Is compound fertilizer effective for orchids? How to apply compound fertilizer

1. Is it effective?

Applying compound fertilizer is very effective for orchids. Because orchids cannot grow without nitrogen fertilizer, cannot bloom without phosphorus fertilizer, and need potassium fertilizer for strong seedlings, it is appropriate to apply compound fertilizer to orchids. The compound fertilizer has a balanced ratio of nitrogen, phosphorus and potassium and contains sufficient nutrients, which can better promote plant growth. However, if you want to grow orchids well, it is best not to apply compound fertilizer alone. You can mix different fertilizers such as organic fertilizer and compound fertilizer, and apply different types of fertilizers according to the different growth stages of orchids. This will provide targeted nutrients to the plants and allow the orchids to grow better. In addition, when fertilizing orchids, remember to apply small amounts of fertilizer frequently. It is afraid of strong fertilizer, and prefers light to strong, and less to more.

2. Usage

1. Time: Phosphorus-potassium compound fertilizer can be applied during the growth process of orchids when they need to take root, grow leaves and promote flower bud differentiation. When entering the flower bud differentiation period, slow-release compound fertilizer can be used. To promote the growth of flower buds and increase the plant's ability to resist cold in autumn, you can mix some compound fertilizer when applying organic fertilizer. It is best to apply fertilizer in the evening every day so that the plants can fully absorb nutrients.

2. Method: The principle of fertilizing orchids is "apply thin fertilizer frequently, and prefer light fertilizer to heavy fertilizer." Therefore, when applying nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer and other compound fertilizers, they need to be diluted 100-1000 times before watering orchids. When watering the plants, you cannot use fertilizer water directly to water the roots. You need to pour it slowly from the edge of the pot, otherwise the roots will be damaged.
