1、 Sowing time

Considering the temperature of seed budding, it is generally appropriate to sow in March and April when the temperature returns to warm in spring, and the temperature can reach about 26

2、 Sowing method

1. Select a flowerpot with good air permeability and drainage performance, put in the nutrient soil, plant seeds, gently press it with your fingers or cover it with a thin layer of soil, spray water with a watering can to completely soak the soil, and often spray water on the basin surface to keep the basin soil moist. Place the flowerpot in a cool place to avoid rapid evaporation caused by direct sunlight, and keep the temperature at 23 ℃ to 29 ℃

2. If the temperature is in place, it can germinate in less than a month in 25 days. In summer, it is necessary to shade and place it in a semi shady place

3、 Later maintenance

1. Moisture

After the seedlings grow stably, they enter the growth period. When transplanting, it should be replaced with loose, fertile and well drained peat soil mixed with fine sandy soil. At this time, the water demand is relatively large. The water supply should be timely to ensure the moisture of the soil. When the temperature is too high in summer, it can be sprayed on the leaves. In order to avoid freezing in winter, we should reduce water

2. Temperature

Seedlings in the growth stage prefer a semi cloudy environment and cannot be directly exposed to sunlight. The temperature is about 23 ° C at room temperature. The temperature in winter should be kept at 5 to 8 ° C to ensure normal growth. For some special varieties, it should be more than 18 ° C

3. Topdressing

The fertilization season is mostly concentrated in the growth season of spring and autumn. Fertilization should be done once every half a month from May to October. If the leaves are abnormal in winter, it may also be the problem of insufficient fertility. Spray slow-release fertilizer

4. Pruning

After planting, the plants are basically formed. If the shape looks unsightly, you can repair it yourself. The cut branches can be inserted into water or the same soil, and new roots will be born
