Water Lily Planting Tips
-
Plant shallow (6–10") to warm the crown and ramp up buds
-
Choose wide, shallow containers—more rhizome run = more flowers
-
Keep surface water open and unshaded; pads are your “solar panels”
-
Avoid splashing/aeration directly onto pads; still water shows blooms best
-
Start with a normal feeding, then increase to ISG rates as growth surges
Do’s & Don’ts
Do
-
Plant in full sun and heavy loam for best performance
-
Fertilize twice monthly at ISG rates (1.5–2× standard hardy)
-
Repot immediately on arrival; keep all parts wet while planting
Don’t
-
❌ Don’t use compost/peat mixes, “aquatic media,” or gravel (they float, rot, or smother crowns)
-
❌ Don’t let floating plants shade Luxor—light drives flowering
-
❌ Don’t plant too deep (>10–12") if you want frequent blooms
-
❌ Don’t place in cold spring water—ISGs stall below ~70°F at the crown
