What kind of fertilizer is good for orchids (base fertilizer application method)

The role of orchid fertilizer

Applying base fertilizer to orchids is a very important task. Usually, orchid seedlings with base fertilizer will grow stronger, have lush leaves and increase the disease resistance of orchids. It is generally recommended to apply base fertilizer in autumn, that is, at the time of planting.

Orchid fertilizer selection

When planting or repotting orchids, you can choose to use some solid fertilizer as the base fertilizer, such as fully decomposed cake fertilizer, which contains more organic matter, which is conducive to future growth.

When repotting orchids, you can apply some base fertilizer, but it is not necessary. The planting materials of orchids generally contain a large amount of humus, which themselves have a certain fertility, and orchids do not like fertilizer.

How to apply base fertilizer for orchids

If the base fertilizer for orchids is solid fertilizer, then when planting or repotting, just mix it evenly with the soil, and then plant the plants in the potting soil.

How much base fertilizer should be used for orchids?

When potting, mix the formula fertilizer and cake fertilizer in the planting material, generally in a weight ratio of 1:20. That is, if there are 20 kilograms of prepared planting material, add 1 kilogram of fermented cake fertilizer. After thoroughly mixing, you can plant orchids.

How to fertilize orchids

In the spring and autumn seasons when orchids grow more vigorously, you can apply organic nutrient solution every other week. Dilute it 500 times and pour it around the root system. After changing the potting soil, you can wait about 3 weeks before applying fertilizer once.

During the flowering stage, phosphorus and potassium are mainly used to promote the growth of orchids. In addition, orchids can be fertilized with foliar fertilizer once every half a month.
