Cultivation Methods
Orthosiphon laurentii De Wild., commonly known as the giant cat's whiskers, is a tropical plant that thrives in warm and humid conditions. It does best in loamy soils with good drainage and prefers partially shaded areas.
The plant can be propagated through seeds, cuttings, or division. Seedlings should be planted in small pots with well-draining soil and kept in a warm and humid environment until they grow into mature plants for planting.
Watering Needs
Orthosiphon laurentii De Wild. requires regular watering to maintain optimal growth and health. However, it is essential to ensure that the plant is not overwatered as it is susceptible to root rot.
Water the plant thoroughly but avoid waterlogging. Keep the soil moist but not wet and reduce watering during the winter months.
Fertilization
Regular fertilization is essential for the healthy growth of Orthosiphon laurentii De Wild. The plant requires a balanced fertilizer every two weeks during the growing season.
Organic fertilizers such as compost and manure provide necessary nutrients while also improving soil fertility and structure. Avoid over-fertilization as it can lead to the accumulation of salts in the soil, which can harm the plant.
Pruning
Pruning is necessary to maintain the shape and appearance of the Orthosiphon laurentii De Wild. Remove dead or damaged plant parts to prevent disease and pest infestation. Regular pruning also encourages the development of new growth.

Propagation of Orthosiphon laurentii De Wild.
Orthosiphon laurentii De Wild. can be propagated through different methods, such as:
Seed propagation
Orthosiphon laurentii De Wild. can be propagated through seeds. The seeds should be harvested from the plant when they are fully mature; they are usually ready for harvest in the autumn. The seeds should be sown in seed trays filled with a well-draining seed-starting mixture. They should then be covered with a thin layer of soil, watered, and kept in a warm and well-lit location. The seeds should germinate within two to three weeks.
Cuttings propagation
The plant can also be propagated through cuttings. Take stem cuttings from the plant during the spring or early summer. Cuttings are best taken from stems that have not yet flowered. Dip the cuttings in rooting hormone and plant them in small pots filled with a well-draining potting mixture. The cuttings should be kept in a warm and well-lit location, and their soil should be kept moist. Roots should start forming within four to six weeks. Transplant the rooted cuttings into larger pots or to the desired planting location.
Division propagation
Division propagation of Orthosiphon laurentii De Wild. can be done every few years or when the plant has grown too large for its container. Carefully remove the plant from its container, gently separate the root ball into two halves (or more), and then repot each half in its container or the desired planting location. Be sure to provide each plant with enough space to grow and maintain its shape.
