methods
Ludwigia sphaerocarpa Ell. var. deamii Fern. & Grisc. is a versatile plant and can be grown both submerged and emersed. It is advised to grow it in a nutrient-rich substrate with a pH range of 6.5 to 7.5.
The plant should be placed in an aquarium with a temperature range of 20 to 28°C and adequate lighting, with the light intensity not exceeding 0.5 watts per liter of water. If growing emersed, place it in a terrarium exposed to moderate to high light levels and 60-80% humidity.
Watering Needs
Typically, Ludwigia sphaerocarpa Ell. var. deamii Fern. & Grisc. requires a moderate amount of water to thrive. It would help if you watered it once a week, ensuring that the substrate is not entirely dry before watering. For submerged cultivation, the water level should be around 5 to 30 cm above the substrate.
The plant can tolerate a wide range of water conditions but prefers water hardness between 6 to 15 dGH and a pH range of 6.5 to 7.5.
Fertilization
The plant needs a regular supply of nutrients to grow well. It is recommended to dose the aquarium with a slow-release or liquid fertilizer rich in nitrogen, phosphorus, and potassium. For emersed cultivation, use a complete fertilizer with a balance of nitrogen, potassium, and phosphorus to support the growth of both roots and foliage.
You should follow the recommended dosage instructions of the fertilizer and adjust the dosage depending on the plant's growth and water conditions.
Pruning
Pruning is essential to maintain the plant's shape and overall health. Ludwigia sphaerocarpa Ell. var. deamii Fern. & Grisc. needs regular pruning to prevent overcrowding, which can lead to plant loss.
Trimming should be done using a pair of sharp scissors or pruning shears by cutting off the top of the stem to the desired height. It would be best to prune the plant regularly to encourage bushy growth and to maintain its overall appearance.
Propagation of Ludwigia sphaerocarpa Ell. var. deamii Fern. & Grisc.
Propagation of Ludwigia sphaerocarpa Ell. var. deamii Fern. & Grisc. can be achieved through two main methods:
1. Seed Propagation
Seeds of Ludwigia sphaerocarpa Ell. var. deamii Fern. & Grisc. can be sown directly in the soil during spring or summer. The seedlings will emerge after a few weeks. One thing to note is that the seeds should be covered lightly with soil, and the soil should be moist but not overly saturated.
Alternatively, seeds can be started indoors during winter, to be transplanted outdoors in spring. The seeds should be sown in a seed tray filled with a well-drained seed-starting mix. Place the tray under grow lights or in a sunny location and keep the soil moist. Transplant seedlings into individual pots when they are large enough to handle and plant them outside when the weather is right.
2. Vegetative Propagation
Vegetative propagation involves taking cuttings or offshoots from an established Ludwigia sphaerocarpa Ell. var. deamii Fern. & Grisc. plant and rooting them to form new plants. This method is useful when one is trying to propagate many plants and may not have enough seeds. The steps are as follows:
- Take a cutting from the parent plant that is at least four inches long. Cut cleanly with a sharp knife or scissors just below a node.
- Remove the leaves from the lower part of the cutting, leaving only two or three leaves at the top.
- Dip the cut end in rooting hormone powder or liquid, which will help it to produce roots quickly.
- Insert the cutting into a small pot filled with well-draining soil or a mix of soil and sand.
- Water the soil lightly and cover the pot with a plastic bag or a glass jar to help retain humidity and warmth that encourages root production.
- Place the pot in an area with bright, indirect light and keep the soil consistently moist, but not waterlogged.
- After a few weeks, the cutting will have rooted and started to grow new leaves. You can remove the plastic bag or jar and transplant the new plant to a larger pot or outside in the garden bed.
Overall, Ludwigia sphaerocarpa Ell. var. deamii Fern. & Grisc. can be propagated through seeds and vegetative methods such as stem cuttings. Choose the propagation method that suits you well and enjoy growing more of this beautiful plant!
