If you don’t like using
chemical treatments for weeds,
try using this natural recipe
for weed killer:

If it is over 85 degrees
do not spray your weeds either
chemical or natural solutions as
the weeds plant cells close
and do not absorb anything.
Spraying early in the morning to
avoid the heat is the best time.
It’s
been the perfect storm for
Colorado’s tough weeds, with
an early spring and just
enough hand-watering and
natural
precipitation to germinate
seeds.
If
you’re down for the fight
and fixing to win, arm
yourself with these seven
strategic bits of
info.
•
Fertilizer needs to be in
your arsenal. According to
researchers at Colorado
State University, weeds
thrive even
better in lawns that are not
fertilized. A healthy lawn
crowds out weeds, and part
of building a healthy lawn
is proper
fertilization.
•
Drying out weeds won’t help
you kill them. Again
according to CSU,
drought-stressed weeds may
look like they are
about to die, but they
aren’t. They’ve evolved to
thwart drought. But the
healthier that weeds are,
the easier they are to
control because healthy
weeds are better able to
take in anything you put on
them.
•
Know your weed before you
pull it. If the numbers are
manageable, many can simply
be dug out. Other weeds,
such
as bindweed and thistle,
generally should not be
pulled because their roots
grow deep. Pulling these
weeds just activates their
regenerative root systems to
start more growth. (If
you’re trying to fight
bindweed naturally, cut
it.)
•
If you apply a weed
treatment, know its
limitations. Here are two
critical distinctions among
weed-zapping
products:
Selective
products are effective
because they’re designed to
select certain plant traits
to work on, such as
broadleaf
weeds. These products are
effective on dandelions
(broad leaves) in the lawn
because they deal with the
dandelions and don’t harm
the grass (thin
blades/leaves).
Nonselective
products will zap any plant
they contact. So if you use
a product like Roundup — or
one of the newer
horticultural vinegars — you
need to know that they will
affect both the dandelion
and the lawn.
•
For any product, follow the
label. Find out what the
product is good for and
where it might do more harm
than good.
If you use a product that
requires mixing with water,
don’t assume more is better.
According to USDA scientists
who do testing, using more
product is usually less
effective than the
recommended amount.
•
Is there a breeze? Whatever
treatment you use, beware of
it drifting even in a slight
waft.
•
The best strategy in the
weed war is to be always on
the offensive. The more
proactive you are in the
battle against
weeds, the better your
success. Treating weeds
early and effectively,
before they develop and
disperse seeds — sometimes
tens of thousands of them —
gets the best
control.
