Are you sure it's mold or fungus and not spider mites? They can cause a very heavy white 'mold' looking infestation. I doubt the CS will do anything to them. The peroxide might. Usually you just take the plant outside and hit all the underside leaves with a heavy spray of water from a hose. Or you can wash each leaf off by hand in the house. They do have spider mite spray, but that's toxic. Maybe now they have a natural one as it's been years since I've had to deal with spider mites.
Samala, Renee -------Original Message------- There is a newly planted tree in my home, about 5 feet high, with white mold/fungus growing on the bottom side of most of the leaves. I have been spraying it with CS and peroxide, and it has improved, but I want to know if dumping jars of CS in the dirt actually helps it internally?
