Orchids what season fertilization best

Orchids fertilize best in spring and autumn. Neither high temperature nor low temperature season is suitable for fertilization. The fertilizer applied in spring is to promote the bud, which has a great impact on the growth of the whole year. Fertilizers applied in autumn can promote buds and strong seedlings. When applying fertilizer, pay attention to the concentration and water quality, try not to use insoluble fertilizer, and pay attention to the foliar fertilizer applied to the back of the leaf as far as possible.

First, the best season

Generally speaking, orchids are mainly fertilized when they are growing fast. Specifically, spring and autumn. Summer is an exception because the temperature is too high to apply fertilizer. Low temperature in winter, the plant is basically not long, so there is no demand. However, the fertilizer needed in these two seasons is not the same. Sprouting fertilizer is applied in spring. The fertilizer applied during this season is the most important and has an impact on growth throughout the year. The fertilizer applied in autumn is different, which is to promote buds and strong seedlings. With timely fertilization, the orchid will grow well and blossom more and better.

II. Points for attention

1. When it comes to fertilization, the most important thing is the concentration. Like other plants, orchids don't like too much fat. In addition, if you want to add water to dilute, water quality is also very important. The water must be clean and must not contain impurities. Moreover, if tap water is used, it should be stored for a day before the chlorine is used up.

2. Attention should also be paid to the types of fertilizers, which are not water-soluble.

3. If it is foliar fertilizer, pay attention to the place where it is sprayed. Stomata are the parts where the plant connects with the outside world. The stomatal distribution of orchid leaves is uneven, about 85% on the back and only about 15% on the front. Therefore, it is necessary to apply more fertilizer on the back.
