Why do all my pond plants turn yellow?

I don't have plants this year because every previous year I've tried and they turn yellow. I have some koi and some various other goldfish and they are healthy and large. I'm wondering if they were eating the roots and subsequently killing the plants from underneath. I never saw them doing this, and I feed my fish pretty well, so they shouldn't be hungry. I'd like to have plants again but I don't see the point. Also, when I had plants last year, I had a huge amount of that hairy algae that I'd never had a problem with before. Plants are supposed to be beneficial but something's wrong with the balance of my pond, apparently. It's in almost full sun and it's hot and humid in the summers here in Illinois. Any ideas why I have trouble?

hard warer should not cause this problem, your plants may not be getting the nutrients they need, try putting pond plant fertilizer tabs in the lilly pots, mine a blooming beautifully. to get rid of the hairy algea, add some barley straw bales or powder. it takes a while, but kills all types of algea, no harm to pond plants or fish.

Reply:maybe they don't like you
Reply:Do you have a county agricultural extension agency there ? They could advise you on testing the water. There may be nurseries who sell water testing kits. Sounds as if your plants are not getting the right sort of nutrients. Testing for the ph of the water - and other variables, would be advisable.
Reply:check the ph of the water. it should be between 7.0 %26amp; 8.0


also, check to see if the fish really are eating the roots.


if the pond is in full sun, try to give it some cover.


nutrient levels can be fixed with a little soil at the bottom of the pond.


see if your local garden supply has anything to check the O2 (oxygen gas) levels


these are just a few reasons - your local garden shop may be able to give you a few more to investigate
Reply:too much watering maybe
Reply:Plants often turn yellow from too much water. You may be putting plants in that don't do well in your climate or elevation. Get some help from a local nursery, they can point you in the right direction so that your plants will flourish instead of fade.
Reply:Your plants aren't getting enough oxygen to photosynthesize, which produces chlorine that turns the leaves green, so without it they turn yellow or brown. Try putting a bubbler in your pond to add more oxygen, it really helps.
