1. illumination: Poplar bonsai likes light, so get as much sunshine as possible. It is recommended to put it in a well-lit place, preferably in the morning light. The more sunlight, the more nutrients accumulated, which is more conducive to growth.

2, watering: water it according to the season, generally once every two or three days in spring and autumn, once a day in summer with high temperature and fast water loss, and once a week with low temperature and slow growth in winter. No matter what season you water, don't let water accumulate in the soil.

3. Fertilization: A lot of nutrients are needed in the peak season, and topdressing should be done in time. Only topdressing liquid fertilizer once every two months. Be careful not to apply topdressing to the roots, but to the edge of the flowerpot.

4. Temperature control: Pay attention to the high temperature in summer and the low temperature in winter. If the temperature exceeds 30 degrees in summer, it is necessary to strengthen ventilation and spray water frequently. In winter, the temperature is low. When the temperature is lower than 5 degrees, the temperature should be raised and moved to a warm place, preferably above 10 degrees, so as to spend summer and winter better.
