Doubanlan has average water resistance, so it should not be watered too much during the maintenance process and should not accumulate water. When the soil surface is dry, just pour a small amount of water to moisten the pot surface. In summer, the pots are generally moistened every other day and watered thoroughly twice a month. In autumn, the pots are moistened twice a week and watered thoroughly once a month. Control the amount of water in winter and moisten the basin once a week. The growth of
requires a long photoperiod, proper shading in summer and autumn, and no shading in winter and spring. Insufficient light may cause the watercress to bloom less easily, so you need to pull the watercress out and dry it in the sun more often.
likes warm winters and cool summers. The optimal growth temperature is 15-28°C. You don’t need to pay too much attention to the temperature in spring and autumn. In summer, when the temperature exceeds 35°C, it grows slowly. It can be cooled by shading and spraying. In winter, when the temperature is lower than 10°C, it needs to be moved indoors to prevent frostbite. The suitable air humidity is 70-80%, and the suitable humidity in winter is 50-60%.
The cultivation medium is rich in nutrients, so there is no need to apply chemical fertilizers during the cultivation process. Mixing an appropriate amount of cake fertilizer or sheep manure during the annual potting or soil replacement process can provide sufficient nutrients for the watercress. Generally, no fertilizer is applied in the middle.
A well-ventilated environment promotes the respiration of orchid plants, accelerates metabolism and promotes growth; if the ventilation conditions are poor, it is easy to cause bacteria and mold to multiply in large numbers, causing rot and mildew, which is not conducive to the growth of orchids .
