Watering Needs
The watering needs of Hoarea nivea Sweet are minimal, and it's best to keep the soil's moisture level slightly moist. Allow the top of the soil to dry out before watering again, as excess moisture can lead to root rot. Regular watering during the growing season will enhance blooming, and be cautious of over-watering.

Propagation of Hoarea nivea Sweet
Hoarea nivea Sweet is commonly known as the snowball bush or the Cape viburnum. It is a small shrub that belongs to the Caprifoliaceae family. Propagation of this plant can be done through seeds or stem cuttings.

Propagation of Hoarea nivea Sweet can also be done through stem cuttings. Take a 3-4 inch stem cutting from the plant, ensuring that it has a few leaves on it. Remove the lower leaves and dip the cutting in rooting hormone powder. Plant the cutting in a pot filled with well-draining soil and keep the soil moist. Cover the pot with a plastic bag to maintain humidity and place it in a warm area, away from direct sunlight. The cutting should root within a few weeks, and once it has developed roots, it can be transplanted into an individual pot.

Root and Stem Rot: This disease is caused by waterlogging and poor drainage of the soil. It leads to the rotting of the roots and stem of the plant, causing the plant to wilt and eventually die. To manage this disease, ensure proper drainage of the soil, avoid over-watering the plant, and use a well-draining potting mix.
Leaf Spot: This disease is caused by bacteria or fungi. It leads to the development of small spots on the leaves of the plant, which may later merge into bigger blotches. To manage this disease, remove any infected leaves and avoid splashing water on the leaves during watering.
Powdery Mildew: This disease is caused by fungal growth and is characterized by the development of a powdery white substance on the leaves of the plant. To manage this disease, use a fungicide, ensure proper air circulation around the plant, and prune the plant regularly to remove any infected leaves.
Common Pests
Spider Mites: These pests are tiny and can cause significant damage to the plant. They suck sap from the leaves, leading to yellowing and wilting. To manage spider mites, use a miticide, increase humidity around the plant, and avoid over-fertilizing the plant.
Mealybugs: These pests are soft-bodied and covered with a white, powdery substance. They feed on the sap of the plant, leading to yellowing and curling of the leaves. To manage mealybugs, remove any infected leaves, use a neem oil spray, and avoid over-watering the plant.
Scale Insects: These pests are small and covered with a hard, waxy shell. They suck sap from the leaves, leading to stunted growth and yellowing of the plant. To manage scale insects, use a horticultural oil, prune the plant regularly to remove the affected parts, and avoid over-fertilizing the plant.
