Scorched Water Lily Leaves: Koi Damage or Disease?

Koi Are the Likely Culprit

Koi shred lily pads, leaving blackened edges and food debris trapped in the tears. The koi food itself doesn't harm plants.

Disease Possibility

If koi are absent, black spots + dissolving tissue = fungal/bacterial leaf spot. Remove affected leaves, improve circulation.

Solutions

• Plant lilies in cages (wire mesh cylinders) or on shelves koi can't reach.
• Feed koi away from lilies.
• Choose tough-leaved varieties (e.g., 'Attraction', 'Gonnere').
