When is the best season to fertilize orchids?

1. Fertilization season

Generally speaking, orchids mainly need to be fertilized when their growth rate is very fast, which is in spring and fall. Summer is an exception because the temperature is too high to apply fertilizer. Due to the low temperatures in winter, the plants basically do not grow, so there is no need for fertilizer.

2. Fertilization requirements

The fertilizer applied in spring is bud-promoting fertilizer. The fertilizer applied in this season is the most important and has an impact on the growth status throughout the year. The fertilizer applied in autumn is different, it is fertilizer to promote budding and strengthen seedlings. If you apply fertilizer at the right time, orchids will grow well and bloom more and better.

2. Precautions

1. The most important thing about fertilizing is concentration. It does not like fertilizer that is too concentrated. It needs to be diluted with water. Water quality is also very important. The water must be clean and free of impurities. Also, if you use tap water, you should store it for a day to allow the chlorine to dissipate before using it.

2. If it is foliar fertilizer, pay attention to the area to be sprayed and spray more on the back. Stomata are the parts that connect the plant to the outside world. The stomata on orchid leaves are unevenly distributed, with about 85 percent on the back and only about 15 percent on the front. Therefore, when applying fertilizer, more fertilizer should be applied to the back.
