Strong light does no harm to plants. I like warm and humid climate and fertile and humid soil, and can resist slight salt, wind and moisture. The optimum growth temperature is 65438 0.5-30℃. Put it in a cold but not frozen room in winter. Pittosporum can tolerate freezing temperature, but in order to make it grow well, the low temperature at night should be kept above 65438 03℃. Pittosporum is drought-resistant. In summer, people consume a lot of water, so they should water it often. If the temperature is low in winter, the amount of watering should be reduced accordingly. The air humidity should be around 50%. Fertile soil is needed. Fertilize 1-2 times a month during the growing season, and no fertilization is needed at ordinary times. Young plants change pots every year, and adult plants change pots every 2-3 years. The basin is composed of 1/3 humus and 2/3 clay or loam. Strong germination and pruning resistance. It can be trimmed into various shapes every spring.

Garden use: In warm climate, this tree species is an ideal flower bed landscaping tree or landscaping tree, especially suitable for coastal planting. Do more houses, foundation planting, hedges. Plant potted plants in the north and use greenhouses in winter.

Pittosporum is easy to cultivate and does not need special management. Transplanting in the open field is usually carried out in March. If planted in autumn, it should be around 10. Before digging, the big seedlings must be tied with ropes to prevent the branches from breaking, and the soil balls must be brought when digging. The size of the soil ball depends on the thickness of the trunk. Seedlings can be transplanted with bare roots, but in time. Potted pittosporum is changed once a year in spring. When changing pots, the dead roots should be cut off and new culture soil with more organic matter should be added to the pot soil. Pittosporum has strong branching ability and is resistant to pruning It needs pruning and shaping in spring to keep a beautiful tree shape. If you want to inhibit its growth and make its branches and leaves multiply, you should cut off its top when it grows to a corresponding height. Others cut it into various forms. It can be placed outdoors in summer, and in the shade of flowers if possible. Strong light is harmless to plants. The air humidity is about 50%. The suitable growth temperature is 15 ~ 30℃, and it is not frozen in winter, and the low temperature is 5℃. Water consumption is high in summer, so water it frequently; If the temperature is low in winter, the amount of watering will be reduced accordingly.

Pittosporum potted plants can be made into various forms of bonsai through artistic processing. The upper basin should be planted in a deep basin, and a circle of hard plastic cloth with a height of 5 ~ 8 cm should be added to the upper part of the inner edge of the basin, and the bottom of the basin should be padded with broken tiles. The root can be raised correspondingly when the pot is put, and the pot soil is slightly lower than the plastic ring, so that deep pot shallow planting will not affect the survival. When new roots grow and branches and leaves are flourishing, remove the plastic ring. After that, the soil above the basin surface will be washed away by water and rain, so that the thick root system will be gradually exposed, which can achieve the purpose of hanging roots and exposing claws in advance and appearing quaint.
