Elephant Ear Fertilizer

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.

At 1 tsp per quart, the 8 oz bottle makes about 48 watering cans of feed. For a typical shelf of 10–15 plants fed every 1–2 weeks in season, that's several months of feeding — and the 32 oz bottle four times that.

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.

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.

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.

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.

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.
