Make mulch dye by combining 16 ounces of mulch colorant or one 12-ounce bottle of mulch dye and 1 1/2 gallons of water in a bucket and mixing the ingredients together thoroughly with a paint stirrer. Wear old clothing and protective gloves to prevent the dye from staining your skin.
Once the mulch dye is mixed, pour it into a garden sprayer. Ensure the mulch is spread out over the area desired and that all plants, buildings, sidewalks and stones are protected with plastic sheeting. For an area larger than 200 square feet, double the amount of water and colorant used. Spray the dye onto the mulch at a distance of 6 inches in even rows for a consistent color. Once one section is covered, move on to another area.
Dying mulch instead of buying colored mulch in a store is a more cost-friendly method. Furthermore, this method provides a greater choice of shades and colors. Not only is mulch aesthetically pleasing, pulling a yard together or adding an elegant touch, but it also helps plants. Mulching over winter keeps plants that are sensitive to the cold warm and toasty during their dormant period. Mulching during the planting season keeps soil moist and cool for improved growing.
