Orchids are a common indoor potted plant, loved by many. However, to ensure orchids grow healthily and vigorously, they must be provided with sufficient nutrients. Choosing the right fertilizer is therefore very important. This article will introduce how to make and use suitable fertilizer for orchids.
Orchids' Nutritional Requirements
Orchids require various elements for healthy growth. These elements include nitrogen, phosphorus, potassium, magnesium, iron, zinc, etc. A lack of any one of these will affect the growth of the orchid.
Choosing Fertilizer
Orchids are suitable for both organic and inorganic fertilizers, with a preference for organic fertilizers. Organic fertilizers can provide more comprehensive nutritional components, but they decompose slowly and take effect gradually; inorganic fertilizers, on the other hand, can quickly supplement the nutrients needed by orchids.
How to Make Organic Fertilizer
The method of making organic fertilizer is simple. You can use biomass such as kitchen waste and farming waste. First, chop these wastes, add an appropriate amount of microbial enzymes, mix them well, and then place them in a well-ventilated area. After a period of composting and fermentation, it will become organic fertilizer.
How to Use Organic Fertilizer
Spread the prepared organic fertilizer evenly on the surface of the orchid soil, then mix it in gently. It is recommended to use organic fertilizer once every three months.
Choosing Inorganic Fertilizer
The main inorganic fertilizers suitable for orchids are those high in potassium and phosphorus. Common ones include monopotassium phosphate, potassium sulfate, etc.
How to Use Inorganic Fertilizer
Dissolve the inorganic fertilizer in water thoroughly, then spray it on the leaves and flower buds of the orchid. It is recommended to use inorganic fertilizer once every two weeks.
Precautions
When using fertilizer, pay close attention to its concentration. Fertilizer solution that is too strong and thick may burn the roots of the orchid, leading to the death of the plant. When using fertilizer, it must be added according to the ratio on the instructions.
The Four Stages of Orchid Growth
The growth of an orchid is divided into four stages: dormancy, new growth, active growth, and flowering. Different stages require different fertilizer combinations, so you must select the appropriate fertilizer based on the characteristics of the orchid's growth stage.
Fertilizer Choice During Dormancy
After the orchid enters the dormant period, it does not need to be given too much fertilizer. You can choose fertilizers that contain trace elements and a variety of vitamins, such as compound fertilizers.
Fertilizer Choice During New Growth Period
The new growth period refers to when the orchid recovers from dormancy and begins to grow new leaves and roots. At this time, the orchid needs some high-nitrogen fertilizer to help it grow quickly.
Fertilizer Choice During Active Growth Period
The active growth period of an orchid requires a balanced fertilizer to meet its increasing nutritional needs. It is recommended to choose a compound fertilizer containing various elements such as phosphorus and potassium.
Fertilizer Choice During Flowering Period
When the orchid is flowering, you should choose fertilizers that are high in phosphorus and potassium. This can promote the growth of flower buds and flowering, increasing the ornamental value of the orchid.
Fertilizer and Water Combination
The combination of fertilizer and water is also very important. It is necessary to ensure sufficient watering after each fertilization to ensure that the fertilizer is fully absorbed by the plant.
Cleaning the Flower Pot
Regularly cleaning the flower pot can remove salts and impurities accumulated in the soil, making the growing environment for the orchid cleaner and healthier.
The right fertilizer is an important guarantee for the healthy growth of orchids. When using fertilizer, you should choose according to the growth stage of the orchid and the characteristics of the fertilizer. In addition, the combination of fertilizer and water is also very important. Only through scientific and reasonable fertilization methods can orchids grow strong and healthy.
