Care Guide
How to Water
Water every 3-4 days in summer, reducing to once a week in winter. Keep the rootball consistently moist but never soggy. Use lime-free, room-temperature water. Check soil moisture daily during the growing season.
Lighting
Provide bright, indirect light for at least 6-8 hours daily. An east or west-facing window is ideal indoors. Protect from harsh midday sun to prevent leaf burn. Supplement with grow lights (12 hours/day) if natural light is insufficient.
Ideal Soil
Use well-draining bonsai soil or a mix of equal parts akadama, pumice, and organic matter. Slightly acidic soil (pH 4.5-6.5) is preferred. Good drainage is critical to prevent root rot.
Recommended Pot
A shallow, unglazed ceramic bonsai pot with excellent drainage holes is ideal for Serissa. The pot should be proportional to the tree, typically about two-thirds the height of the tree. Neutral or earth-toned glazed pots also complement its delicate white flowers.

Common Problems
Root Rot
Root rot is a serious fungal disease that affects the root system of plants, causing them to decay and die. It is primarily caused by overwatering, poor drainage, or soil-borne fungi such as Pythium, Phytophthora, Rhizoctonia, and Fusarium. The disease thrives in waterlogged conditions where roots are deprived of oxygen, making them susceptible to fungal infection.
Spider Mites
Spider mites are tiny arachnids (less than 1/20 inch long) related to spiders and ticks that feed on plant sap. They thrive in hot, dry conditions and can cause significant damage to ornamental and vegetable plants. During severe infestations, crop losses can reach 14% or higher as these pests disrupt vital plant processes including photosynthesis, carbon dioxide absorption, and transpiration.
Aphids
Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.
Scale Insects
Scale insects are small sap-sucking pests that appear as brown, shell-like bumps on plant stems and leaves. There are over 25 species, divided into armored (hard) and unarmored (soft) scales. They feed by piercing plant tissue and extracting sap, which weakens the plant and can lead to yellowing, stunted growth, and even death if left untreated. They also excrete honeydew, which attracts ants and promotes sooty mold growth.
Meaning & Symbolism
In Japanese bonsai tradition, Serissa foetida symbolizes purity, perseverance, and delicate beauty. Its tiny star-shaped flowers represent countless blessings and the transience of beauty.
Fun Facts
Serissa foetida belongs to the Rubiaceae family, the same family as coffee plants.
Its species name 'foetida' means 'foul-smelling' in Latin, referring to the unpleasant odor released when its leaves or bark are bruised.
A healthy Serissa can produce hundreds of tiny star-shaped flowers simultaneously, which is why it earned the name Tree of a Thousand Stars.
In bonsai, Serissa is considered one of the most challenging indoor trees but also one of the most rewarding when properly cared for.
