water lilies

Question

Newer and older leaves have yellow and then black spots. These are plants that I have had before in a different pond,some in containers some out,so far I have had three flowers. I don’t recall leaves dying like this, this early.I also have Water iris that seem to be fine. We now have a waterfall and fish. The water ph has tested in the very good range for ponds.
Should I pot all my lilies and feed them? Is there something that won’t harm the fish?
Thank you.

Answer 1

The best treatment for leaf spot on Water Lilies is to remove them from the plant and discard.
If you have fish, you should not use fungicides. If the problem persists, you may want to remove and replace the Water Lily.
