What is eating my victoria cruziana?
Santa Cruz water lily, slightly hardier than V. amazonica, faces the same cultivated-pond pest suite: aphids on petioles and emerging pads, aquatic snails rasping pad undersides, and occasional leaf miner fly damage inside pad tissue. Its strong spiny ribs on the underside limit surface-feeding insects. Good nutrition and warm water support rapid pad replacement.
