Generally speaking, when the outdoor temperature can reach about 10 ℃, and the temperature is relatively stable, it can be moved to the outdoor. Some flowers are very cold resistant, and the time to go out of the room can be a little earlier. April is more suitable. In the south, it will be a little warmer, so we can advance it properly. In the north, it will be colder, so we can postpone it for a while.
1. Adapt in advance: you can adapt before you leave the room, that is to say, when you are about 10-15 days before you leave the room, you should open more windows as much as possible, so that the plants can gradually accept the outdoor temperature. You can also move plants outside in the daytime and in the evening.
2. Proper entry: in some areas, there will be strong wind or late frost in spring. For such weather, you still need to move indoors again, and leave when the weather is stable.
3. Don't worry about fertilizing: when you just leave the room, don't worry about fertilizing it, especially don't apply concentrated fertilizer. It has not adapted to the new environment, the root system is still in the state of not absorbing nutrients, there will be fertilizer damage.
After leaving the room in spring, we need to wait for its root system to recover slowly. We need to water a little, and do not apply fertilizer first, wait for its root system to be normal, then apply thin fertilizer frequently.
