Fertilizer can be divided into base fertilizer and topdressing fertilizer.

Base fertilizer is used for the most basic nutrition of orchids, potted flowers and foliage plants during the growth period to prevent the growth of orchids, potted flowers and foliage plants. The best base fertilizer for orchids is planting (it is a kind of granular long-acting fertilizer).

In order to meet the nutritional needs of plant growth at different stages, topdressing is given with different nutritional formulations in different periods. Topdressing can be divided into two types: liquid (liquid fertilizer) and solid (plant fertilizer), such as "plant". These topdressing are usually quick-acting fertilizers.

"Zhishuo" is divided into four formulations, which are safe to use and can replenish plant nutrition at the right time.

When planting orchids, the yellowing of leaves is light green, especially the old leaves are the most obvious, showing that the leaves become smaller and the number of buds decreases, plants show dwarfing phenomenon, poor growth and early maturity. At this time, it is best to use "Zhi Quan" with "Zhi Shuo".
