This is great for mark making and lovely outdoor play on a hot day! So simple, no clean up! Fill up a trug with water, add mops, brushes, brooms, sponges, spray bottles. Sit back while your children play. Dipping their tools in and making marks all over the garden/pavement/shed. :)
Combine: 1 teaspoon baking soda 1 quart water A few drops of liquid soap Combine in a large container and transfer some to a spray bottle. Spray the leaves of plants where powdery mildew can be seen, then repeat a week later. For best results, treat plants as soon as you notice the powdery mildew.
