Dyed Mulch Can Be Safe to Use, Depending on Source of Wood
But the dye on colored mulch is less of an issue than the type of wood on which the dye is applied. Dyes used in making colored mulch have three different origins, and all three are harmless: Red mulch is dyed with iron oxide.
Besides, what kind of dye is used to color mulch?
The dyes used in coloring wood mulch are primarily of two types: carbon-based dyes and iron oxide based dyes. Iron oxide, the most commonly used dye, is simply a compound of iron and oxygen.
- Choose a day to color wood chips when the wind is calm.
- Pour water into a garden sprayer, add the mulch dye and mix the ingredients by shaking or stirring the solution with a paint stirrer.
- Point the garden sprayer's nozzle at the wood-chip mulch that is at one end of a plant bed.
Correspondingly, how do I keep the color in my mulch?
How to Maintain Mulch
- Refresh Mulch Color. Over time, mulch colors fade due to frequent exposure to sunlight.
- Remove Weeds. Despite mulch's amazing ability to ward off weeds, they still manage to emerge now and then.
- Mix and Turn Mulch.
- Mulch Twice a Year.
- Keep Mulch From Washing Away.
Red dye used in modern mulches is made from iron oxide, a material deemed safe for use around pets and humans. It can actually help your soil by adding small amounts of iron as the mulch decomposes. Organically dyed mulch typically uses vegetable dyes, which pose no harm to your garden.
