How to Identify Broadleaf Weeds?
Broadleaf weed is not difficult to identify as soon as you understand their main characteristics.
Most weeds have flat leaves and web-like veins, others have showy flowers – however, you can easily spot them since they don’t fit in.
There are different types of broadleaf weeds that need to be treated separately for successful elimination.
- Annual broadleaf weeds grow from seed, they flower, grow more seeds and then die every year. Moreover, some grow in spring and die as soon as winter comes and others sprout in fall and die before summer starts.
- Perennial broadleaf weeds can live more than 2 years and unlike annuals, they don’t sprout from seeds but from bulbs, tubers, rhizomes and stolons. These are the most difficult to manage and destroy because they spread very fast.
One of the most recognizable weeds is dandelions. They’re perennials that sprout in springtime; they grow yellow flowers that turn into the puffy seeds which are spread all over your lawn as soon as the wind blows.
When to Apply a Broadleaf Weed Killer?
The answer to this question depends on the type of weed you need to eliminate and whether you’re treating it pre or post-emergence.
As the name implies this strategy is based on prevention of weed growth. That’s why you need to use an appropriate, pre-emergence product and understand the type of weed you’re dealing with.
Annual weeds are best controlled with this type of herbicide because you know their growing pattern and as far as perennials go you need to understand how they grow and then apply the product.
Ideally, the weed killer should be applied before they start to germinate. If you’ve already seen the weeds on your lawn don’t waste your time and money in applying a pre-emergent weed killer since it’s not going to work.
When it comes to this type of treatment, you can work on destroying already existing broadleaf weeds. In this case, you need to apply the product during active growth and make sure you identify the exact weed type in order to deal with it effectively.
This weed killer should be applied in the first months of spring and fall i.e. when the grass is most active.
As we mentioned in some of our product reviews, make sure you apply the product in cool weather since hot and drought conditions dry out the surrounding grass and make it susceptible to damage.
How to Apply Broadleaf Weed Killer?
The application of the broadleaf herbicide depends on the type of product you are using i.e. whether it’s granular or liquid. Below, you can review both options.
If you require a broad application, then a granular weed killer can do the job and help you cover the entire area such as your lawn or pasture.
When applying make sure you have all the necessary equipment such as a spreader that can be hand-held if you’re dealing with a small area or a bigger, commercial one for your larger affected areas.
As soon as you apply the weed killer granules, make sure you add plenty of water in order to activate the product. You can irrigate with a simple hose or a sprinkler system and if planned properly rain might come in handy as well.
When it comes to liquid weed killers, you have to be more careful and precise when applying. There are 2 variants available – a liquid concentrate or ready to use spray.
- The liquid concentrate requires mixing with water and then applying with a sprayer. For best results, make sure you follow the manufacturer’s instructions and get info on the exact water to concentrate ratio. This depends on the type of weed and location.
- The ready to use spray is a more convenient option which usually comes with a nozzle bottle to which you need to attach the hose and spray away.
The option you chose depends on the area the weed killer needs to be applied. If you need to cover a smaller area you can certainly use the ready to use spray since the hose length limits your movement and it’s not ideal for big lawns.
On the other hand, if you’re dealing with a larger area consider using a portable sprayer.
Why are Concentrates a Better Option?
Concentrates might be a better option since they’re stronger and can kill even the most persistent weeds in your garden.
Moreover, concentrates usually provide more value in terms of money, quantity and quality and most of the options we presented are affordable concentrates. Plus, their long shelf life allows you to use them for years if stored properly.
Whatever product you choose, make sure you follow the included instructions and understand how they work before you start applying. Protective equipment is a must so don’t compromise when it comes to this.
