Cultivation
Lotus glinoides Delile var. tuberculatus Sauvage, commonly known as Egyptian bean or tubercled lotus, is a perennial aquatic plant native to Africa. To cultivate this plant, you will need a clean pond or tank with a depth of at least one foot, filled with a mixture of loam and clay soils. Plant the tubercled lotus rhizomes in the soil bed medium and submerge in shallow water, ensuring that the crown is no more than 2 inches below the surface.
Place the container in a spot that receives full sunlight and maintain a water temperature of around 70°F to 75°F. This plant thrives in warm climates and grows optimally in conditions of high light intensity and warm water temperatures. Late spring to early summer is the best time to plant this species.
Watering
Tubercled lotus plants require a lot of water to grow, and adequate watering is one of the critical factors in ensuring healthy plant growth. Maintain a water depth of around one to two feet to prevent the plant from drying out. Ensure that the water in the container is stagnant and not running water to avoid uprooting of the plant from the container. You can top up the water as necessary to maintain the required water levels.
Fertilization
For optimal plant growth, you can fertilize the tubercled lotus plants using a liquid fertilizer. Apply the fertilizer once every two weeks, during the growing season. During the dormant season, you can reduce this frequency to about once a month. Ensure that the water is well-aerated before applying the fertilizer to ensure that the nutrients are absorbed by the plants efficiently.
Pruning
Pruning is essential in controlling the growth of the tubercled lotus plant. You can remove any dead or diseased leaves or stems as soon as you notice them. Cut them off as close to the base of the plant as possible using a sharp pair of scissors or pruning shears. You can also trim the plant as necessary to control its size and prevent it from overpowering other aquatic plants in the container.
Propagation of Lotus glinoides Delile var. tuberculatus Sauvage
Lotus glinoides Delile var. tuberculatus Sauvage, commonly known as the tubercled bird's foot trefoil, is a perennial herbaceous plant that belongs to the Fabaceae family. Propagation of this plant can be done in different ways, including:
Seed Propagation
Propagating the tubercled bird's foot trefoil from seed is very easy and the most commonly used method. The seeds should be sown in a well-draining soil mixture and watered regularly. It is recommended to soak the seeds for 24 hours before planting to increase germination rates. The perfect time to sow the seeds is in early spring or late fall. Once the seedlings have emerged, they should be transplanted to individual pots or to their permanent outdoor location when they have reached the size of 3 to 4 inches tall.
Vegetative Propagation
Vegetative propagation is another method for propagating Lotus glinoides Delile var. tuberculatus Sauvage. This method is mostly used where one wants to maintain plant characteristics and traits, or where the production of seed is limited. Rhizome division is the most common form of vegetative propagation for this plant. The separation of the rhizomes should be done in the spring when new growth has started. The rhizomes should be cut into pieces with at least one shoot or bud. These pieces should then be planted into well-draining soil with a spacing of about 6 to 8 inches apart.
Cutting Propagation
Cutting propagation involves the use of stem cuttings to produce new plants. For Lotus glinoides Delile var. tuberculatus Sauvage, this method is less common and may result in low success rates and is not recommended for beginners. The stem cuttings should be taken during the plant's active growth and should be at least 4 inches long. The bottom half of the cutting should be dipped in rooting hormone and planted in a rooting medium. Keep the medium moist and warm and away from direct sunlight until the cutting has developed roots and is ready to be transplanted to its permanent location.
Disease and Pest Management for Lotus glinoides Delile var. tuberculatus Sauvage

However, like any other plant, it is susceptible to various diseases and pests that can affect its growth and productivity. Here are some common diseases and pests of Lotus glinoides and how to manage them:
Diseases
Brown spot: Brown spot is a fungal disease that affects the leaves of the plant and causes brown lesions or spots. This disease can lead to defoliation and reduced plant growth. To manage brown spot, you can apply fungicides to the leaves of the plant. Additionally, you can avoid overhead irrigation and keep the area around the plant free from debris to prevent the disease from spreading.
Rust: Rust is a fungal disease that causes orange or brownish spots on the leaves of the plant. Severe infections can lead to defoliation, stunted growth, and reduced yield. To manage rust, you can prune and remove affected leaves, improve air circulation by planting the plants at appropriate distance, and apply fungicides to the remaining leaves.
Viruses: Lotus glinoides is susceptible to several viruses such as Bean yellow mosaic virus, Alfalfa mosaic virus, and Bean golden mosaic virus, among others. These viruses can cause stunted growth, yellowing and crinkling of leaves, reduced yield and even plant death. There is no cure to plant viruses, so the best management practices include planting resistant varieties, controlling weeds and insect vectors, and removing and destroying infected plants immediately to prevent spread.
Pests
Aphids: Aphids are small, soft-bodied insects that suck the sap of plants and excrete honeydew, which can attract ants and cause fungal infections on the plant. They can cause stunted growth, yellowing of leaves, and distorted shoots. To manage aphids, you can release natural predators such as ladybugs and lacewings, or apply insecticidal soap or neem oil to the plants.
Thrips: Thrips are tiny insects that feed on the plant's leaves and flowers, causing curling and distortion of leaves and discoloration of flowers. They also spread plant viruses. To manage thrips, you can apply insecticidal soap or horticultural oil, or prune and remove infected parts of the plant immediately.
Whiteflies: Whiteflies are tiny insects that suck sap from the leaves of plants and secrete honeydew, causing yellowing and death of the leaves. They also spread plant viruses.
