Care Guide
How to Water
Keep the soil consistently moist but never waterlogged. Water when the top centimeter of soil feels dry. Use room-temperature water to avoid shocking the roots. Good drainage is essential to prevent root rot.
Lighting
Place in bright, indirect light near an east- or south-facing window. Avoid direct midday sun which can scorch the delicate leaves and flowers. A few hours of gentle morning sun is ideal.
Ideal Soil
Use a well-draining, slightly acidic mix of peat moss and perlite with a pH of 5.0-5.5. The soil should retain moisture without becoming soggy. An African violet potting mix works well.
Recommended Pot
Use a small to medium plastic or glazed ceramic pot with drainage holes. Plastic pots help retain moisture which this plant prefers. Avoid terracotta which dries out too quickly.

How to Propagate
Seed propagation
Seeds are extremely fine. Mix with sand for more even distribution. Bottom heat helps germination.
- 1 Sprinkle tiny seeds on the surface of moist seed-starting mix
- 2 Do not cover seeds as they need light to germinate
- 3 Cover the container with a humidity dome or plastic wrap
- 4 Maintain temperature between 22-26°C
- 5 Mist gently to keep soil moist
- 6 Remove cover once seedlings emerge after 2-3 weeks
Materials needed:
Stem tip cuttings
Use clean, sharp scissors. Maintain consistent moisture and warmth for best results.
- 1 Take 8-10 cm stem tip cuttings with at least two nodes
- 2 Remove the lower leaves
- 3 Dip the cut end in rooting hormone
- 4 Insert into a moist mix of peat and perlite
- 5 Cover with a plastic bag to maintain humidity
- 6 Place in bright indirect light and keep warm

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.
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.
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.
Whiteflies
Whiteflies are small, soft-bodied, winged insects closely related to aphids and mealybugs. They are moth-like in appearance, about 1/16 inch long, triangular in shape, and gray-white in color. These sap-sucking pests feed on plant tissue, causing yellowing, stunted growth, and wilting. They also excrete honeydew, which attracts ants and promotes sooty mold growth. Whiteflies can transmit serious plant viruses.
