1. Watering-in treatments correctly as advised on the E-Doorhanger sent to you after each treatment. Watering too little, too much or waiting too long can all compromise the weed control results. Waiting on rainfall is not recommended. Rainfall can wash away weed spray & fertilizer or worse, force the pre-emergent too deep into the rootzone of the turfgrass which can cause turf damage. Gentle irrigation is much preferred to unpredictable rainfall.
When irrigated correctly, the
pre-emergent can get to the exact depth required and then dries and bonds to
the soil creating a weed prevention barrier – this is how it’s done.
2. Avoid mowing with dirty/weedy mowers. Even lawn
mowing services can bring in unwanted weeds. The best way is to use your own
mower and don’t mow weeds with it, keep it clean & uncontaminated.
3. Turf must be healthy enough to pose natural competition to
weeds. Be sure it’s not being suppressed by:
Grubs/insects, lack of sunlight, soil compaction, soil
infertility, poor drainage, soil movement. Have us do a soil test.
4. Take what
measures you can to reduce high weed pressure from surrounding areas.
5. Avoid over watering (includes rainfall) which prematurely washes away & dilutes the weed preventing active ingredients in the pre-emergent. Over watering causes weed problems like “Nut-Sedge” & “Crabgrass” & other hard to kill weeds. See our season-long water guide
