What Is Crabgrass and Why It Invades Your Lawn
Crabgrass is a weed that is an annual grass and grows in hot weather and in poor lawn condition. It is low to the ground and spread in a crab-like manner in a circle which is how it acquired its name. In comparison to healthy turfgrass, crabgrass is lighter in green hue and rough in texture and becomes evident when it starts spreading.
What makes crabgrass such an unwelcome guest in lawns is this simple, it seeks opportunity. The crabgrass seeds take advantage of any opportunity that arises whenever your lawn is thin, weak and damaged. Half-baked areas, soil compaction, mowing and irratic watering all provide it with the optimal conditions to flourish.
The problem with crabgrass is that it a single season can yield thousands or more seeds and is hard to control. You may take out the visible plants, but the seeds that have retained themselves may lead to a new infestation come the next year.
Why Crabgrass Keeps Coming Back Every Year
The way to really know how to get rid of crabgrass in lawns is by knowing the lifecycle of crab grass. Crabgrass is not a weed that is a perennial plant but one that has a life cycle of one year but its seeds guarantee its reappearance.
Crabgrass seeds germinate in early spring at a temperature of between 55 o C or 13 o C. The plant spreads rapidly all over the weaker sections of your lawn as the temperatures rise, and it spreads throughout the summer. It dies with the first frost by the end of the summer and early fall bearing seeds.
The plant itself perishes but the seeds will be lying in the ground, waiting to spring up in the following spring. It is this cycle that is repeating hence the reason why many homeowners are feeling like they are engaged in a never ending war.
How to Get Rid of Crabgrass in Lawn Step by Step
Crabgrass can only be removed with preventive and immediate processes. To do it right would be to not only deal with the already existing, but also with the seeds, which are yet to sprout.
Identify Crabgrass Early Before It Spreads
You can control crabgrass easier when it is detected at the earlier stages. It is much easier to remove and treat the young crabgrass plants than mature plants are. Initially it grows as tiny, light green stems which spread instead of growing straight up just like normal grass.
When you notice these early symptoms, you can take measures before the plant grows and gets seeds, and then it is vital to have control in the long run.
Remove Crabgrass Manually for Small Infestations
When there are small patches of some areas in your lawn, then manual removal can be highly effective. Pulling crabgrass must be done when the ground is wet because it is then more likely to remove the entire root system.
The pull of the plant should be done with care taking into consideration the roots. When any of them is not removed, then it can further develop. The approach is particularly effective among house owners in need of advice on how to get rid of crabgrass in my lawn without applying chemicals.
Use Post-Emergent Herbicides for Active Growth
In cases where crabgrass has already taken root over bigger surfaces, then it may not be feasible to remove them manually. In the instances where this happens, post-emergent herbicides have to be used. These are products that are aimed at killing crabgrass once it has germinated.
To achieve a maximum effect, plants in their younger and actively growing stage should be sprayed with herbicides. Grown crabgrass is highly resistant and might take up treatment several times. When using herbicides, it is also crucial to take care so that nearby grass is not ruined, particularly during hot seasons.
Apply Pre-Emergent Herbicides for Prevention
In the case of crabgrass, prevention is the best approach. The pre-emergent herbicides- These are used to prevent germination of crabgrass seeds.
Timing is everything. The products need to be used at the beginning of the spring before the soil acquires a temperature that would allow seed germination to occur. Early or late application will diminish effectiveness.

Spring Is the Most Critical Time
