When your lotus may benefit from feeding

  • During warm-season growth, when lotus push large pads and blooms and feed heavily
  • For established lotus and water lilies producing few or small blooms
  • When newer pads yellow, which often points to iron used up in fast summer growth
  • For bowl lotus and dwarf varieties in patio containers, dosed at 1 tsp per 10 gallons scaled to the container's water volume
  • Once new growth appears in spring and the water warms, after the winter rest

Bloom also depends on full sun and warm water, so feeding makes sure nutrition is not the limit rather than replacing either.

How to care for lotus and water lilies

Light

Full sun, at least six hours a day. Lotus and water lilies flower poorly in shade, so give them the brightest part of the pond or patio.

Water

Keep the tuber or crown submerged all season, with roughly four to twelve inches of water over the soil. Top up ponds and bowls as they evaporate in heat.

Soil

Heavy garden loam or an aquatic planting mix in a wide container with no drainage holes. Cap the surface with gravel so the soil does not cloud the water.

Temperature

Growth starts once water reaches about 70F and carries on through summer. Hardy types overwinter if the tuber stays below the ice line, while tropicals must come indoors.

Feeding

Feed Lotus Fertilizer through the active growing season, from the first standing leaves until flowering ends in late summer, then stop as your lotus goes dormant.

Pruning

Trim yellowing leaves and spent flowers above the water line, never below it, because cut stems under water can flood and rot the tuber.

Frequently asked questions

How often should I feed my lotus?

Once a week in high light or summer, once a month in low light or winter. For a lotus in a container water garden, add 1 teaspoon of Lotus Fertilizer per 10 gallons of water and stir gently to circulate it. For a pond, use the same 1 teaspoon per 10 gallons in a high-flow area. Lotus are heavy feeders during warm-season growth, so steady weekly feeding through summer supports their large pads and blooms, and they need little to nothing while dormant.

Why won't my lotus bloom?

The most common reason is not enough sun. Lotus need full sun, ideally six or more hours, and won’t flower well in shade however you feed them. Warmth matters too: they bloom in the hottest part of summer and stay quiet until the water warms. Young or newly divided plants often spend their first year establishing before flowering. Lotus Fertilizer is potassium-led, and potassium supports flowering, but sun and warmth are what drive it; the formula makes sure nutrition isn’t the limit.

Why are my lotus leaves turning yellow?

Some yellowing of older pads is normal as they age and are replaced. Widespread yellowing on newer growth more often points to iron, which lotus use up quickly in strong summer growth, and Lotus Fertilizer carries iron in its micronutrient package for exactly that reason. In very alkaline water, plants struggle to take up iron even when it’s present. Feed on schedule and check sun and warmth, since a lotus growing slowly in cool or shady conditions also looks pale.

Do I fertilize my lotus in winter?

Barely. Lotus go dormant when the water cools, dropping their leaves and resting in the tuber, and they need very little then. Cut back to once monthly at most in low light and cold, or stop entirely if your lotus is fully dormant. Feeding a dormant lotus loads the water with nutrients your plant isn’t using, which feeds algae instead; Lotus Fertilizer keeps nitrogen low for that reason, but even so, less is right in winter. Resume weekly feeding in spring once new growth appears and the water warms.

When will I see results?

Stronger pads and better bloom show on new growth first in warm, high-light conditions, when lotus grow fast. The iron in Lotus Fertilizer supports deep green pads and rich flower color, and the potassium supports flowering as the season progresses. Results are minimal in cool or dormant periods when your lotus isn’t growing. Pads that have already yellowed won’t re-green; you’re feeding the new growth and the blooms that follow through summer.
