The method of changing Phalaenopsis pot

The substrate for planting Phalaenopsis requires good drainage and slightly water conservation, as well as ventilation and ventilation. Commonly used are tree fern root, water moss, bark, charcoal, coconut capsid and ceramsite and so on. No matter what kind of substrate you use, when the Phalaenopsis plant is too large and the air roots wind around each other, it is necessary to change the basin. The basin change should be carried out in the summer of the growing period, the method is to pour out the plant, remove the old cultivation substrate, cut off the aging and rotten air roots, and then put a layer of charcoal on the bottom of the new basin, put in the plant, fill in the new substrate, and compact and drench it. Generally speaking, the time to change the basin should depend on the cultivation substrate, such as water moss as a plant material for 1 ~ 2 years will rot, when the rot secretes extremely acidic substances, directly hurt the air root, at this time, if you do not change the basin in time, it will lead to root rot. Therefore, the pot should be changed once in 1 ~ 2 years with water moss or bark as substrate, once every 2 or 3 years with tree fern root or coconut shell, and it will not be a problem for those planted with ceramsite or charcoal to change pot for 3 ~ 5 years, but fertilizer should be applied more and less to make up for the lack of nutrients in these substrates.
