Flowers and leaves are warm, and the optimum growth temperature is 13- 18℃. Cold-resistant, can tolerate the low temperature of -5℃ in winter, but it is best to keep it above 0℃.

2. Lighting equipment

Flowers and leaves like light and are resistant to semi-shade. However, avoid strong sunlight. Under the condition of full light, plants grow poorly, become short, their leaves turn yellow and get burnt. May-September should be cool, or placed under a big tree and other semi-cool places. Sufficient scattered light can keep the leaves green and shiny. We should also avoid too much shading. When the light is insufficient, the leaves lack luster and the beautiful spots become dim, making it difficult to bloom.

water

Flowers and leaves are resistant to moisture, drought and moist soil environment. In the growing period, the water should be sufficient to keep the basin soil moist, but it should not be too wet and stagnant, otherwise it will lead to rotten roots. Water loss is faster in summer, so watering should be appropriate; In winter, we should control the amount of watering and keep the soil moist.

Step 4 apply fertilizer

More nutrients are needed in the growth period, so topdressing should be done every half month 1 time, and the coordination of nitrogen, phosphorus and potassium should be mastered in fertilization to make the plants grow strong and bright. Too much nitrogen fertilizer will make the leaves grow too fat and soft, prone to lodging, and make the spots of new leaves smaller or even completely green. Fertilization should be stopped in winter.

prune

Yellow leaves and old leaves that are not growing well should be cut off at any time.

Step 6 turn the washbasin over

Potted plants turn 1 time every spring, and ground plants need to be planted 1 time every 3-4 years. Don't choose soil, loose, fertile and well-drained soil is better; It can grow in slightly acidic to slightly alkaline soil with PH value of 5.5-8. The substrate can be made of humus soil, garden soil, chaff ash or coarse sand.
