Were working on spraying fertilizer on a new project in a cemetery. Will Liquid Nitrogen or Liquid iron discolor or make the metal on the granite markers brittle or possibly break. Labels don't cover this and need some help on this one.

Thanks Guys

I don't think the fert will be a problem but I wouldn't spray anything with the iron. It can stain.

The liquid Iron that Lesco sells is a fabolous product and makes the lawns very green especially during the warmer months and YES and i repeat YES it will stain everything you miss such as concrete walkways, houses, and of course the applicators gotta wear gloves so be real careful and the product is fairly inexpensive too.
