The advantages of open-air cultivation: good light, good ventilation, fast heat dissipation. Disadvantages: the humidity in the rainy season is uncontrollable and diseases are easy to occur, so we should pay attention to the following problems:

1: timely spraying pesticides, such as Fusarium oxysporum, soft rot, which is most likely to occur in the rainy season, can be prevented and treated with poplar manganese, de Klee, streptomycin or Bordeaux solution.

2: the use of materials must be good drainage, basin spacing should not be too close, affecting ventilation, under the basin rack to keep dry, do not accumulate water, to avoid bacterial reproduction.

3: to prevent overgrowth, do not apply nitrogen fertilizer, and supplement phosphate fertilizer in the rainy season to make the plant more robust.

4: if diseased plants are found, they should be isolated immediately to avoid infection.

5: easy to dry in autumn, not easy to moisturize, leaves to replenish moisture, to avoid scorched tail. To prevent cold damage in winter, phosphate fertilizer should not be too high, a small amount of potash fertilizer should be added.
