Identify the Broadleaf Weeds

The first step in controlling broadleaf weeds in turf is to properly identify them. Identification is important because in many cases there is a preferred herbicide that has better activity against a particular weed. Because broadleaf weeds look similar to other species.

Manufacturer

You should check out top-rated and popular manufacturers who have specialized in making pesticides and fertilizers. They have had a good experience in delivering high-quality pesticides for years. You can check out reviews about the manufacturers to have an idea about their products.

Composition

Beware of the ingredients used in a broadleaf herbicide as some of them are dangerous and can be hazardous to your pets, humans as well as the environment. Avoid buying a product that contains more amount of glyphosate as it is an active ingredient that might harm the environment. Instead opt for those weed killers which contain organic composition as they are safer to use on your lawns and low risk to birds, bees, and aquatic life.

Weed Type

Do you want to control one single weed or many weeds from your garden? It totally depends upon you but before making any final decision about purchasing a broadleaf weed killer make sure that the ingredients are capable of controlling the weed you are planning to eliminate. Some chemicals can also control dandelions, clovers, and other broadleaves simultaneously.

Application

Application is an important part of buying a good quality broadleaf weed killer. Usually, these pesticides use with a sprayer or spreader. So, that they become easier for home users to apply them to any desired location without making any mess. If possible go for those products which have a long shelf life so even if you don’t plan to use them frequently. There should be no chance of chemical degradation after opening the container.

Post-emergent Broadleaf Weed Control

In most cases, the best control strategy for perennial broadleaf weeds is to apply post-emergence broadleaf herbicides in the fall. When air temperatures are in the 40s and 50s and soil temperatures are in the 50s and 60s.

There are several advantages to this but the most significant is that the herbicide is more likely to translocate throughout the root system. Resulting in complete control with springtime applications.

It is more common to see temporary suppression of the top growth. With regrowth of the weed occurring within about 60 to 90 days.

Another benefit of fall time applications is that landscape plants are less likely to be injured. Most of the herbicides that we use to control broadleaf weeds and turf are quite phytotoxic to ornamental plants particularly if applied in the spring when the plant is leafing out a properly timed.

When controlling perennial broadleaf weeds in the fall it is very important to choose the right formulation of the herbicide.

Durability

Most broadleaf herbicides are designed in such a way that they provide quick results within hours or days only but no one guarantees their long-term control. So make sure to buy a product that controls the weed for at least 2 months with less or no effort.

Price

Price is another factor that comes into play while purchasing a broadleaf herbicide as it varies from one product to another depending upon its composition and effectiveness. Go for those products which can be easily afforded by your budget and provide good results within a reasonable price range.

Precautions

Most manufacturers provide precautions with their products but still, you should consider taking care of a few things like keeping all pets and humans away from the treated lawns, avoiding contact with soil and plant materials after spray application, and keeping children off sprayed areas until the chemical completely dries up on the grass.

Mow Your Lawn

Mow your lawn for a proper height range. In summer, keep your lawn at the higher end of the range to prevent burnout. This helps the grass to remain stronger and more likely to choke out the broadleaf weeds.

Tips and Warning

Choose the herbicide that is specially formulated to kill broadleaf weeds in lawns and gardens. The best time to apply the herbicide is when broadleaf weeds are actively growing on a sunny day when no rain is expected within 24 hours.

Some hard to kill weeds require another application. See the product labels for the best time to apply the second application.

Make sure do not to apply other products to kill broadleaf weeds that are not specified to kill such weeds.
