O.K. If miracle grow will help plants not absorb the Sh, and sodium hydroxide will neutralize SH, and some garderners mix the 2 together to boost the effectiveness of the miracle grow, would it help us to spray this on some of the more " expensive " landscaping before spraying a roof ? Doing a little thinking.....

Dave,...sodium hydroxide and sodium hypochlorite are completely compatible. So there's no way it's neutralizing sodium hypochlorite. Not sure about the rest of what you're doing there,...but I wanted to at least let you know that bit of info before you go spraying hydroxide on SH thinking it will neutralize it.
Doesn't Sodium Per-carbonate kill bleach? Or is it the other way around?
I love that picture of all the snow in your avitar. The season will be over not having to work anymore, sleeping in, going hunting, preparing thanks giving dinner, christmas shopping, spending lots of time with the grandchildren, taking trips to Florida trying to win Lori over, what do you think.

I agree but I need 1 more month of good weather to finish a huge paint job I'm on now. I'm stuck roof cleaning and powerwashing in the light rain.

Yes and some things mixed together go BOOM! Didnt want to openly scold someone on a forum. That is whay I said "call me".
Why I asked this was because I cleaned a roof at a house, and he had beautiful plants around his pool. I asked how he kept the chlorine from killing his plants. He told me he sprays them once a week with a mixture of miracle gro- hydrogen peroxide- water. After some research, hydrogen peroxide is used in the clothing industry to stop the bleaching action of sodium hypochlorite on clothing, by neutralizing the hypochlorite. I know mixing the 2 will cause a reaction, but, like anything, done right it is safe.
good neutralizers for chlorine There are three good alternatives for neutralizing hypochlorite bleach: bisulfite or metabisulfite, thiosulfite, or peroxide. Bisulfite and metabisulfite Bisulfite, or metabisulfite, is the most economical choice. It is widely sold under the name Anti-Chlor by dye suppliers. It does not matter whether you buy sodium bisulfite or potassium bisulfite. It is economical because only small amounts are required. If your dye supplier sells anti-chlor, be sure to order some the next time you order dyes. Bisulfite is also used as a preservative of fresh and dried foods, such as the potato salad in restaurant salad bars, or dried apricots. A good local source would be your local home wine brewing supply store, as sodium bisulfite is widely used for sanitizing the fruit juices to be used in wine, to stop yeast growth, and as a preservative. Camden Tablets are a product sometimes used in wine-making; each tablet contains 1/16th teaspoon (0.3 ml) of sodium bisulfite. Here is the chemical equation describing the neutralization reaction between sodium hypochlorite and sodium metabisulfite: Na2S2O5 + 2NaOCl + H2O —> 2NaHSO4 + 2NaCl An alternative reaction is as follows: Na2S2O5 + 2NaOCl + H2O —> 2Na2SO4 + 2HCl (Source: R.J. Xie et al. Desalination and Water Treatment vol. 3 (2009): pp 193–203 [PDF].) Thiosulfate Sodium thiosulfate, also known as Bleach Stop, is another excellent choice for neutralizing chlorine bleach. It is less economical than Anti-chlor because you must use a much larger quantity to prepare your bleach neutralizing bath. Thiosulfate is commonly used in developing photographs, so you may be able to find a local supplier in the form of a photography supply store. The reaction between thiosulfate and hypochlorite is as follows: 4 NaClO + Na2S2O3 + 2 NaOH → 4 NaCl + 2 Na2SO4 + H2O Peroxide Hydrogen peroxide is a third choice, perhaps preferable for asthmatics who are sensitive to the effects of sulfur-containing chemicals. It is more expensive than Anti-chlor or Bleach Stop, but it has the advantage of being readily available at pharmacies. Look for 3% hydrogen peroxide among the first aid supplies at your local drug store. The chemical reaction between hypochlorite (the active ingredient in chlorine bleach) and hydrogen peroxide is as follows: OCl- + H2O2 -> Cl- + H2O + O2 How much bleach neutralizer do I need to use? Thiosulfate (Bleach Stop) is not as strong as Anti-chlor (sodium metabisulfite). You need to use one whole ounce by weight (30 grams) of Bleach-Stop (sodium thiosulfate) per gallon of warm water, or a pound and a quarter for a twenty-gallon washing machine load — so, using your washing machine for this step would be very expensive and you'd better stick to a bucket, but you can do that. Cost per gallon of bleach neutralizing bath, 25¢. Not too expensive. In contrast, you need only one teaspoon, or 2.2 grams, of Anti-chlor (sodium metabisulfite) per 2.5 gallons of water, or less than half a teaspoon per gallon of water. That works out to 18 grams per twenty-gallon washing machine load, if you like to use it there. Cost per gallon of bleach neutralizing bath, three-quarters of 1¢. Very, very inexpensive. Cheap enough even to use in the washer, if you're lazy about carrying buckets around, or if you want to use it as a regular laundry additive to reduce unwanted bleaching from chloramine in your water supply. Buy whichever one your dye supplier sells, and be careful to use no less than their instructions say to. Rinse your garments in water quickly before neutralizing. ALWAYS fill your bucket or washing machine with rinse water to do this BEFORE you start to apply bleach to your fabric. I'm not sure how much 3% hydrogen peroxide is absolutely required. I had good results by pouring half a bottle over my project; at $.79 per bottle, that was about 40¢ per use. Far less economical, but convenient for those times when you don't have any Anti-Chlor in the house and your next order isn't due to be delivered until next week. It works very well, too: although I had to leave that particular shirt in the bleach a long time to get my design, it never did develop any holes in the bleached part, over hundreds of washings. (There was no spandex or other synthetic fiber is the shirt, which helps a lot.) It eventually developed unrelated rips elsewhere on the shirt. I can certainly recommend 3% H2O2 as effective, even if not the most economical option
I have always used thiosulfite to rinse my pumps etc with. I began using it to rinse landscaping down too and it has made a difference. I got the idea from when I use it to lower Chlorine levels in my pools after super super chlorinating them after some kid sheds some soup in them.

Sodium thiosulfate crystals can be mixed with water to make chlorine remover. To do this, take 4 ounces of the sodium thiosulfate crystals and mix them into one gallon of water (the cleaner the better). Use one drop of this mixture per gallon of water you wish to dechlorinate. 1 gallon will treat 60,000 gallons. Sounds like some potent stuff. A 55# bag for $65. A bag should last a long time.
