Rain does affect the color of your dyed mulch/chips. If it looks like rain, consider waiting. The dye can leach color from your mulch and stain your driveway. The dye will come up with soap/water and a good bristle brush. Crossroads Property Services is not responsible for washed out bark or dying of your driveway. We recommend using a tarp when using dyed products and for all products to make clean up easier.
