Generally speaking, orchids need to be fertilized when they are growing rapidly. The specific time is spring and autumn. Summer is an exception because the temperature is too high for fertilization. Winter low temperature, the plant does not grow, so there is no need for fertilizer
The fertilizer applied in spring is bud promoting fertilizer. The fertilizer applied in this season is the most important, which has an impact on the growth of the whole year. The fertilizer applied in autumn is different, which can promote buds and strengthen seedlings. Timely fertilization, the growth of orchids will be good, flowering and good.
1. The most important thing for fertilization is the concentration. It doesn't like too thick fertilizer. It needs to be diluted with water. The water quality is also very important. Be sure to clean the water without impurities. Moreover, if tap water is used, it should be stored for one day before chlorine is used up.
2. If it is foliar fertilizer, pay attention to the parts sprayed, and spray more on the back. Stomata are the parts of plants that connect with the outside world. The distribution of stomata in orchid leaves is uneven, with 85% on the back and 15% on the front. Therefore, when fertilizing, we should apply more to the back.
