Rhizome Establishment
7-10 daysDormant rhizome planted in soil within container; no visible growth above water yet
Keep soil consistently moist; maintain water temperature above 60°F; place in warm location to encourage sprouting
Shoot Emergence
1-2 weeksFirst leaves begin emerging from soil, appearing as tightly rolled shoots breaking the water surface
Ensure adequate light exposure; maintain stable water level; avoid disturbing the rhizome
Vegetative Growth
2-3 weeksLeaves unfurl and float on water surface; multiple leaves develop; plant creates dense floating foliage pads
Remove any dead or decaying leaves; thin foliage if it becomes too dense to maintain water circulation; feed with aquatic fertilizer tablets
Flowering
6-10 weeks (continuous during warm season)Flower buds emerge from leaf axils and float on water surface; blooms open in morning and close by afternoon; flowers are typically 1-1.5 inches wide, vibrant red color
Maintain 6-8 hours of sunlight daily; deadhead spent flowers by pinching stem below water line; fertilize every 2-3 weeks with aquatic plant fertilizer
Senescence & Dormancy
Variable; seasonal or year-round depending on climateGrowth slows as water temperature drops below 60°F; leaves yellow and deteriorate; plant enters dormancy
In cold climates, move container indoors to a cool, dark location; in warm climates, plant can continue blooming year-round; remove dead foliage to prevent water quality issues

Harvest Tips
Water lilies are ornamental flowers; deadhead spent blooms by grasping the stem underwater and breaking it cleanly to encourage continuous flowering. Remove yellowed or decaying leaves regularly. Cut flowers last 3-4 days in a vase when harvested in early morning. Propagate by dividing rhizomes in spring when new growth appears.
