Question about water celery
I have a water celery plant that I have planted in a floating container. It was doing great and was beautiful for about 2 months. All of a sudden the leaves have all turned brown and it looks like its dying. Many of it's leaves are also stripped, but I found the caterpillar responsible for that. Any ideas why all of the remaining leaves have dried up? Nothing has changed with it's location. If it matters, it's in a 300 gallon pond and I have 7 goldfish in it, no Koi. Thanks!
