When your elephant ear may benefit from feeding

  • When your elephant ear emerges in warm weather and begins rapidly expanding new leaves
  • When your large container-grown elephant ear is actively growing and its root area has limited available nutrients
  • When your elephant ear is producing multiple large new leaves through a warm, well-watered summer in a garden bed
  • When your overwintered elephant ear resumes healthy growth after replanting or moving outside into suitable temperatures

Yellowing or browning elephant ear leaves can reflect cold, wind, or inadequate moisture. Fertilizer cannot reverse seasonal dieback.

What's inside
The 3.6-3-5.1 ratio is built for a plant judged entirely on leaf size. Nitrogen at 3.6% fuels continuous new leaves through the growing season, and potassium at 5.1% — the highest of the three — supports the water movement and stem strength a four-foot leaf demands. All of the nitrogen is nitrate nitrogen, the form roots absorb directly, so response is fast in the consistently moist soil elephant ears prefer.

Beyond NPK: sea kelp (Ascophyllum nodosum) for natural growth compounds, plus calcium at 2.1% — unusually high, and what builds rigid petioles that hold leaves up instead of letting them flop — magnesium (0.75%), iron, manganese, zinc, boron, and copper. Magnesium and iron are the pair elephant ears run short of first, showing as yellowing between the veins on the oldest leaves.

How to care for elephant ears

Light

Part shade to full sun depending on the type: colocasia takes more sun as long as water keeps up, while alocasia prefers bright, filtered light and afternoon shade.

Water

Elephant ears want constantly moist soil, and colocasia is happy at a pond edge. Water deeply in heat and do not let the soil dry out between waterings.

Soil

Rich, moisture holding soil with plenty of compost, pH about 5.5 to 7.0. Plant tubers roughly four inches deep with the blunt, rooted end facing down.

Temperature

They grow fastest above 70F and sulk below 60F. Colder than zone 8, lift the tubers after the first frost and store them dry and frost free.

Feeding

These are heavy feeders. Use Elephant Ear Fertilizer with your watering every one to two weeks through spring and summer, then stop while your elephant ear rests in winter.

Pruning

Cut yellowing or torn leaves off at the base so energy goes into new ones. In season a healthy plant pushes out a fresh leaf every week or two.

Frequently asked questions

How often should I feed my elephant ears?

Elephant Ear Fertilizer is built for frequent feeding, because elephant ears are heavy feeders and heavy drinkers, and the constant watering they want flushes nutrients out of the soil quickly. Mix 2 tablespoons per gallon of water and feed every 1–2 weeks in spring and summer while your elephant ear is pushing leaves, then every 4 weeks in fall and winter for plants kept growing. Mixing it into your regular watering keeps nutrition steady. A hose-end sprayer on the 1-ounce setting covers in-ground beds and pond margins.

How do I get bigger leaves?

Leaf size comes down to steady nutrition, consistent moisture and enough light, and Elephant Ear Fertilizer covers the first. Nitrogen at 3.6% fuels continuous new leaves, potassium at 5.1% supports the water movement and stem strength a large leaf demands, and calcium at 2.1% builds rigid petioles that hold the leaf up rather than letting it flop. Feed every 1–2 weeks through the growing season, keep the soil from ever drying fully, and give bright light; each new leaf tends to outsize the one before it.

My older leaves are yellowing between the veins — is that normal?

Some yellowing on the oldest leaves is natural as your elephant ear redirects energy to new growth. A vein-by-vein pattern, where the veins stay green and the tissue between them yellows, usually points to a magnesium or iron shortfall, and those are the two elephant ears run short of first. Elephant Ear Fertilizer carries magnesium at 0.75% and iron alongside manganese and zinc. Leaves already yellowed won’t turn green again, but new growth should come in dark and even within a few weeks of regular feeding.

Should I keep feeding through winter?

It depends on whether your elephant ear is growing. For elephant ears kept growing indoors or in warm zones, feed Elephant Ear Fertilizer every 4 weeks through fall and winter, at 2 tablespoons per gallon. Plants that go dormant, dropping their leaves or lifted as tubers for storage, aren’t taking up nutrients and shouldn’t be fed until growth restarts. When the first new leaf appears in spring, return to the every 1–2 week schedule and your plant picks up where it left off.

Will this burn my plant?

Elephant Ear Fertilizer is a dilute liquid feed, and dilution is what matters here. Fertilizer burn happens when concentrated salts sit against the roots: too much product in too little water, or granules piled at the base of a plant. Mixed at 2 tablespoons per gallon and applied every 1–2 weeks, the nutrients arrive in solution at a strength the roots take up as they water, and all of the nitrogen is nitrate, which roots absorb directly. For freshly planted tubers or recently divided plants, start at half strength for the first two feedings.

When will I see results?

Elephant ears respond fast in warm weather. With regular feeding of Elephant Ear Fertilizer, new leaves typically come in greener and larger within the first few weeks, since the nitrate nitrogen and micronutrients are available as soon as they’re watered in. Each subsequent leaf should size up further through the season as your elephant ear builds on steady nutrition. Plants that have been in the same pot for more than a year, where the mix has run low on nutrients, usually show the clearest change.
