5 Reasons Why Corn Gluten Meal Didn’t Work – Organic Weed Control – Organo Lawn

Hi I’m Brad Wolfe with Organo-Lawn and
today we’re going to talk about some of the
reasons that a corn gluten meal
application may have not worked on your
lawn. If you are not familiar with corn
gluten meal
it is a natural pre-emergent weed
control and fertilizer that prevents
weed seeds from germinating properly. At
Organo-Lawn we have a custom blended corn
gluten meal product called Synergy that
gets excellent results. Every now and
then we field a comment from someone
saying that corn gluten meal didn’t work.
There are five main reasons that
do-it-yourselfers struggle with corn
gluten meal applications. These reasons
are that the application rate is very
heavy, timing is important, there are two
types of corn gluten meal, bonding agents
effect performance, and a lack of
understanding how corn gluten meal works.
First the application rate of corn
gluten meal is 20 pounds per thousand
square feet. This is a very heavy
application rate and most spreaders are
not capable of applying at this heavy
rate. If corn gluten meal is applied at
less than 20 pounds per thousand square
feet, than it will only fertilize the
lawn and will not have any weed control
effects. The second reason a corn gluten
meal application may have not been
effective is that it was not applied
early enough in the season. Corn gluten
meal prevents weed seeds from
germinating properly, so it needs to be
applied prior to the weed seeds germinating.
Sometimes people start to see dandelions
growing in their yard and then they
apply the corn gluten meal. If weeds are
already growing in the lawn it’s too
late for the product to work properly. We
prefer to apply our products Synergy to a
lawn in March. March is too cold for
sprinklers to be turned on so if Mother
Nature doesn’t provide natural moisture
we ask our customers to water the
Synergy application the old-fashioned way;
via hose and a sprinkler. The third
reason why a corn gluten meal
application may have had poor results, is
there are actually two different types
of corn gluten meal. There is a 20
percent protein based corn gluten meal
and then there is a 60 percent protein
based corn gluten meal.
The 20 percent corn gluten meal needs to
be applied at 60 pounds per thousand
square feet to control weeds. Where the 60% corn
gluten meal needs to be applied at 20
pounds per thousand square feet. Our
products energy is a 60% corn gluten
meal product. The fourth reason that a
corn gluten meal application may have
not been effective is that many corn
gluten meal products are bonded using a
non water-soluble agent. Corn gluten meal
as a powder and to make it spreadable it
needs to be turned into a pellet. Most
corn gluten meal products use a very
strong bonding agent and if the bonding
agent does not release the corn gluten
meal after it is watered, it stays in a
pellet form. In our product Synergy we
use sugar as a bonding agent. Sugar is
very water soluble and Synergy will
break down quickly after it comes in
contact with water. The fifth and final
reason that a corn gluten meal
application may have not been effective,
is that many people don’t actually
understand how corn gluten meal works.
Corn gluten meal is a pre-emergent weed
control that prevents weed seeds from
germinating properly. Many weeds are
perennial or biennial weeds that
germinate from an existing root system. A
dandelion is a good example of a weed
that germinates from seed the very first
year, and then after that, it germinates
from an existing root system. Therefore
corn gluten meal will prevent new
dandelion seeds from germinating, but it
will not prevent dandelions that are
germinating from an existing root system.
We typically see around a 60% weed
control rate after the very first
application of corn gluten meal. If a
quality corn gluten meal product like
Synergy is applied at the correct
application rate, at the right time of
year, for four or more years; the weed
control rates will be excellent.
We recommend spring and fall
applications of Synergy for best results
in your lawn. For more lawn care tips or
