Changing pots of Phalaenopsis

1. Selection of basin: generally choose plain fired pottery basin or plastic basin, porous basin is better, shallow basin is suitable for breathability, basin height is better than basin diameter.

2. Selection of culture medium: Phalaenopsis is a typical epiphytic orchid, its root system is well developed, and the cultivation substrate must have the characteristics of looseness, ventilation, good air permeability and rot resistance. According to the author's cultivation experience, pine needles, peanut shells and bark shreds should be selected as substrates for Phalaenopsis cultivation in the north. The pot must be changed every year, if the pot is not changed in time, the rot of the pot substrate will cause contraction, poor air permeability, serious decline in the growth of orchid plants, and even death.

3. Time and method of changing pots: the best time for Phalaenopsis to change pots is in late spring and early summer, and the best temperature is above 20 ℃. At this time, just after flowering, new roots begin to grow. When changing the basin, first cut off the flower stem, gently remove the original nutrition bowl, dig out the lower part of the old matrix with fingers, cut off the dry old root, the rusty root, cut off the root, pad the basin bottom with broken tiles, put the sterilized wet pine needles into the basin floor first, put the roots of Phalaenopsis evenly into the basin, and then continue to put the pine needle leaves on the root system of the orchid plant, gently compacted so that the orchid plant stands firm. When planting, it should be noted that the rhizome of the orchid plant should be consistent with the height of the basin, and then spray water to put it in the indoor ventilation place, during this period, it is not suitable to apply fertilizer, only spraying water and proper watering are needed in management, leaf buds can grow after a month, and then carry out normal management.
