#1 – Target your WEED at the right time.
You apply a pre-emergent based on the weeds you want to PREVENT for the next 3-5 months. Example: There is no reason to worry about CRABGRASS in the late fall, going into winter, but you would want to target Poa Annua and other winter weeds / grasses. However, you WOULD want to make sure your preemergent stopped crabgrass when putting down in March or April. (based on your zone).
#2 – Many liquid pre-emergents cover a broad spectrum
Many products listed below will cover a broad spectrum of target weeds. So make sure you read the label and make sure your TARGET weed is covered. They often cover crabgrass even though you are not targeting it. (Such as fall and winter) But that’s OK… they’ll stop those darn winter weeds like chickweed and poa annua.
#3 – Vary using both light treatments of granular and spray for best results.
We have found the best results from applying at a LOW RATE of each listed on the label. You can space these out a few weeks in-between. Example… a low rate of granular early in the spring / late winter and then a LOW RATE of the liquid right on time a few weeks later. Generally you only need one treatment in the fall. By law… you have to follow the label which means you may be limited to “X” number of applications or maximum rates per year. Finding a BROAD SPECTRUM granular is not easy.
#4 – DO NOT OVER APPLY or APPLY TO NEW SOD
We try to write these instructions at an “8th grade reading level”… but some have suggested that we say OVER APPLY pre-emergents. That is NOT what we are saying. Apply ONE chemical in granular form lightly… then come back a few weeks later and apply a different spray chemical LIGHTLY. Example: Barricade DG then Dimension (shown below).
PRE-EMERGENTS stop seeds from developing and inhibit new root growth at a shallow level. (1-2″) The chemical stops cell division in the plant, either root or shoot, preventing it from reaching the soil surface and sunlight. New sod should never have pre-emergent applied. We suggest a FULL YEAR of growth before using light treatments on NEW SOD. Instead use a post emergent to control weeds and be patient.
#5 Do not apply if you plan to SEED your lawn.
Pre-emergents stop seeds from growing. You’ll generally have to wait 4 months before trying to seed your lawn.
For most people the target soil temp we want to watch for is 50 degrees.

This is Doc’s #1 choice for pre-emergent in granular form. It’s the broadest spectrum pre-emergent and the technology used in the granules is AMAZING. This product features Dispersing Granule (DG) Technology. Upon contact with water, each DG granule disperses into thousands of microparticles that move through the turf canopy into the root zone.
This is a 50 pound bag and will Doc puts it out at roughly 3.5 lbs per 1000 sq ft in the fall. Then later follows up with a liquid. WATCH THE VIDEO
