Why You Need Pre-Emergent Weed Spray Service
                     WHY YOU NEED 
PRE-EMERGENT
WEED SPRAY
SERVICE
Effective weed control often 
requires addressing problems 
before they become visible. 
Many property owners aren’t 
aware that they can get a handle 
on weeds long before they appear 
on the ground. 
Pre-emergent spraying offers 
benefits that you’ll realize 
when everyone else’s weeds 
start to sprout.
WHAT IS 
PRE-EMERGENT 
SPRAYING?
A pre-emergent spray is simply 
one that we apply before the plants 
are actively growing. 
This type of spray contains a special 
herbicide that targets the seed.
Once it hits the seed, it coats 
the outer shell and stops 
it from sprouting. 
Rendering the sprout incapable 
of growing means that you won’t 
see it emerge from the ground.
DEAL WITH 
LAST YEAR’S 
WEEDS BEFORE 
THEY SPROUT
You might have thought you had the 
weeds under control after spraying 
during the active growing season. 
Post-emergent sprays are great for 
helping to improve the appearance 
and health of your lawn, but there 
may still be seeds from your old 
weed problem just waiting to sprout. 
Stopping them now helps to keep 
last year’s problem from 
becoming this year’s new one.
STOP 
PLANTS FROM 
SPREADING 
SEEDS
Pre-emergent spraying ends 
the constant cycle of having new 
weeds popping up. 
Killing the weeds before they have 
a chance to reproduce lowers 
the number of seeds that wind up 
in your lawn. 
With fewer seeds, you’ll naturally 
see fewer weeds, so you can enjoy 
a weed-free lawn for longer.
GIVE YOUR LAWN 
A STRONG 
HEAD START 
ON GROWTH
Weeds are more than just 
an eyesore. 
They also have a negative impact 
on the surrounding desirable plants.
Preventing the weeds from 
growing gives your lawn a better 
chance of reestablishing its growth 
after the winter season. 
You’ll also benefit from knowing 
that water and fertilizer is going 
straight to the grass rather than 
feeding the weeds.
PREVENT 
SEASONAL 
ALLERGIES 
AND OTHER 
HEALTH ISSUES
Many weeds are toxic or irritating 
to humans and animals. 
Ragweed is a common allergen 
that tends to cause the most 
problems in the spring and fall. 
Russian thistle is another weed 
that can cause skin rashes along 
with respiratory symptoms. 
WHEN SHOULD 
YOU APPLY 
A PRE-EMERGENT 
SPRAY?
Timing is an important element 
of every landscaping 
maintenance plan. 
We don’t typically recommend 
a specific date for applying 
pre-emergent sprays.
Instead, we pay attention 
to the weather. 
We can start doing pre-emergent 
treatments after the last frost 
of the season.
This helps us to hit the weed seeds 
just as they are starting to grow.
WHAT HAPPENS 
IF YOU STILL 
SEE WEEDS?
Professional spraying takes the 
guesswork out of weed control. 
Our technicians know how 
to evenly apply the spray so that 
it reaches the important parts 
of your lawn.
Still, you might see some weeds 
pop up over time. 
If they do, you may need to plan 
for a post-emergent spray that 
targets actively growing plants.
It’s that time of year again when 
you may already be planning 
for how to care for your lawn.
