Watering needs
The watering needs of Lotus junceus (Benth.) Greene var. biolettii (Greene) Ottley vary depending on the growing conditions. When grown in sandy or rocky soil, the plant might require regular watering to prevent drought stress. However, when planted in well-drained soil, minimal watering is needed as overwatering can cause root rot.
One way to determine when to water your plant is to check the topsoil's moisture level. Water the plant when the topsoil is dry to touch.
Fertilization
The Lotus junceus (Benth.) Greene var. biolettii (Greene) Ottley plant has minimal fertilizer requirements. Too much fertilizer can cause the plant to grow excessively, leading to sprawling branches that could interfere with other plants.
However, you can apply a balanced, slow-release fertilizer with an NPK ratio of 10-10-10 during the growing season (spring to fall) to give the plant a nutrient boost.
Pruning
Pruning Lotus junceus (Benth.) Greene var. biolettii (Greene) Ottley involves removing dead, damaged, or diseased stems. This helps maintain the plant's overall health and appearance.
Pruning should be done during the plant's dormancy period, usually in late winter or early spring. You can also deadhead spent flowers to encourage new blooms.
However, take care not to prune the plant excessively, as it can cause stunted growth or even kill the plant.

Greene var. biolettii (Greene) Ottley, commonly known as biolleti's trefoil or wiregrass lotus, is a small, herbaceous perennial plant with slender, wire-like stem and small, yellow flowers. Propagation of this plant can be done through several methods, including seed propagation, division, and stem cuttings.
Seed propagation
Seeds of Lotus junceus var. biolettii can be collected in the fall, when the seedpods dry and begin to split open. The seeds can be sown immediately in trays filled with a sterile, well-draining soil mix. The trays should be kept moist and placed in a warm, sunny location.

The divisions can be replanted immediately in a well-prepared bed with plenty of organic matter.
Stem cuttings
Stem cuttings of Lotus junceus var. biolettii can be taken in the spring or early summer when the plant is actively growing. Cuttings should be taken from the tips of the stems and should be about 6 inches long. Remove the lower leaves and dip the cut end in rooting hormone. Insert the cutting into a well-drained potting mix and keep it moist. Roots should develop within 4 to 6 weeks.
Disease Management
The plant Lotus junceus (Benth.) Greene var. biolettii (Greene) Ottley is generally resistant to most plant diseases. However, it is still susceptible to some common plant diseases such as powdery mildew, and rust.
To manage powdery mildew, avoid watering the plant from above and ensure proper ventilation around the plant. In case of severe infection, treat the plant with fungicides such as copper-based solutions, sulfur-based solutions or neem oil-based solutions. To manage rust, remove and destroy all infected plant parts, and apply fungicides as necessary.
Pest Management
