Hi Bonnie,
If in trimming the leaves you are not eliminating a large proportion of leaves that is a good idea. Disinfecting the tool should also be done. Without seeing the spots, it is difficult to say what the treatment should be; however, if it appears to be a fungal or bacterial, applying a copper-based fungicide is a good idea. Fungicides work best as preventatives but in most cases, this will at least slow the progression. Avoid overhead watering. Check out the following links:

I hope this helps.
