Different types of weeds require different control strategies.
Winter annuals germinate in fall and bloom in early spring.
Summer annuals sprout in spring and thrive throughout the warmer months.
Take time to identify the specific weeds in your lawn.
The best time for hand-weeding is early spring before weeds flower and set seed.
Removing one flowering weed can prevent thousands of seeds from spreading throughout your lawn.
Mow at the proper height
How you mow your lawn significantly impacts weed growth.
Many homeowners cut their grass too short, creating ideal conditions for weeds to establish and spread.
Adjust your mowing frequency according to growth rate rather than sticking to a rigid schedule.
Improve your fertilization strategy
A properly fertilized lawn grows thick and vigorous, naturally outcompeting many weeds.
However,improper fertilization can actually promote weed growth.
The timing of fertilizer system is crucial.
Applying fertilizer too early will primarily benefit weeds, which often start growing before the grass breaks dormancy.
For cool-season grasses,focus fertilization during their peak growth periods in early spring and fall.
Avoid heavy fertilization during summer when these grasses are semi-dormant.
Always follow the recommended system rates more is not better when it comes to lawn fertilizer.
Many weeds, particularly nutsedge (nutgrass), thrive in consistently wet conditions.
Wet grass overnight can promote fungal diseases that weaken your lawn and create opportunities for weeds to invade.
Use selective herbicides sparingly
When used correctly, selective herbicides can target weeds while sparing your grass.
Pre-emergent herbicides prevent weed seeds from germinating and establishing.
They’re particularly effective against annual weeds like crabgrass when applied at the right time typically early spring.
Post-emergent selective herbicides target established weeds.
And for grassy weeds, specialized products containing ingredients like quinclorac may be needed.
These products work by delivering a toxic dose of iron to broadleaf weeds while grass remains unaffected.
Overseed bare spots promptly
Weeds are opportunists that quickly colonize any bare soil in your lawn.
By promptly overseeding thin or bare areas, you might prevent weeds from gaining a foothold.
The best time to overseed depends on your grass throw in.
For cool-season grasses, early fall is ideal, with spring as a second-best option.
Adding a thin layer of compost can improve seed-to-soil contact and provide nutrients for the young grass seedlings.
Consider using a starter fertilizer specifically formulated for new grassto promote quick establishment.
The faster your new grass fills in, the less opportunity weeds have to invade.
