Why do new orchid shoots die back? How to prevent and treat it

The main reasons for new shoots dying back: 
growing orchidsfor a year, with new growth in one spring, only to see the new shoots die back - the sight is truly unbearable. Not only is a whole year of growing wasted, but it also affects the next year's shoot growth. So I feel it is necessary to once again focus on analyzing the main reasons for new shoots dying back for friends new to orchid growing, and offer this as a modest contribution.

orchidThe reasons for shoot dieback come down to three:
1. Fungal disease: As spring returns to the earth and all things awaken,orchid plantsgrow wildly, and bacteria are not ones to be left out either. Fungal disease is the foremost cause of shoot dieback, with leaf rot being the worst, mostly starting from the growth point at the heart of the plant. By the time symptoms appear, it is already too late. The main cause is water droplets falling into the tender shoots and insufficient ventilation. Therefore, ventilation on all sides is essential, and being careful and meticulous everywhere is the strategy - water carefully, promptly wipe dry any water droplets on the new shoots, ventilate, and regularly apply fungicide as prevention.

2. Pest damage: Borer insects relish the sweetness of tender shoots at the plant's heart. They burrow into orchid shoots and wreak havoc. Normally it is very hard to notice anything unusual, and then one day the whole plant suddenly withers - that is the work of pests. Moreover, pest damage is inevitably linked to fungal disease, just as a wound on a person is prone to infection. Therefore, from mid-to-late March onward, orchid plants need insecticide and sterilization treatment. Xiaobaiyao (small white pills) works well, but it is toxic to humans and livestock. When using it, take care to work with your back to the wind, and be extremely careful to prevent children from accidentally ingesting it!

3. Human damage: New orchid friends care deeply for their orchids, longing for the plants to grow every day, moving the orchids around daily, or frequently fertilizing or watering and misting from time to time, and some even try to help the shoots grow by pulling on them, or dividing plants during the sprouting season to get more shoots, and so on. In fact, fertilizing is just the icing on the cake, for producing better and more shoots. If new orchid friends find it hard to grasp the nature and concentration of fertilizer for the time being, it does no harm to skip fertilizing orchids that have just been repotted for a full year. Or applying a weak foliar feed is also quite effective. There are no orchids that starve to death, only orchids that die from over-fertilizing - new orchid friends must remember this. Now

atthe approach of early summer, the temperature is not yet too high and the air humidity is still acceptable. Orchid friends need not mist their orchids at all - unless it is the dog days of summer, feel free to be lazy. Once the new shoots are growing, by all means do not divide the plants, otherwise it does harm and no good.
