4

Too much light. Orchids are sun-loving flowers, so don't put them in direct sunlight. .

5

The temperature is not good. Orchids thrive in warm environments. Cold or freezing temperatures in winter can cause orchids to die. Summer temperature is too high, orchids suffer from the heat, the base of the leaves begin to rot, will produce the phenomenon of dead leaves.

7

Air pollution. Orchids are very sensitive to air pollution, such as oil smoke, soot, paint, sand insect agents, etc., a little carelessness will cause orchids to die or even die.

8

Change pot change soil adaptation period. Changing POTS or soil can damage orchid roots. After re-planting, they did not adapt to it for a while, and the leaves did not absorb nutrients in time, so there will be drying phenomenon.

Step 2: Method
1

Water is the source of orchid life, is the root of orchid growth. Orchid watering as far as possible to see dry see wet, dry soil does not water, watering it through. Do not pour fresh tap water, rain is best. Water often in autumn, and the soil should not be too wet in winter.

Orchids grow slowly, generally require less fertilizer, and often use thin fertilizer application method. When orchids are thriving, fertilize them every 7 days. No fertilization every year when it is hot, cold and rainy.

Take care to regulate the temperature around the orchid.

6
