🔖 Care Tips
This plant is prone to pests and diseases. It's advisable to use fungicides and insecticides in April, May, around the rainy season, and in September for prevention. Additionally, if the leaves touch the ground, they are more susceptible to pests and diseases, so prune them if necessary.
🏝️ Habitat Conditions
This plant thrives in temperate regions of the Northern Hemisphere. It grows well in areas with plenty of sunlight and good drainage.
🪨 Soil Mix
When planting in the yard, it's important to ensure proper drainage. If the soil feels damp when you dig, it might have poor drainage. In such cases, dig a deep and wide hole and fill it with well-draining soil. However, it's best to plant in well-draining soil from the start. Well-draining soil is very beneficial for plants. A typical soil mix consists of 40% potting soil, 20% bark, 20% leaf mold, 10% perlite, and 10% humus, but this can vary depending on the situation and environment.
🌡️ Environment
Daytime temperatures should be 24-26°C, and nighttime temperatures should be 16-18°C. If it exceeds 30°C, flower stalks may not grow well, preventing blooming. Maintain humidity at 50-80%. Set it to 50-60% during the day and 70-80% at night. Ensure good air circulation to prevent mold, which can occur if humidity is high and air does not circulate well.

☀️ Light
Plants grow better with more light. Without enough light, it is difficult for them to grow healthily.
💧 Water
In summer, water the plant when the surface soil is dry. In winter, water when the inner soil is dry. It's best to water in the morning. The amount of water needed may vary by species, but if the plant blooms in summer, it requires more water. Be careful not to get water on the flowers, as they can easily be damaged.
🌱 Propagate
It is common to propagate by cutting stems about 10-20 cm long. For propagation: 1. If using water propagation, avoid transparent containers. Place the stem in water, and once roots appear, add hydroponic fertilizer. When roots are 5-7 cm or longer, transfer to soil. 2. For soil propagation, plant deeply in soil without fertilizer. After propagation, avoid exposing the plant to bright light. Gradually increase light exposure to help it adapt to gentle light. Maintain high humidity and keep the temperature between 18-22°C.
🪴 Repot
Repot in spring every 1-2 years due to its relatively fast growth rate.
💊 Fertilize
During spring and summer, when plants need a lot of nutrients to bloom, using fertilizer according to the recommended amount can promote vigorous growth. It is best not to fertilize during the dormant winter period.
🌺 Flower
After the flowers have bloomed, it is advisable to remove the flower stalks. Pruning should be done at least once in both spring and fall. Without pruning, the plant may not bloom abundantly. The flowering period is from May to June, with the flowers starting to bloom in May and reaching full bloom in June, when they are most beautiful.
😵 Toxicity
Non-toxic and safe for pets and children. Be cautious with species that have thorns, as they can cause injury.
