Weeds that are visible should be treated with a post-emergent.
The majority of weeds can be kept out with a pre-emergent.
It is very possible if you do not use the right weed killer for your lawn.
We like to classify them as annual or perennial and broadleaf or grassy.
Get rid of weeds in my lawn
Weeds that are visible in your lawn are treated with a post-emergent weed control. This is as simple as it sounds, the weed have already (post) grown (emerged). There are many off-the-shelf products available, but it is important to consider using the services of a turf and ornamental professional. The majority of the products sold over-the-counter are very diluted and do not have the desired effect.
Keep weeds out of my lawn
To prevent weeds from appearing in your lawn, a pre-emergent weed control is needed. Pre-emergent is applied in late winter/ early spring and again in the fall. It is needed at least twice per year because different weeds grow at different times.
Types of weeds
There are several ways to classify weeds. The simplest way to break these down is into two sets of two:
- Annual weeds
- Perennial weeds
Just like beautiful flowers planted in the landscape, weeds come in an annual and perennial varieties. An example of an annual weed is crabgrass, while dallisgrass is considered a perennial.
Clover and plantains are an example of a broadleaf weed, and the two weeds mentioned earlier are considered grassy weeds. So, a weeds can belong to two groups, crabgrass and dallisgrass are both grassy weeds, but one can be an annual and the other a perennial. This is why it is important to not just spray or spread something you buy at Lowe’s or the local garden store without knowing what type of weed you are treating and even more importantly, what type of grass you have or want.
Can I kill my grass with weed killer?
The short answer is absolutely. The are four main types of grass in our area and there are products that can be used on some and not the others. Weed killer that can be used on bermuda may or may not be safe for centipede, and the same is true the other way around. Again, consider using the services of a professional. This ensures only the proper weed control is used and in the proper dosage rates.
