1、 New root method

1. If it is said that the cultivated happy tree has rotten roots, it needs to regenerate new roots. First, remove the roots of the old plants from the pot with a shovel. Directly use a clean pair of scissors to cut off the rotten root system until it shows the healthy root system at the cutting edge. Disinfect and dry in potassium permanganate, apply some rooting powder and put it on the basin again, and finally wait for it to grow new roots

2. If cutting is carried out in winter to produce new roots, the temperature should be controlled above 15 ℃. If the temperature is too low, it will grow poorly. Cut branches with a length of 15-20cm from the mother plant, leaving only 2-3 leaves at the top. It is best to treat them with rooting solution and then cut them into flower soil. During its rooting, it should have a certain humidity and avoid strong light

2、 Winter watering method

Watering in winter must not be too diligent. It is best to check the dry and wet condition of the basin soil with a shovel before watering. If the soil is white, you can water it. Moreover, the water temperature should also be close to the room temperature. Too cold water will frostbite its roots. Watering should also be at noon as far as possible, and proper light and ventilation should be provided after watering
