What fertilizer is best for orchids?

Orchids are common ornamental flowers with graceful postures, green leaves and fresh flowers. Many friends of ours grow them. When fertilizing orchids, you must follow the principle of applying small amounts of fertilizer frequently. So what fertilizer is best for orchids? Let’s take a look with the editor below.

1. What fertilizer is best for orchids?

1. Organic fertilizer

Organic fertilizers contain nitrogen, phosphorus and potassium elements. Commonly used ones include cow dung fertilizer, chicken manure fertilizer and soybean cake fertilizer. They all need to be fully fermented, and after being decomposed, they are diluted with water to become a thin fertilizer liquid before being used for orchids. Regular watering can supplement nutrients for orchids. If you use cake fertilizer, you can add an appropriate amount of ordinary compound fertilizer to make the fertilizer liquid more comprehensive.

2. Special slow-release fertilizer

The slow-release fertilizer specially made for orchids is for lazy people only. It is easy to use, has a long-lasting and gentle fertilizer effect, and will not cause any harm to the roots of orchids and the tender shoots of the plants. Generally, the fertilizer effect can last for half a year after one use. It can effectively promote the growth and strength of orchid roots. Be careful not to use it excessively, otherwise it will cause root burn.

3. Water-soluble fertilizer

Common water-soluble fertilizers include the Huaduoduo series of water-soluble fertilizers and the Aolv series. These fertilizers can be diluted and used for root irrigation or sprayed on the leaves. It can be used as top dressing, is easy to use, and can be quickly absorbed by plants. Note that water-soluble fertilizers need to be diluted according to the ratio before use. If you want to irrigate the roots, you need to moisten the soil first and then water it, otherwise the potting soil will dry out and easily burn the seedlings.

2. How to fertilize orchids?

1. Spring and summer

Spring and summer are the germination period for orchids. You can apply germination fertilizer to promote the growth of new buds. It should be noted that you need to pay attention to the time of fertilization. It is best not to fertilize in the morning. You can choose to fertilize in the evening or in a dark place.

2. Autumn

Autumn is the growth period of orchids, and the plants consume a lot of nutrients and need to be replenished in time. When applying fertilizer, it is best to use phosphorus and potassium fertilizers as the main fertilizer and nitrogen fertilizers as the supplement. You can also spray some organic liquid fertilizers, which is beneficial to the growth of orchids.

3. Winter

It is cold in winter and orchids enter a dormant period. Fertilization should be reduced or stopped. Solid fertilizer can be applied before winter comes. This will help enhance the plant's cold resistance, allowing the plant to survive the winter smoothly and also prepare for the plant's later growth.

The above is an introduction to the best fertilizer for orchids. Orchids need to wait until the second year to be fertilized, which is beneficial to provide nutrients for the plants and promote flowering. When fertilizing, nitrogen fertilizer needs to be used before flowering, which is beneficial to the growth of flower buds. Phosphorus and potassium fertilizers can be applied after flowering, which is beneficial to timely replenishment of nutrients.
