1、 Fertilization season

Generally speaking, orchids mainly need fertilization when they grow very fast. The specific time is spring and autumn. Summer is an exception because the temperature is too high for fertilization. Low temperature in winter, plants basically do not grow, so there is no demand for fertilizer

2、 Fertilization requirements

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 state of the whole year. The fertilizer applied in autumn is different, which is the fertilizer to promote buds and strong seedlings. Timely fertilization, orchids will grow well and bloom more and better

2、 Precautions

1. The most important thing of fertilization is the concentration. It doesn't like too strong fertilizer. It needs to be diluted with water, and the water quality is also very important. Water must not contain impurities. Moreover, if tap water is used, it should be stored for one day and then reused when the chlorine gas is exhausted

2. If it is foliar fertilizer, pay attention to the parts sprayed, and spray more on the back. Stomata is the part where the plant connects with the outside world. The distribution of stomata in orchid leaves is uneven, with about 85% on the back and only about 15% on the front. Therefore, more fertilizer should be applied to the back when applying fertilizer
