What fertilizer should be used to make orchids grow well? What fertilizer should be used to make orchids grow fast and well?

Domestic orchids are confined to flower pots, and the fertility content in the planting material is relatively limited. If no fertilizer is applied, the growth of orchids will inevitably be affected. How to fertilize orchids is a topic that orchid lovers have been exploring. So, what is the best fertilizer for orchids?

Organic Fertilizer

Usually, the organic fertilizer (special for orchids) I refer to is cake fertilizer. After all, although other organic fertilizers in rural areas have good fertility, they are obviously not suitable for growing orchids. At least the smell is unbearable.

The cake fertilizer applied to orchids has a very obvious effect on the growth of orchid seedlings . It makes the orchid leaves dark green and thick, upright and elegant. It also has a good effect on promoting the bud formation and flowering of orchids .

fertilizer

Fertilizers from general agricultural supply stores can be used when planting orchids (except those containing chlorine). We can use fertilizers with different nitrogen, phosphorus and potassium contents according to the different growth stages of orchids.

The most commonly used fertilizer by many orchid lovers is triple fertilizer , which generally contains 17% nitrogen, phosphorus and potassium each, and the potassium element exists in the form of potassium sulfate.

The effect of chemical fertilizers applied to orchid pots is very fast. Generally, the fertility can be clearly felt within 7 days. The leaves begin to turn green and the growth rate of new seedlings is significantly accelerated.

However, we should also be careful when applying chemical fertilizers to orchids. Chemical fertilizers can easily cause premature aging of orchids , especially some older orchid seedlings. And we must be particularly careful when using them, otherwise there will be a risk of fertilizer damage .

Biological fertilizer

Biofertilizer is a fertilizer that has been used more by orchid lovers in recent years. It does not contain nitrogen, phosphorus, and potassium, which are essential elements for plant growth. The main function of biofertilizer is to mobilize the effective ingredients in the soil, activate them, and make them easier for plants to absorb and utilize.

Biofertilizer is easy to use and can be mixed into the planting material when planting orchids without the drawbacks of fertilizer damage. This fertilizer does not take effect quickly, and the planting material itself has its own fertility, so it can be actively mobilized. If you use pure inorganic planting materials, the use of biofertilizer will basically have no effect.
