1、 What is the reason why orchids don't bloom after long bud

1. Temperature discomfort: most orchids prefer a cold environment and are more likely to blossom at 15-20 ℃. If it is kept in a place too cold or hot for a long time, it will not bloom

2. Sick and insect: if the orchid is placed in a place with poor ventilation and is not well maintained, it will become sick or insect, then its flower bud will wither and cannot bloom normally

3. No vernalization: some orchid varieties with flowering period in winter and spring need vernalization treatment after the bud grows, that is, after low-temperature maintenance for a period of time, they can bloom smoothly. If they are kept in a warm place after they grow buds, they will not bloom

4. Excessive watering: if you don't control the water in time after the orchid grows its bud and often water it, it will hurt its root system and make it unable to bloom

2、 How can orchids bloom
