too much barley straw in pond
OK - here's what happened. I dug a pond in my front garden.. an area that gets 14 hours of bright sunshine every day. I do not have fish or anything else in it.
Almost immediately, it filled with blanket weed.
Meanwhile, in the back veggie garden, we had installed several bales of barley straw, thoroughly rotted down, to raise the gardening surface and help out my wife's bad back. They appear to be working just fine.
And then I read that barley straw is a great way to get rid of blanket weed.. and I figured that, if I put several bales in the pond, they would defeat the weed and allow me to plant bog-plants in the bales... win/win.
I did this - and, within a week, the pond water turned dark brown and smelly and developed a horrible-looking scum on the surface...
Turns out, this was the floating bits of straw rotting in the water...
I drained the pond and gave the bales a few days to dry sufficient to be able to haul their dead-weight out of the pond.
All but one were placed in the sun and the missus planted some tomato plant seedlings in them.
The remaining one went into the OTHER PROJECT.
We had been given a LARGE stock-watering pond.. about 8 feet across and 4 feet high.. heavy -duty black plastic. It was too tall for ducks and too big for me to dig a hole big enough to sink it in... so we decided to make a flower-bed/arrangement kinda thing, with a nice fountain in the middle and we took the one remaining straw bale and stuck it under the fountain in the duck pond.
and, of course, it has now begun to turn the water brown.. and develope a froth..
And we can LIVE with that...
The question is... can the water be used on our plants and will the straw residue be of benefit to them, if we use it?
Thanks to anyone with any advice...
