1、 Outlet temperature

Generally speaking, when the outdoor temperature can reach about 10 ℃ and the temperature is relatively stable, it can be moved outdoors for breeding. Some flowers are very resistant to the cold. They can leave the room a little earlier. It is more suitable around April. If the southern region will be slightly warmer, it can be appropriately advanced; In the north, it will be colder, so it can be postponed for a period of time

2、 Pay attention when you leave the room in spring

1. Adapt in advance: you can adapt in advance before going out of the room, that is, open more windows as much as possible 10-15 days before going out of the room, so that the plants can gradually accept the outdoor temperature. You can also move plants outdoors during the day and in at night

2. Proper entry: there will be strong wind or late frost in spring in some areas. For such weather, you still need to move indoors again and leave the room when the weather is stable

3. Don't rush to fertilize: when you first leave the room, don't rush to fertilize it, especially don't apply thick fertilizer. It has not adapted to the new environment, and the root system is still in a state where it can not absorb nutrients, which will lead to fertilizer damage

3、 Out of room maintenance

After leaving the room in spring, we need to wait for its root system to recover slowly. We should water it a little and do not apply fertilizer first. After its root system is normal, we can apply thin fertilizer frequently
