How Do Weed Killers work?
Most of the time, we use pre-emergent weed killers to kill weeds on grass. This type of chemical-based herbicide either comes in liquids type or granules type. However, using water for both versions is necessary to allow them to work efficiently.
So, how do these weed preventers work? When you apply the solution to the soil, they leave a residual substance on top of the soil (around 1-inch of the ground).
The germination process of seeds occurs either below the soil or top level of the ground. The weed preventer works efficiently to prevent the weeds from germination as much as possible through its active ingredients. It can last up to 4 months. However, it depends on the type of weed killer you have used on the ground.
But the problem is that some grasses also fail to germinate like weeds. Thus, their growth is compromised. That's why choosing selective weed killers is necessary to ensure no harm to the grass.
When to Apply Weed Preventer on Lawns?
The spring season is the best time. Grasses are mainly available in two varieties: warm-season and cool-season. Turfgrasses are mostly called warm-season grasses, which are already grown. On the contrary, cool-weather grasses can grow through seeds.
The fall season is the best time to sow seeds of cool-season grasses as they can germinate efficiently during the period. After growing the grass, you want to choose either spring or summer to use a weed killer. This is the best time to kill weeds within a short time.
Keeping the temperature between 65 to 70 degrees Fahrenheit is a good rule of thumb while applying the weed preventer. Avoid choosing high-temperature days because the chemical may vapor to the surrounding environment. It decreases their efficiency.

You think your job is done after choosing a perfect time schedule to sow grass seeds? NO! Correctly seeding grass seeds is more important. You want to ensure no unfinished patches.
Choose a perfect mild fall day and sow the grass seeds evenly using a drop spreader. After applying seeds, create 1-inch of mulch over the seeds. It retains moisture and helps to germinate.
Watering the grass seeds at least two times is necessary. Each watering session should be around 10 minutes. Consistent moisture is essential for their optimal growth. However, make sure you don't overwater the seeds. Otherwise, the seeds will be flushed away.
If you notice any young weeds while the seeds are growing, root out them using your hands. Avoid using any chemical weed killers to control them.
How to Keep Grass Seeds Healthy?
When your new grass is healthy and robust, weeds are less likely to affect them. Thus, using weed killers won't be necessary.
When the grass becomes grown-up, you don't need to water them regularly. Instead, watering them one time a week is enough, especially in the growing season. Make sure the water doesn't reach more than 1-inch of the upper layer. It is perfect to create strong grassroots.
When grasses grow in unfavored environments such as drought, their roots may die. Additionally, roots may also die if weeds are increasing in a narrowed area.
That's why you want to keep your grass at an ideal height, ranging between 1 and 3 inches. But it depends on their species. Elongated grass halm is a sign of healthy grass. They can generate sufficient energy from the root system and fight against weeds.
How Long Should You Wait To Put Weed Killer On Your Lawn After Planting Grass Seed?
It depends on which type of weed killer you are using and the kind of weed you want to kill. If you are using a chemical-based weed killer, read the product label carefully.
