What fertilizer to use for growing Monstera deliciosa has always been a headache for many people. In fact, the nutrients it needs most are phosphorus and potassium. Phosphorus not only helps it grow thicker and sturdier, but also keeps it healthier, while potassium is even more impressive: it not only boosts its resistance and strengthens its root system so it can absorb nutrients better, but also prevents it from lodging.

1. Fertilizers suitable for it

Phosphorus and potassium fertilizers. These two fertilizers are very suitable for Monstera deliciosa. Phosphorus fertilizer is also called fruit fertilizer, as it helps plants grow thicker and healthier; potassium fertilizer is also called root fertilizer, and just as its name suggests, it helps the plant's roots grow stronger, prevents lodging, and at the same time increases the plant's defenses, reduces the invasion of pests and diseases, and boosts its cold resistance. Only when the roots are healthy and strong can they better absorb nutrients and water to supply the upper part of the plant.

Many fellow growers say that nitrogen fertilizer is also very suitable. That's true: nitrogen fertilizer is very suitable for foliage plants, as it can make the leaf color richer and the plant more lush. However, if used improperly, it can easily cause the plant to grow leggy, and in severe cases even make it vulnerable to pests and diseases. For Monstera deliciosa, nitrogen fertilizer is not suitable.

2. Timing of fertilization

Phosphorus fertilizer is applied in the late growth stage of the plant, and can also be buried directly in the potting soil when repotting and changing the soil each spring; potassium fertilizer is applied starting from when small sprouts emerge after sowing, during the growth period of new branches and buds, and after the seedlings are planted out; phosphorus and potassium fertilizers are likewise indispensable in the later care of the plant.
