I had my house power washed with a bleach mixture. I asked if I should cover my plants and he said no. They would water good before they started. Two days later my new ready to bloom lavender is turning gray and wilting and coneflowers have big holes in the leaves and blooms on roses are dying. I watered realllly good when I saw this. Can they be saved ??

This isn't the first report we've had of bleach power-washing runoff destroying plants. These companies should a) know better and b) be required to make reparations, especially if they assured you that no harm would occur. It's no mystery that bleach can damage or destroy plants.

My personal rant aside, the most you can do is keep them well watered and wait. You might not know until spring. If those are all established plants, chances are favorable that they'll survive, but it sounds like you will lose current blooms. I'd also recommend pruning off as much damaged foliage as you deem wise at this time of year.

So sad!
