Nitrogen is a particularly crucial component since it aids in the production of chlorophyll and the development of healthy orchid leaves. Orchids need huge amounts of nitrogen for their growth, much more than other ordinary flowers.


Phosphorus plays a crucial role in forming strong root development, seeds, and blooms. Similar to nitrogen, orchid plants require a huge amount of phosphorus for its development. Therefore, its food often contains a high density of this component, which can be a serious problem when feeding it to other plants.

Most healthy plants need about 5% phosphorus, while these lovely orchid ones demand 10%.

Once again, you must be extremely careful with the amounts of fertilizer used for other flowers. Or else, you will possibly overdose on them!


Last but not least, potassium is also a vital element in keeping a healthy status for orchids. Luckily, the required ratio is quite close to that of other flowers. Consequently, you won’t have to pay too much attention to the amount.
