Fertilizing can make plants grow more robustly, with more brilliant colors, and flowers that bloom more beautifully. The Dutchman's pipe cactus (Epiphyllum oxypetalum) is a plant in the cactus family; its blooming time is relatively short, but the flower is very beautiful, generally opening at night. Today, the editor will share with everyone what fertilizer to use for the Dutchman's pipe cactus.

Fertilizer selection:

Cake fertilizer: Many friends say cake fertilizer is not strong enough, but based on the editor's growing experience, this is actually just right. Therefore, plants should not use heavy fertilizer. Moreover, cake fertilizer contains a relatively high amount of nitrogen, so it is very suitable for this plant.

Nitrogen fertilizer: Nitrogen fertilizer is beneficial to the growth of this plant's leaves and enhances their photosynthesis.

Potassium fertilizer: Potassium fertilizer can be mixed with nitrogen fertilizer and can make this plant's branches, stems, and leaves more thick and robust.

Iron fertilizer: Also called ferrous sulfate, this kind of fertilizer is also suitable for this plant.

Compound fertilizer: This kind of fertilizer is very easy to buy, and after fertilizing there is no other odor produced, but its fertilizer effect is not as good as other fertilizers. Its only advantage is that no odor is produced.
