Best Crabgrass Preventer Buying Guide 2021
Nobody can win any battle without knowing his competitor. For that reason, before rushing into buying a random herbicide on the market, it is necessary to prepare some basic biological knowledge, at least the life cycle of the crabgrass.
Thence, you will know that there are two common types of crabgrass killers: Pre-emergent and Post-emergent herbicides. Each type of herbicide contains different substances to kill the grass from the root based on its cycle characteristics.
Besides, you might also need to consider other factors depending on what you want to do with the lawn overall.
What Would You Prefer: Selective Or Non-selective?
All herbicides can be either selective or non-selective types. Selective herbicide does not eliminate all kinds of weed. but only works on some specific kinds, such as broadleaf or grassy weeds. In doing so, it cannot harm non-targeted plants, which makes it highly beneficial while spraying the product on lawns.
However, as it only works with a particular type of grass for a product, you need to read the product label carefully. Or else, your crabgrass elimination plan might not take effect pretty well. The instructions also inform you about the area recommended for the products. So try to keep it carefully in mind!
On the other hand, the non-selective herbicide is quite a kill-it-all type. It will give you a complete plant-free finish, leaving a brand new soil area for you to grow new weeds. Therefore, it is advisable to use it for driveways cracks. If you are planning on a landscape makeover or flower bed replacement, it will work excellently as well.
Pay Close Attention To The Application Method
While shopping for herbicides, you would notice that they come in either dry granules or liquid sprays. Mostly praised for high productivity in large areas, the liquid sprays work wonderfully with a hose-end sprayer.
You can eliminate all the crabgrass in the garden within less than an hour. It is highly recommended to use a tank sprayer to better mobility and control over crabgrass regarding smaller areas and spot treatment.
But there is a caution: Watch out for the wind direction to prevent spraying in unwanted areas. It might harm other weeds.
And there comes a second type; the dry granules are mostly for pre-emergence or post-emergence herbicides. They usually go with a calibrated lawn spreader to complete their crabgrass removal. After the work is done, you should store it in cool, dry conditions for next use.
The downside of this herbicide is that it takes you more time to spray all over the lawn. And it might not work if the grass has already grown. So it is critical to pay attention to those features to get the best choice.
Now let’s check out some answers to FAQs from customers we often receive! It can help you considerably in sorting out the final choice.
When Should It Be Best To Start Using Crabgrass Preventer?
It is ideal for applying the product in summer when soil temperatures are above 55 degrees Fahrenheit constantly for three days, they gradually germinate as crabgrass seeds grow fast when the weather warms up.
The process will go much faster when the temperature range is around 60 and 70 degrees Fahrenheit. Therefore, you should take control of the growth of crabgrass from this stage. When it reaches late summer, it might require a much stronger solution.
What Do I Use To Kill Crabgrass Only?
Once the weed grows and crabgrass no longer in its germination stage, your healthy lawn is under great threat. Pre-emergents can not work anymore. You would need to apply stronger crabgrass control which is selective and post-emergent herbicides. These special formula products will return your favorite garden to the beautiful, untouched stage.
Will Heavy Rain Wash Out Pre-emergents?
It is the most common misconception when gardening. Not only does the rain not wash away the beneficial chemical, but it also pushes the product further down the soil. Thus, you can better prevent those annoying seeds from developing into mature crabgrass.
Even if you live in rainy Seattle, it is completely suitable to take such precautions to protect the plants.
What Would I Rather Do: Kill Weeds Or Overseed First?
To grow a healthy lawn, killing weeds first is a must. Any weeds would slow down or even harm the growth of your plant in the future. If identified soon, you should deal with the weeds to create the most favorable environment for new plants to grow.
It is advisable to spray lawn weed killer two weeks before you start to germinate your plant. The soil would absorb the chemical enough to kill all the grass and restore its nutrition balance to start a new growth plan.
Should I Pull Out Crabgrass?
Most crabgrass will die when fall arrives, after the first frost. However, you should make sure to remove all grass seeds as they disperse through the wind. Or else, there is a high chance that they will come back next season. So the best way is to remove all the weedy clumps you can see.
You can use pre-emergence or pull it out by hand. But if you intend to do the chemical-free method, it is better to use extra props such as sod cutters.
