4、 Shading and heat preservation

The green pineapple after transplanting should be maintained for a period of time. During this period of time, it should not be exposed to direct sunlight, and the temperature should be kept above 20 degrees Celsius, so as to grow normally. After it grows new roots, it can be cultivated in the sun

5、 Suitable water and fertilizer
