Judi,

I toss all my pond algee in the compost wet. In addition at the end of the year I also toss in all the dying aquatic plants such as Water Hyacinth and Parrots Feather.

Composting algae is the same as drying medusa on my opinion.

Thanks Mike for the answer. Now I'm sorry about all I have wasted. Half acre pond that really gets covered. Now I won't feel so bad about all the work it is to get it out.
Thanks again, Judi

There is an article on the web someplace where a Minnesota heirloom tomato grower used pond weed for mulch. If I recall it didn't aid growth any better than anything else he used, but it didn't have any adverse affects.

Carbon to nitrogen to phosphorus ratio is approximately 105:16:1

sounds like a sure material to add to your pile

on the other hand have you tried a bale of barley straw in the pond to keep the algae from growing

Hi Jonas, never heard of barley straw. Is it safe for the fish, frogs, turtles etc? If so, it sure would beat pulling all that heavy algae out. I was only thinking about my flowers and starting a compost pile.

Lake Monona has an algae problem every summer. Please tell us more about barley straw.

Algae blooms on lakes and ponds has increased as the pollution from Nitrogen and Phosphorus has increased. Some of the Algae would be a good addition to any compost pile as long as you know it is not the Toxic Blue/Green Algae that is also becoming more of a problem.

This was a decent article on the pros and cons of barley for algae control

Judi says her pond is half an acre. That's an awful lot of barley straw.

There is different algaes.one fed one way one another.like cow pasture compared to millions of years ago inlandsea phytoplankton deposit. Two extremes. Or better pig industrial area.oil product area.
