Grapefruit can not be planted in the open air in the north, because it needs a mild and warm growth environment, and the temperature needs to be stable at 16-21 ℃, while in the north, because of the cold climate, it is difficult to survive, it can grow in summer, but it will have problems in the winter, and it is difficult to bear fruit.
The soil is not suitable, it needs to grow in a place with rich water, and the climate in the north is dry. It is difficult to reach this condition in the open air, even if it survives, it can not bear fruit, so it is not recommended to plant in the open air environment in the North, and it can be planted indoors.
1. Temperature: it is difficult to adapt to the low temperature environment in the process of growth. Growth is slow below 0 ℃, and frost damage will occur below 5 ℃, so it is necessary to ensure good temperature conditions. General north winter has heating, can satisfy this condition, also want to notice not too close to heating equipment.
2. Pot soil: deep loam is needed for grapefruit growth. Soft soil should be selected to contain rich nutrients. Garden soil, pine needle and rotten leaf soil can be mixed
3. Moisture: it likes humid environment, so water supplement must be enough
