The specific steps to fertilize an orchid are as follows:

One: rotten farm fertilizer. Poultry manure is a particularly good nourishment for orchids, but it should be noted that this manure must be fermented for more than a year, otherwise the smell will not dissipate and the roots will burn.

Two: organic fertilizer for plants. If you have the energy and time, you can consider fermenting the leftover peels, vegetable leaves, or leaves and grass from the kitchen into nutrients.

Three: wheat straw and other dry digging such as machine fertilizer. The organic fertilizer that we usually use to plant fruit trees to ferment straw and wheat straw can also be provided to orchids for early distribution, which is not only recycled, but also ensures the ecological environment.

Four: the use of sugarcane straw. Leftover sugarcane and out-of-season sugarcane can be fermented, and the fertilizer used for sugarcane fermentation is very clean, and it has a particularly good ecological safety and composting effect.

Five: How to fertilize orchids. If you apply organic fertilizer once every half a month, you need to water it once after applying fertilizer, and if you use organic nutrient solution, you don't start it once a week, and dilute it 500 times.

Six: The foliar surface should also be fertilized. The purpose of fertilizing the foliar surface is to make the orchid grow better and faster, and the flowers will be more vigorous, using a thousand-fold solution of organic nutrient solution.

Seven: the situation that can not be fertilized. When the orchid grows unhealthy, such as the leaves are yellow and withered, or the growth is too sparse, it is necessary to rule out the orchid disease first.
