Its roots are very sturdy, extremely vigorous and tenacious, and it has a good ability to purify the air, making it very convenient to keep at home. One gardening enthusiast kept this plant at home, but when it came time to fertilize it, he was at a loss, always worrying about making a mess at home and not knowing where to start. So what kind of fertilizer should it actually be given?

I. Fertilizing During the Growing Season

Fertilizing is mostly done during its growing season, which runs from May to September. In other words, fertilizing it when temperatures are above 18°C is most suitable. During this time, more fertilizer should be applied, but it is best to follow the principle of small amounts given frequently.

Give it plenty of nitrogen fertilizer, which can help the emerald green leaves grow faster. If it is liquid fertilizer, apply it once every ten days; if it is solid fertilizer, apply it once a month to a month and a half. Normally, pay attention to its growth. If its leaves turn yellow due to a lack of fertilizer, supplement with nitrogen fertilizer. After autumn, control the amount to help it get through winter. Once the temperature drops below 18°C, you should reduce or stop fertilizing.

II. Fertilizing in Winter

In winter, generally no fertilizer is needed; even if you do apply some, the amount should be small and the frequency low. If it is not too cold and it is still growing, you can fertilize it according to its condition. Do not apply heavy fertilizer. You can buy a specialized fertilizer, which is more suited to its needs and can more quickly and evenly provide the nutrients it needs for growth and development, helping it resist disease, increase its respiration rate, grow faster, and improve its ornamental effect.

III. Precautions

It is recommended to use fertilizers with good water solubility for it. You can fertilize while watering, which works very well. Do not apply only nitrogen fertilizer, otherwise the leaf stalks will grow very long and thin, making them hard to hold upright and unattractive. Using slow-release fertilizer also works very well and is very convenient; just bury it around the edge of the pot, or add it in when repotting. It is very labor-saving, and the fertilizer strength is very balanced with a long-lasting effect.
