I have sprayed my Hydrilla, now I am waiting for it to die. I've read that I am supposed to remove it from pond but my physical condition won't allow me to rake my 1 acre pond. Does the Much Away work for dead hydrilla? Or is there a better way to help it decompose faster? I do have TWO areators / diffusers on the pond to pump air and turn the water over running 24/7. Thanks in advance for your help!

Does spraying kill hydrilla in cold weather? I thought it went dormant, like many plants, until spring.

I am not sure if it will kill it, I've been gone for the past 6 months for work and came home to an overgrowth of hydrilla and had to try to kill it. It is still very green. I made a make shift sub-surface spray mechanism to get the poison down to the roots, added a little pond dye to see where I was spraying and I am hoping I can kill a lot of it before we get cold down here in Louisiana. I will hopefully be able to catch it in the spring when it starts to grow and knock it down. I'm getting a permit to buy some grass carp so I can hopefully keep it under control without chemicals again.

You must live in southern Louisiana if it hasn't gotten cold yet! We've had several freezes already up near Shreveport.

Good luck with the grass carp. I've gotten permission to stock them, though my problem is bushy pondweed not hydrilla. Had it killed chemically in the summer, but I don't want to keep doing that.
