=D (> .. <) (>*o*)> 8o <..
One Big problem with black mulch is that sometimes the
dyes or chemicals in the wood leech the plants ( suck the
life out of plants)
According to several studies conducted by the
SoloGabirele and Townsend, Tolaymat and Blassino, in
1999 to 2002 they were studying black mulch to see what
is in it. What they found was chromatic copper arsenic.
ALSO mercury .=D
What is mulch used for?!?!?!?!?!? +
Mulch is to make all of the flowers in you garden
look wonderful. Mulch can also be used to cover
something up that you do not like about your
garden. There are other things that you could do
with mulch but there is to much to talk about.=D
Chemicals Harmful to Fish
Black mulch is the color of the mulch in the courtyard. Black
mulch must be dyed to get its' color, so a natural color, such as
brown, would be a better choice of color to keep the pond safe.
Mercury is a byproduct of coal, the most common dyeing
material of black mulch. Mercury is a very harmful material and
can poison the fish.
Mulch is also full of preservitives, all of which rub off in the rain
or sun, leaking into the pond and harming fish.
What Are Black Mulch Dyeing
Ingredients?
• Most common mulch ingredient is coal.
• Water-based paints and natural vegetable dyes are
also commonly used.
• Black mulch also includes dyes made from materials
created by incomplete petroleum combustion. Also this
type of dye should be avoided from plants because it
can be both harmful and dangerous.
Risks of Black Mulch!
Some factories use chromae copper arsenate ( a
toxic element to garden plants an other living things
Also some black Mulch that contains plastic will
also contain zinc, benzene, and other potentially
harmful substances.
Thats why some scientist think it's best to use raw
mulch so you know it's been naturally made.
Do you know what Mulch Is?
Mulch is any material used to prevent weed growth and to
gain soil moisture.
It's shredded wood, straw, leaves or a man made material
like shredded tires.
Black Mulch does not have to do with any scientific facts it's
just to make your yard look nicer.
However, whatever mulch you put on your lawn and garden
will wear down and make up for he soil. Because of this black
mulch may include ingredients that some gardeners try to
avoid.
