crab grass killer Buyer’s Guide
Weed killer concentrate
Most weed killers come in form of a concentrate that requires dilution. The level of concentration determines the quantity of the solution that can be made out of a unit. For instance, most weed killers have a concentration level of gallon to 8gallons of water which can treat about 25,000 square feet piece of land. However, the level of concentration varies with the price, therefore, the stronger the concentration the more expensive it is. On the same note, even though the highly concentrated are very effective, they are a bit dangerous and require a proper handling.
Organic vs Inorganic
The main difference between organic and inorganic weed killer is that the organic is made from natural ingredients whereas inorganic are produced by humans in the laboratory set up. The organic works by waxing the cuticles that results to dehydration since the cuticles in plants cells helps in maintaining the water supply in the plant. On the other hand, the inorganic have chemicals that literally burn the leaves and roots of the weeds making the plant cells to dry.

How to apply liquid weed killer on your lawn
Applying liquid weed killer is not very difficult but you can expect to take a few hours for the average yard. Additionally you have two choices you can make when applying liquid weed killer. The traditional method which I use means buying concentrate weed killer and diluting it in a garden sprayer.
When you use a garden sprayer for killing weeds on your entire lawn you want to buy a canister that is large enough to carry a good amount of solution and one that is small enough that you are not throwing your back out as you are carrying it for a few hours.
I like to buy the gallon sized sprayers because they give me the best weight to benefit ratio. Honestly if you carry a two gallon container around your yard for a few hours it will begin to pull on your shoulder and back so you might want to go with a smaller 1.gallon or even a gallon or you can buy the larger gallon one and only fill it half way.
Once you find the right brand of concentrate you can dilute it and apply it.
I always cut my lawn before I begin applying any weed killer and then do not cut it for at least days. It will take at least days for the weeds to start browning up and letting you know the killer is doing its work. You want to leave it on the weed as long as you can so it gets sucked down into the roots.
I suggest that you pick a point in the corner of your yard and walk backwards as you apply the weed killer. This will reduce the amount of overspray that gets on your face, legs, clothes and shoes. It is best to find the wind direction too and start at the point in your yard where wind is blowing away and walk back from there.
Concentrate in a garden hose adapter is another choice. It eliminates the need to purchase a garden sprayer. This is an option for many people but I do not like the fact that so much water is used during the application. I have found much better results with a concentrate and sprayer however this method goes much faster and could be used on lawns that are in serious trouble just to get the weed killing process started.
Natural Crabgrass Control Methods
As was mentioned at the beginning, the best crabgrass control is having a healthy, well-established lawn. By fertilizing in the spring and fall, with a heavier fall application, your cool season grasses will be able to grow well enough to smother out any crabgrass seedlings that are able to get started. Maintaining your lawn by immediately filling any bare spots will help keep crabgrass at bay.
Because crabgrass has shallow roots, irrigating with more water less frequently will provide plenty of water for your desired grass while depriving crabgrass of the water it needs. These shorter roots also help make hand weeding work well as a control method. Watering the lawn before hand weeding makes it much easier to get up as much of the plant as possible.
Organic Crabgrass Control Methods
Beyond natural means, there are other organic means that can be used to help control crabgrass. If you need to completely replant your yard, taking black plastic and covering the ground, especially during the hot times of the year, will bake any weed seeds left in your soil and leave them unable to grow.
Another common organic method is using corn gluten meal as a pre-emergent, which will not only control the crabgrass by absorbing moisture away from the seed, but also provides fertilizer for your lawn and landscaping plants. Like any pre-emergent, it needs to be put down at the right time, just as the chemical pre-emergent treatments above. Scattered at a rate of 10-30 pounds per 1,000 square feet, it provides a 9% nitrogen source that is released slowly into the soil. After application, be sure to water it in well and then allow it to dry to remove the moisture from the crabgrass seeds. Because of the drying time that is required, corn gluten meal may not work well in areas that have excessive rainfall or have had a very wet spring.
Vinegar, or specifically the acetic acid in it, at more than 6% concentration. Most household vinegar is too low in concentration at 5%, but housecleaning vinegar is closer to 6% concentration. You can also increase the concentration by freeze distillation, basically putting the vinegar in a shallow plastic dish in the freezer, then removing ice crystals using a slotted spoon or skimmer. Because ice forms as a purer water, it removes the extra water from the solution. You should remove anywhere from 10-25% of the water content to create a solution strong enough to act as a crab grass killer.
Emergence
Depending upon the specific type, these herbicides work before, during and after a weed emerges. A pre-emergence herbicide should be applied a week or two before any weeds are seen. An emergence herbicide should be applied just as the weed begins coming out of the soil, and a post emergence herbicide is designed to kill a weed after it is already growing. All weed killers fall into one of these categories.
Persistence
Persistence essentially means how long weeds will be killed after a herbicide application. Non-persistent weed killers will not last longer than the day after application. On the other hand, persistent types can be made to kill weeds for extended periods after the initial application. If you want an area to be free of weeds for any length of time (such as pathways) a persistent weed killer would work best for this type of application.
Chemical Substances
Chemical herbicides run the gamut of characteristics. They can be contact killers, emergence killers, some manufactured for a specific weed type meaning they are highly selective, and some will have a persistence factor lasting years. They are also inexpensive to use, but caution must be taken around waterways, ponds and rivers as they are highly polluting and will kill off desirable water vegetation and the surrounding aquatic wildlife.
The newest herbicides are made from natural or organic substances like citric acid, garlic, clove oil and vinegar. Generally, they are of the contact variety and they are completely non-selective, meaning that they will kill any plant they touch. However, these are the safest herbicides available today, and many can be used around kids and pets without harm.
Pre-Mix Liquids
Pre-mix liquids are also popular for farmers. In this case, they are mostly used as pre-emergence types or selective weed killers during the growing season. Tanks of herbicide chemicals are mixed with water, than distributed by mechanical means while pulled behind a tractor.
Pathways
A contact spray can be used for growing weeds, but for long lasting weed killing, use a pre-emergent granular. You can lay on a pre-emergent granular before you mulch the path, and if you mulch yearly, also lay down some pre-emergent granular each time. A highly persistent type would be perfect if you are constructing a pathway. You could broadcast it beneath the first layer of mulch, and you would not have to worry about sprouting weeds for years.
Southern crabgrass (Digitaria ciliaris) is an annual invading species of grass. Also known by the names summer grass, tropical crabgrass and topical finger-grass, this hardy weed grows in areas where grass is wanted, but often grows out of control, robbing nutrients from the desired grasses and turf.
Native to the United States, crabgrass grows mainly in the warmer areas in the southern states. South and Central America, Mexico, Asia and the West Indies are also home to this variety of crabgrass, although it can probably be found just about anywhere on the planet. Any place that has a temperate climate can be home to this invasive weed.
Southern crabgrass is a big problem in crops that grow in rows, pastures, fields and gardens. It also invades prairies and waste areas, and grows freely along the side of the road. Unless you use a cloth or plastic barrier, there is no way to control the spread of southern crabgrass.
Picking and hoeing the weeds by hand is the best way to remove the plants. When they grow in crops or gardens, weed patrol must be done constantly. There are many chemicals that will kill southern crabgrass. However, the use of chemicals should not be used unless the weed has overtaken a valuable crop.
Stumble
Nothing can be more upsetting to homeowners than the sight of weeds in their lawns. Invasive and destructive, weeds cause immense frustration. This arises from the detriment they cause to lawns and gardens.
