How to drench Phalaenopsis in Water
Phalaenopsis is an epiphytic orchid, which requires not only high air humidity, but also no stagnant water in the cultivation substrate, otherwise it is easy to cause plant rot and root death. After entering winter, it can be watered once a week, the time should be from 10:00 to 11:00, it is not suitable to water more in cold weather, in order to keep the cultivation substrate a little dry. Phalaenopsis should be kept in an environment of no less than 10 ℃ in winter, with certain light conditions. If the foliar spray is given, it is best to spray, so as not to form stagnant water in the center of the foliage. The spray can be carried out around noon, and the water temperature is required to be basically the same as the air temperature. after an afternoon of evaporation, the leaves have dried up and there are no more water droplets, which can be conducive to its overnight and safe winter. The rotten root of your Phalaenopsis has a lot to do with spraying too much water on the plant, resulting in more stagnant water in the leaf armpit at night, and the cultivation substrate is too wet. The suitable temperature for the growth of Phalaenopsis is 20 ℃ to 30 ℃, and a relatively warm environment should be created for Phalaenopsis in winter. If there is more water retention in the leaf armpit after foliar spraying, the water droplets can be absorbed away with towels or toilet paper and must not be taken lightly.

When the new roots grow, the old leaves near the base will turn brown and fall off, which is a normal phenomenon in autumn.
