Since Green Guardian is an organic product, how long can it be stored before it breaks down and is no longer effective?
In it concentrated form it will stay good indefinitely. Once diluted with water into a ready to spray formula you will need to spray it out within 24 - 48 hours. If the product begins to smell of ammonia it has gone bad and can then be used as a total vegetation control. (recycle!)
does it kick faster in the heat? if u stoped spraying at 2 pm due to heat and the truck sits in the sun could u have a mess? is there a certain ph that it should not go over?
If the soil is moist and the plants are actively growing the selective weed control products will work very well in the heat. When it is cool and/or light rain they also work, but slower. If the soil is dry and the plants are under stress then use the 5-0-3 as your best alternative. Under these stress conditions you may have to spray closer to the 6 quarts/1,000 of mixed material to get the desired outcome. I never recommend letting the truck sit in the sun as the hotter it gets inside the faster the microorganisms will populate. Keep in mind that the weed and feed liquids we have contain a good deal of organic material. Combine that with heat and being diluted (in the concentrate heat is of little concern) which activates the micro organisms to begin to feed. Once they feed 1 becomes 2, 2 becomes 4, etc this happens every 20 - 30 minutes. At the end of 12 hours you have in excess of 8 million. As far the the pH concerns. If it exceeds 7.5 you are entering a danger area. It usually starts to burn around 8.0.
