Find the Best Weed Killer for Lawns By First Finding out about Different Kinds of Lawn Weeds


Broadleaf weeds are also known as dicots. They have flat weeds that can absorb a lot of sunlight. Further most part, broad leaf weeds are easier to control. Some types of Broadleaf weeds are very easy to identify. For instance, a dandelion is a very common type of Broadleaf weed. It has broad leaves and yellow flowers. It is pretty easy to distinguish from ordinary grass. Other weeds, can include grasses. Basically, we need is anything that disrupts the way that your lawn looks.

Grassy Lawn Weeds

Grass weeds are also known as monocots. In a lot of ways these will resemble your grasses. They may include several different types of weeds from crabgrass to crabgrass, and they even include sedges. Almost all other types of weeds are considered broad leaf. Perennial grasses are among some of the most difficult weeds to control. Typically you want to use a pre-emergence that prevents crabgrass in order to prevent it from coming into your lawn. You want to make sure that you put a pre-emergence down before the grass starts growing. Once it starts growing, you may need to use non-selective (kills everything) pesticides and spray them and then dig them out.


Best Types of Weed Killer for Lawns and Weed Killer Classifications



If you're looking for a weed killer for lawns, the first thing that you should know is that there are basically only two types of weed control.  These two types are known as post emergence, and pre-emergence.

Pre-emergence is easier to define. Basically it is a herbicide that you apply in order to prevent weeds. If you tend to get weeds every year, you should try using a pre-emergence.  A pre-emergence can reduce the number of annual weeds that you get, and the number of perennial weeds that would otherwise germinate from seed.

Post emergence weed killers include four basic categories. These categories include contact weed killers, systematic weed killers, nonselective, and selective weed killer for lawns.

 A contact weed killer is the first type of weed killer for lawns that most people think of. A contact weed killer will kill everything that it comes in contact with, but nothing else. When it comes into contact with the weeds, it is toxic to the weeds and will eventually kill them. It works great with weeds that don't have very deep roots or tubers.

The next type of weed killer for lawns is a systematic weed killer.  Most weed killers that are available for sale at your local home improvement center, are systematic. This means that they have to be taken in by the plant in order to destroy it. Systematic lawn weed killers are very effective with broadleaf weeds and are probably the best weed killer for lawns that you can use.

Then, you have your selective pesticides.These type of herbicides are specifically designed to treat one variety or one kind of weed.  Selective pesticides are great to use when you want to kill a grass weed without killing the grass in your lawn. A lot of times, they're used on grass sedges. In addition, they can be very effective at killing certain types of broadleaf weeds if that is what they are specifically designed for.

The last type of herbicide or lawn weed killer for lawns is a nonselective pesticide. This will kill everything. You might even find a nonselective pesticide combined with a pre-emergence. Nonselective pesticides will kill anything that they are sprayed on. Some of them can be used to keep weeds from growing in a specific area. Nonselective pesticides are generally the strongest and the most toxic. This is generally not used for lawn weed control if avoidable.



Use Hand Pulling to Kill Weeds Quickly

One of the fastest ways to help your lawn get rid of weeds is to just go out and pull some weeds.  Usually the first generation of weeds to come into your lawn is easy to control if you don't allow them to seed.  As soon as you notice that you have weeds in your lawn, it is a good idea to take care of them right away. Some weeds can literally produce thousands of seeds every year. You want to make sure to take them out before they go to seed. For instance, it the best time to pull a dandelion any time before the yellow flower turns white. If you do not go through the trouble to take care of weeds growing in your lawn today, then you may have to face the battle later on when they are a lot more numerous.


The Best Defense against Weeds Is a Healthy- Organic Lawn Weed Control

Lawn weeds can be quite aggressive, and if your lawn shows any signs of weakness, they can creep in and slowly take over. By having a healthy lawn, you can help keep your grass healthy and help keep weeds out.  To keep your lawn healthy, you need to make sure that you only mow one third of the grass blades every time you mow. You also need to make sure that you water your lawn on a regular basis, but not too often. Also, you need to make sure that you apply fertilizer in the spring and in the fall. The last thing that you can do to have a healthy lawn free of weeds is to aerate your soil so that your grass roots can grow deeper. If you can strengthen your lawn, you won't have to use weed killer for lawns nearly as often.

Use Mowing and Watering to Strengthen Your Lawn

The best way to defend against weeds is to mow your lawn a little bit taller than you normally do.  (This picture is too short!)  If you mow your lawn too short, you are going to attract weeds just because your lawn does not provide as protective of a barrier against them. If you mow your lawn too long, then your grass will start to get sparse, and you also develop weeds. Most types of grass are cut at a height of 2 inches. If you can grow your lawn out to 2 ½ inches, it will be a much better way to protect your lawn from getting weeds. Likewise, if you get too much water on your lawn, it will slow down the growth of your grass and put extra stress on your root system. In addition, This will attract certain types of weeds that like very wet soil conditions. On the other hand, if you don't water your lawn enough, your grass may start to die out, and it will be replaced by weeds that do well even when they don't get very much water.  If you can keep your lawn growing vigorously, there isn't as much of a chance that you will have to use a lawn weed killer later on.
