Question
I have moss growing on the roof of my garage. Can I spray it with something that will kill it. With all the rain we've been having, it seems to be spreading quite quickly.

Answer
Hi Darlene;
Yep, you can use a fungicide, if you don't want to use a chemical, use baking soda disolved in water.
Disolve about 4 teaspoons per gallon of water. Put it in a garden sprayer and spray until the area is saturated.
If you can trim trees or remove whatever causes shade to the area, so sun can get to it, when there is sunshine, that will help kill it and kep it away.
The baking soda will kill it. You may have to apply more than once, if there is still a lot of moisture and no sun.
