DO NOT start dumping things on the plants - nop fertilizer, no vitamins, etc. Just trim off the dead stuff and continue to water as needed.

They MAY die from the chloring ... they WILL die if you stress them further by applying more chemicals.

I would add, drench them with water to further dilute the chemical.

Then send the pool maintenance company a certified letter confirming that they admitted fault during your conversation.

If you lose your plantings, send the pool maintenance company a bill & if they don't pay it, report it to the licensing entity in your state/county/whatever, report to Better Business Bureau (won't do any good, but maybe the pool company doesn't know that!), &, as a last resort file suit in small claims court.

If I owned that company, I would not want my name on public record as having been sued by a consumer for destroying her landscaping.

What if your pets had been out there?

Heck, what if your kid had traipsed out there???

Well they took there sweet time getting out to my house to look at the damage....a week to be exact! Every time I looked out there I got mad, just wanted to cut it all back but had to leave some of the damage so they could see it. I let them know that chlorine gas is no longer permitted on the property! And they agreed to pay for the cost of replacing everything. The manager told me to give him a call and let him know how much it will cost. I explained to him that I grew all these flowers and the gourd vine, and spanish flag by seed and that they are annuals. Also, that with the weather heating up now I will not replant annuals as they will most likely not survive. Anyhow, we'll see if they give me hard time when I call them to give them a number ($)
He told me that they also had another employee just kill someones prize geraniums by dumping salt into the flower bed, then he said "I'm learning alot of gardening tips by putting out the fires" Geez! Salt?!
Thanks for your advice,
