The Best Fertilizer for a Ficus Audrey
With its broad, oval leaves, pale veins, and distinctive sculptural trunk, the Ficus Audrey (Ficus benghalensis 'Audrey') is an elegant alternative to the classic Fiddle Leaf Fig. Like most indoor ficus, it benefits from regular feeding during its active growing season—but the right fertilizer and application schedule matter.
So, what is the best fertilizer for a Ficus Audrey? And how often should you fertilize it? Here's what you need to know.
When Should You Fertilize a Ficus Audrey?
Fertilize your Ficus Audrey primarily during its active growing season, generally from spring through early fall.
A liquid fertilizer can typically be applied every two to four weeks during this period, depending on the strength of the product. Always follow the manufacturer's recommended dilution and avoid applying fertilizer to completely dry soil.
During the winter, when light levels and growth naturally decrease, reduce or stop fertilizing. Houseplants generally need little additional fertilizer during this period.

What NPK Ratio Is Best for a Ficus Audrey?
For a Ficus Audrey, look for a fertilizer with a higher proportion of nitrogen, since nitrogen supports healthy leafy growth.
A ratio around 3-1-2 or 3-1-3 is appropriate for ficus grown as indoor foliage plants. UF/IFAS recommends these ratios for commercial interiorscape ficus, while the RHS recommends a high-nitrogen fertilizer for ornamental figs.
NPK refers to nitrogen (N), phosphorus (P), and potassium (K). The numbers on a fertilizer label indicate the relative amount of each nutrient.
More fertilizer isn't necessarily better, however. Over-fertilizing can cause fertilizer salts to build up in the soil and damage the roots or leaf margins.
What Is the Best Plant Food for a Ficus Audrey?
We recommend Boost Vitaminé our gentle liquid plant food made with just four ingredients.
Its liquid formula makes it easy to dilute and incorporate into your regular watering routine. For a Ficus Audrey, use it during the growing season according to the recommended application rate.
Can Fertilizer Make a Ficus Audrey Grow Faster?
Fertilizer can support healthy new growth, but it can't compensate for insufficient light or inconsistent watering.
Ficus Audrey prefers bright light and moist but well-drained soil. It also benefits from warm temperatures and moderate to high humidity.
If your Ficus Audrey isn't growing well, check its growing conditions before adding more fertilizer. Too little light, overwatering, underwatering, or sudden environmental changes can all cause problems.
