Diamond Crown Hardy Water Lily (ISG) – Proper Planting and Care

1. Diamond Crown Hardy Water Lily Depth: Plant 8–16 inches from the water surface (shallower = more blooms).

2. Diamond Crown Hardy Water Lily Container: Use a very wide pot—16 inches minimum (wider = better).

3. Soil: Only heavy loam soil (no bagged mixes, compost, or gravel).

4. Sun: Full sun (at least 6–7 hours of direct light) for consistent flowering.

5. Space: Give the Diamond Crown Hardy Water Lily open water around the pads—avoid crowding from other water lilies or floating plants.

Note: ISG hardy water lilies prefer shallow, warm placements early in the season to wake up and bloom well.

Diamond Crown Hardy Water Lily Fertilizing Schedule

• Feed heavily and regularly.

• Use Waterlily World Fertilizer Tablets on the 1st and 15th of each month during the growing season.

• Start with 4–6 tablets pressed 3–4 inches into the soil around (not on top of) the rhizome.

• ISGs are hungry plants—consistent feeding keeps flowers coming.

Do’s and Don’ts for Diamond Crown Hardy Water Lily

Do’s
✅ Plant the Diamond Crown Hardy Water Lily 8–16 inches deep in full sun.
✅ Use a 16"+ wide fabric or rigid container with heavy loam soil.
✅ Fertilize twice monthly for continuous blooms.
✅ Divide annually (ISGs especially benefit from yearly division to avoid dormancy).
✅ Provide open space so pads and flowers get light and airflow.

Don’ts
❌ Do not cover the crown with stones, gravel, or aquatic media—this suffocates the plant and reduces flowering.
❌ Do not use bagged soils with compost or peat—these float and decay in water.
❌ Do not let floating plants or nearby lilies shade or crowd this hardy water lily—light competition reduces blooms.
❌ Do not let the Diamond Crown Hardy Water Lily dry out during unpacking—keep roots, stems, and leaves wet and plant immediately (no acclimation needed).
❌ Do not skip division—ISGs can stall if not given a fresh cut and room to grow each year.
