Watering Needs of Weihea Rotundifolia Engl.
The watering needs of Weihea rotundifolia Engl. are relatively low, and the soil should be kept slightly moist during the growing season. Ensure that the soil is not waterlogged as this can lead to root rot. Reduce watering during the winter months, when the plant's growth slows, allowing the soil to dry out slightly between watering times.
Fertilization of Weihea Rotundifolia Engl.
The plant will benefit from regular fertilization during the growing season. A well-balanced fertilizer should be used every two to three weeks to encourage healthy growth and flowering. During the winter months, fertilization should be reduced or stopped altogether.

Propagation of Weihea Rotundifolia Engl.
Propagation of Weihea Rotundifolia Engl. can be done through various methods. The following are some of the most common propagation methods for this plant:
Seed Propagation
This is a popular method of propagation for Weihea Rotundifolia Engl. Seeds should be collected from mature plants during the rainy season. The seeds should be sown in a mixture of soil and sand and kept moist. Once they germinate, the seedlings should be transplanted into individual pots and placed in a shaded area until they are strong enough for planting in the garden.
Cuttings Propagation
Cuttings can also be used to propagate Weihea Rotundifolia Engl. Cuttings should be taken from mature plants from the softwood section and planted in soil mixed with sand. The cuttings should be kept moist and shaded until they develop roots. Once the roots have formed, the cuttings can be transplanted into individual pots and placed in a shaded area until they are strong enough for planting in the garden.
Air Layering Propagation
Air layering is another method for propagating Weihea Rotundifolia Engl. This method involves wounding the stem of the plant by cutting off a small slice of bark to expose the inner tissue. The exposed section is then covered with sphagnum moss and wrapped in plastic wrap. The moss should be kept moist and in about two months, roots will appear. The rooted section can be cut from the mother plant and transplanted into a pot with soil.
Division Propagation
Propagation by division involves separating clumps of Weihea Rotundifolia Engl. and replanting them. Adult plants that have formed clumps can be divided into smaller sections and replanted. Before dividing, the plant should be watered thoroughly to reduce stress. The sections should be replanted in a soil and sand mixture and kept moist until they are established.
