1, if you don't do it, you will pour it thoroughly.
Don't do it, don't water it, which means you need to wait until the soil is completely dry before watering it, otherwise there is still a danger of root rot. You can insert bamboo sticks into the medium until the bottom of the basin. If there is moisture after taking them out, don't water them in a hurry. Unlike grass flowers, which are dry and wet, this is why I have repeatedly stressed that longevity is a succulent plant. Compared with other succulent plants, plants of Crassulaceae are more water-resistant, and it doesn't matter much if this principle is not fully implemented during the growing period, but it is better to strictly implement it in extreme weather. In addition, although there is no data to show that not watering is one of the prerequisites to ensure the longevity of plants, if you always like to keep the soil moist and the sunshine and ventilation are average, your longevity will probably be in vain, and the plants will become weak and unhealthy. In addition, pay attention to watering slowly with fine water after drying, and water it back and forth several times, because the gap between the medium and the basin is relatively large after drying, and the water will be lost quickly if it is poured fiercely, and most of the medium has not had time to absorb water. Pot immersion is not recommended because it is easy to infect root mealybug and accumulate water and alkali. The influence of media on plants is highlighted here. A good media can dry thoroughly within 1~2 days, and it will not harden, so that roots can get sufficient breathing and it is also beneficial to water infiltration.

2. Better dry than wet.
Normally, it should be watered more during the growth period, especially when flower buds are formed in autumn. It's cool to pour Ciel Phantomhive in severe winter, and water should be cut off when it continues to be higher than 35°C and lower than 8 C.. Especially in summer, people feel that the water in the soil will soon dry up, so frequent watering can easily lead to long-term wet roots and rot. In fact, the air humidity is high in summer, and the soil surface seems to be dry, but the bottom is still not dry, especially in the southern region. In cold winter, try to choose noon or afternoon watering with water temperature close to air temperature; When the cold wave reaches a sudden drop in temperature and it continues to be cold, it is not watered, even if the medium is dry and the leaves are wilted. Because rotten roots are irreversible, and leaves can recover quickly after watering as long as they are not very dehydrated. More than 95% of longevity is caused by water, rotten roots and rot rather than drought and thirst, so please remember to choose "no watering" when you are not sure whether you should water it.
