1、 Keep warm and control temperature

The cold tolerance of Pitaya seedlings is very poor, which is suitable for growing in an environment between 15 and 25 degrees. Once the temperature is lower than 10 degrees, it is prone to freezing injury. Therefore, the temperature should be controlled in winter, but it should not be too high. If it is higher than 25 degrees, it will also affect the growth. It is usually buried in the soil for heat preservation and antifreeze in winter

2、 Watering and moisturizing

It is relatively drought resistant. It doesn't need to be watered too often during maintenance. Moreover, it will hibernate at low temperature in winter, so it's more important to control water. But it is not without watering. If the water shortage is serious, it will also affect the later growth. Watering should be done a small amount and a few times to keep the soil in a semi dry and semi wet state

3、 Rational fertilization

It likes fertilizer itself. Proper fertilization in winter can make the plant stronger and increase cold resistance. However, it should be noted that the amount of fertilizer should not be too much and the concentration should not be too large. It should be carried out in a small amount for many times. The fertilizer should be diluted with potassium fertilizer

4、 Suitable light

It likes light very much, and the temperature in winter itself is low. It needs light more. It can improve the temperature and is conducive to winter. Therefore, during the maintenance period, it is necessary to put it in a place with good sun and get more sun exposure, so that it is easier to survive when transplanting in the later stage
