Pothos (*Epipremnum aureum*) is a hardy, low-maintenance plant, but it still requires proper nutrition to thrive. As a tropical plant, it benefits from a balanced supply of nitrogen (N), phosphorus (P), and potassium (K), along with trace minerals like magnesium and calcium. Nitrogen supports leafy growth, phosphorus strengthens roots, and potassium enhances overall plant health. Since pothos grows in a variety of conditions—from soil to water—its fertilizer requirements may vary slightly depending on its environment.
The ideal fertilizer for pothos is a balanced, water-soluble formula, such as a 10-10-10 or 20-20-20 NPK ratio. Liquid fertilizers are preferred because they are easily absorbed and allow for precise control over nutrient delivery. Organic options like fish emulsion or worm castings can also be used, providing slow-release nutrients while improving soil health. Avoid high-nitrogen fertilizers, as they may promote excessive foliage growth at the expense of root development.
Pothos should be fertilized during its active growing season, typically from spring to early fall. During this period, the plant is producing new leaves and stems, requiring more nutrients. Reduce or stop fertilization in winter when growth slows. Over-fertilizing during dormancy can lead to salt buildup in the soil, causing root burn. For hydroponic pothos, a diluted fertilizer solution should be refreshed every 4-6 weeks to maintain nutrient levels.
To avoid over-fertilization, dilute liquid fertilizer to half or quarter strength and apply it every 4-6 weeks during the growing season. For soil-grown pothos, water the plant thoroughly before fertilizing to prevent root damage. Apply the fertilizer directly to the soil, avoiding the leaves to prevent burns. For hydroponic setups, mix the fertilizer into the water according to package instructions and monitor for signs of nutrient deficiency or excess.
Yellowing leaves with brown tips may indicate over-fertilization, while pale or stunted growth suggests a nutrient deficiency. If over-fertilization occurs, flush the soil with distilled water to remove excess salts. For deficiencies, adjust the fertilizer type or frequency. Always observe your pothos closely after feeding to ensure it responds well to the nutrients provided.
Pothos grown in low-light conditions require less fertilizer than those in bright, indirect light, as their growth rate is slower. For plants in water (hydroponics), use a hydroponic-specific fertilizer to ensure all essential nutrients are available. Soil-grown pothos benefit from occasional top-dressing with compost or slow-release granules to maintain soil fertility.
