How to care for orchids in winter? These key care points you need to master

Winterorchid carekey points briefly discussed!
Orchid care comes down to just a few points!
Water,
In winter avoid "wet"; "moist" is enough! For my granular medium cultivation, a thorough watering every 10-15 days; for New Zealandorchid plantsgrown in charcoal, basically water once every 20-30 days! After watering, please do not use a fan to blow air! Choose a day with relatively high temperature and ample sunlight to water! Prevent excessive water from damaging the roots!
Fertilizer,
In winterorchidsbasically do not need much fertilizer. Because of the low temperature,orchidshave already entered dormancy! If you are going to participate in an orchid show,orchidsneed to be "lifted from the pot"; it is recommended to use a small amount of "monopotassium phosphate" -- a 1:1200 solution to wrap the roots, which can effectively preserve the bloom quality!
Light.
For winterorchids,"supplemental lighting" is quite important! Although the orchid plants have entered dormancy, at an appropriate temperature, good light can still allow the orchid plants to effectively accumulate energy, nourish the pseudobulbs, and strengthen the autumn shoots and the upcoming spring shoots!
Temperature,
In winter, orchids had best not be heated. Why do people oppose "greenhouse plants"? What are "greenhouse plants"? -- In my humble opinion, they refer to orchid plants that are heated in winter!  Winter is a great time for orchid plants to rest and recuperate, accumulate energy, strengthen the pseudobulbs, and increase disease resistance. Blindly applying heat causes the orchid plants to "grow leggy." Although in the short term it achieves the goals of "producing more shoots" and "fast maturing of shoots," it reduces the disease resistance of the orchid plants! It is no different from "killing the goose that lays the golden eggs"! After fellow orchid growers introduce such plants, they are also very difficult to cultivate!
For varieties that require "vernalization," appropriate low temperatures are also needed!  
One point to note is the damage to orchid plants from frost, snow, and cold wind! In some places, orchids definitely need an orchid shed to overwinter!
Humidity,
In winter, humidity should not be too high! Generally around 30% is enough! Especially in low-temperature weather, humidity must not be too high, to prevent frost damage to the orchid plants!
Disease prevention and control,
Orchid diseases generally occur relatively rarely in winter! The real thing to watch out for is preventing "rats" from gnawing on orchid shoots and flower buds!
