Applying Weed Killer To A New Lawn
New lawns are more sensitive to herbicides than established lawns. Don’t apply pre-emergent weed killer to a newly seeded lawn. When the grass has an established root system, you can safely apply a pre-emergent herbicide product that contains dinitroaniline. Additionally, in spring, you can apply a product that contains pendimethalin to a lawn that was seeded in fall, after the lawn has been mowed four times.
When applying a post-emergent herbicide to a new lawn, again, wait until the lawn has been mowed four times. If the lawn is newly sprigged, wait until the sprigs are rooted and growing. Apply the weed killer at half the rate recommended on the label, and reapply the product seven to 10 days later to treat weeds that may have survived the first application.

While certain weeds are easy to control and can be knocked back with just one treatment, other weeds are a bit more persistent and may require multiple treatments. While we wish we could say that once we treat weeds, theyll never return, thats simply not the case.

Types Of Different Weed Killers: How To Apply Them At The Proper Time
Herbicides are recognized either as pre-emergent or post-emergent. Post-emergent herbicides, which may be systemic or non-systemic, are used to control existing weeds. Herbicides that pass through vegetation to the roots are known as systemic herbicides, and theyre most successful while the plants are actively developing.
Plant tissues are damaged by non-systemic herbicides, which can be spread at any time of day. Pre-emergent herbicides may be used at any time of day and are still effective. This herbicide works by forming a chemical membrane in the topsoil that keeps weeds out.
1) When to apply a systemic herbicide
Systemic weed killers are most effective throughout the planting season, and they are ineffective after the weeds have finished growing and gone dormant. The efficacy of systemic herbicides is increased when they are applied at peak plant growth periods during the day. Plant development speeds up and reduces during the day, based on the amount of sun, temperature, and environment.
In warmer climates, such as the U.S. Department of Agriculture plant hardiness zones 9 and higher, the safest hours to apply systemic herbicides in the summer are early morning and late afternoon. In the season, avoid using herbicides during midday or early afternoon. Plant development slows during the midday sun, and herbicides soon dry out on the plants, decreases the quantity of herbicide that weeds absorb.
