Helping Mulch Hold Color
Mulch that loses its color too fast may cause the producer to lose customers.
The primary reason colored mulch fades is low colorant application rates. If producers use too little mulch colorant, the product will appear faded more quickly.
It's also important to properly mix the tote of mulch colorant prior to use to ensure the right concentration is applied throughout the tote.
A proper mulch colorant rate will result in good coverage on the substrate and stand up to the different weather we face around the country. If the mulch colorant is spread thinly on the substrate due to a low application rate, it will not withstand the weather elements.
If you're in regions known for certain types of weather, here are other steps you can take to protect the durability of your colored mulch in your climate:
In states like Florida, water application is important. One factor is the moisture content of the raw material. Also, when coloring after rain, water levels should be adjusted accordingly.
If you're in an area with lots of rain, the challenge is keeping the material dry. Many customers in the Pacific Northwest, for example, put material under a roof or pole barn to help in the drying process.
It's helpful to pre-wet material in dry weather. Water is the carrying agent for the mulch colorant, and you may need to increase water rates if the wood is very dry.
