Water Lotus Planting: Soil, Containers, and Seed Viability

Planting Germinated Lotus Seedlings Successfully

A grower with one sprouted lotus seed (from 10) asked about using yard soil (with walnut trees), container size (1.5-cup food containers), and whether floating seeds that later sank were viable.

Key Planting Guidelines

• NO walnut/hickory soil: Contains juglone—toxic to many plants
• Use proper aquatic soil: Clay-based or commercial aquatic mix
• Container: Wider than deep; 1.5 cups too small for long-term
• Gravel top-dressing: 1+ inch prevents soil float-out
• Submersion depth: Roots must not freeze in winter

Seed Viability Notes

• Floating seeds often infertile; sinking after soaking may indicate viability
• Germination method: File seed coat, daily water changes, warm water
• Delicate seedlings need protected, shallow start

Don't use yard dirt. Buy aquatic potting soil. Start in wider containers.
