    Hard to advise because there are different fungi that plants are susceptible to. If your plants are in pots, make sure they are not getting too much water and are draining well. Cut away the leaves that are showing the fungus. You can gently wash the leaves of your plants with a solution of water and a little baby shampoo in a spray bottle. It won't hurt the roots if it goes into the soil. I have heard of applying Vicks Vaporub directly onto the affected leaves, but have no personal experience. I use Neem oil spray, which is an organic product and is even safe for plants that produce fruit. Expect to keep going back to spray for a few weeks, and still cut off the leaves with visible fungus. Feed your plants also.

    Sometimes fungus or mildew will form on plants that don't get enough air circulation around them; the key is to 'open up' the area so that there is more air movement among the plants & then the mildew/fungus/mold will disappear. You may want to add lime to the soil to 'sweeten' it...especially if you notice that you have a lot of buttercups growing in the area...[they love moisture & acidic soil].
