Elephant Ear Fertilizer
Elephant ear fertilizer with a nitrogen-forward 3.6-3-5.1 NPK, kelp, and eight added minerals — made to push the oversized leaves these plants are grown for. All-nitrate nitrogen drives leaf after leaf, while high calcium and potassium build stems strong enough to hold them upright instead of drooping under their own weight.
How to Use Elephant Ear Fertilizer
| Method | Amount | How Often |
|---|---|---|
| Watering can | 2 Tbs (30 mL) per gallon of water | Spring & summer: every 1–2 weeks |
| Watering can | Same dilution | Fall & winter: every 4 weeks |
| Hose end sprayer | Set dial to 1 oz (30 mL) setting | Spring & summer: every 1–2 weeks |
| Leaf misting (optional) | 1 tsp per quart (32 oz) of water | Every 1–2 weeks |
Mix into your normal watering — no separate feeding routine needed.
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.
Made For
Elephant ears of every type: Colocasia, Alocasia, and Xanthosoma — in-ground beds and pond margins, patio containers, indoor specimens, and tubers lifted and overwintered in cold zones.
Problems It Solves
- Small new leaves that never reach full size
- Yellowing between the veins on older leaves
- Drooping leaves and weak, floppy stems
- Slow growth or few new leaves through the season
FAQs
How often should I feed my elephant ears?
Every 1–2 weeks during spring and summer while the plant is actively pushing leaves, and every 4 weeks in fall and winter. Diluting into your regular watering (2 Tbs per gallon) matters here — elephant ears are heavy feeders and heavy drinkers, and frequent watering flushes nutrients out fast.
How do I get bigger leaves?
Leaf size comes down to three things: steady nitrogen, consistent moisture, and enough light. This formula covers the first, running nitrogen at 3.6% with potassium above it for the stem strength big leaves need. Pair regular feeding with soil that never fully dries and bright light, and each new leaf should outsize the last.
My older leaves are yellowing between the veins — is that normal?
Some yellowing on the oldest leaves is natural as the plant redirects energy, but a vein-by-vein pattern usually means magnesium or iron shortfall. Both are in the formula. Existing yellowed leaves won't turn green again, but new growth should come in dark and even within a few weeks.
Should I keep feeding through winter?
Feed every 4 weeks through fall and winter for plants kept growing indoors or in warm zones. Plants that go dormant — dropping leaves or lifted as tubers for storage — should not be fed until growth restarts in spring. Resume the spring and summer schedule when the first new leaf appears.
Will this burn my plant?
No — at the directed dilution, the formula is designed for regular use. All-nitrate nitrogen and low salt concentration make burn very unlikely, even on newly emerged leaves. For freshly planted tubers or recently divided plants, start at half strength for the first two feedings.
When will I see results?
New leaves typically come in greener and larger within the first few weeks of regular feeding, and each subsequent leaf should size up further through the season. Plants that have been in the same pot for more than a year improve most noticeably.
