Broadleaf weeds are a common problem in many lawns, competing with desirable grasses and plants for water, nutrients, and light. These weeds can be particularly troublesome, as they can spread quickly and be difficult to eradicate. However, there are several effective broadleaf weed killer solutions available to help homeowners and lawn care professionals maintain a healthy and weed-free lawn. In this article, we will explore the different types of broadleaf weed killers, their active ingredients, and how to use them effectively.
Types of Broadleaf Weed Killers
There are several types of broadleaf weed killers available, including selective herbicides, non-selective herbicides, and organic herbicides. Selective herbicides are designed to target specific types of broadleaf weeds, while leaving desirable plants unharmed. Non-selective herbicides, on the other hand, will kill all plants, including grasses and other desirable vegetation. Organic herbicides are made from natural ingredients and are a popular choice for homeowners who prefer a more environmentally friendly approach to weed control.
Selective Herbicides
Selective herbicides are the most commonly used type of broadleaf weed killer. They contain active ingredients such as 2,4-D, dicamba, and meclorprop, which are designed to target specific types of broadleaf weeds. These herbicides are usually applied as a spray or granule and can be used on lawns, gardens, and other areas where broadleaf weeds are a problem. Some popular selective herbicides include Roundup, Weed-B-Gone, and Ortho Weed-B-Gone.
Non-Selective Herbicides
Non-selective herbicides are designed to kill all plants, including grasses and other desirable vegetation. They contain active ingredients such as glyphosate and glufosinate, which are powerful enough to kill even the toughest weeds. Non-selective herbicides are usually applied as a spray and are often used to clear large areas of land or to prepare soil for new plantings. Some popular non-selective herbicides include Roundup and Finale.
Organic Herbicides
Organic herbicides are made from natural ingredients and are a popular choice for homeowners who prefer a more environmentally friendly approach to weed control. They contain active ingredients such as vinegar and soap, which are designed to target broadleaf weeds without harming desirable plants. Organic herbicides are usually applied as a spray and can be used on lawns, gardens, and other areas where broadleaf weeds are a problem. Some popular organic herbicides include Evolve and Nature’s Glory.
| Herbicide Type | Active Ingredient | Target Weeds |
|---|---|---|
| Selective Herbicide | 2,4-D | Dandelion, clover, plantain |
| Non-Selective Herbicide | Glyphosate | All plants, including grasses and desirable vegetation |
| Organic Herbicide | Vinegar | Broadleaf weeds, including dandelion and clover |
In addition to using broadleaf weed killers, there are several other ways to prevent and control broadleaf weeds in lawns. These include mowing regularly to prevent weeds from producing seeds, watering deeply but infrequently to encourage deep root growth, and fertilizing regularly to promote healthy grass growth. It's also important to maintain good soil health by adding organic matter and using compost to improve soil structure and fertility.
Prevention and Control Methods
Preventing broadleaf weeds from growing in the first place is often the most effective way to control them. This can be achieved by maintaining a healthy, dense lawn with good grass cover, as well as using physical barriers such as mulch or landscape fabric to prevent weeds from germinating. Regular monitoring and removal of weeds can also help to prevent them from spreading and becoming a problem.
Physical Barriers
Physical barriers such as mulch or landscape fabric can be used to prevent broadleaf weeds from germinating. These barriers work by blocking light and preventing weeds from growing. They can be applied to areas where broadleaf weeds are a problem, such as gardens and flower beds.
Monitoring and Removal
Regular monitoring and removal of broadleaf weeds can help to prevent them from spreading and becoming a problem. This can be achieved by regularly inspecting the lawn and garden for signs of weeds, and removing them by hand or with a tool before they have a chance to produce seeds.

Selective herbicides are designed to target specific types of broadleaf weeds, while leaving desirable plants unharmed. Non-selective herbicides, on the other hand, will kill all plants, including grasses and other desirable vegetation.
Are organic herbicides effective at controlling broadleaf weeds?
+
Yes, organic herbicides can be effective at controlling broadleaf weeds. They contain natural ingredients such as vinegar and soap, which are designed to target broadleaf weeds without harming desirable plants. However, they may not be as effective as chemical herbicides and may require repeated applications.
