Whether you’re looking to clear out a wide area of weeds, target smaller patches or prevent weeds from happening in the first place, you can find the best brands of weed spray and lawn weed killer like Roundup, Preen and Ortho at Ace. Keep reading to learn about different weeds and the types of weed preventers and killers available.

Common Types of Weeds

A weed is a plant that can cause ecological damage to existing native plants or even to animals and people in the area. Some of the most prevalent weeds include:

  • Broadleaf weeds, which are leafy and often have flowers.
  • Grassy weeds that look and act like grass.
  • Grass-like weeds, which are similar to grassy weeds but have solid stems instead of hollow ones.

Broadleaf, grassy and grass-like weeds are further categorized by their life cycles. Each of these categories can feature annual, biennial or perennial weeds. Annual weeds complete their life cycles in one year and biennials in two years, but perennials can survive much longer. Learn more about the most common types of weeds and how to tackle them.

Crabgrass

Crabgrass is an annual weed that mainly grows in the summer when the ground is warm. It will die naturally as soon as the ground frosts. Since crabgrass can spread quickly, you can nip the overgrowth in the bud with a non-selective weed solution that is specifically formulated as a grass killer.

Using a weed preventer for crabgrass is also important because crabgrass seeds can stay healthy and create new weeds for up to three years.

Pigweed

Another annual summer weed, pigweed is a bit leafier than crabgrass and has a red taproot. This problematic weed should be pulled before it flowers to prevent spreading.

Dandelion

Abundant in spring, dandelions are perennials that are known by their bright yellow flowers. After they flower, their seeds are spread through the wind. Dandelion roots are large, which means if you don’t pull dandelions out by their whole root they will pop back up again.

Chickweed

This weed is an annual that grows best in the winter in very moist areas. It’s a great habitat for insect pests as well. It grows about two inches high and has small white flowers, and if left to its own devices, chickweed can limit your garden harvest.

Types of Weed Killers

Depending on the type of weed you’re targeting, there are several different types of weed killers available for you to choose from.

Spray Herbicides

Spray herbicides are liquid solutions that can be sprayed for contact, which means you can directly target unsightly weeds wherever they grow. From flower beds and vegetable gardens, to the cracks in driveways, walkways and patios.

Contact weed killers come mixed. Concentrates that may need to connect to your hose for use are non-selective, meaning they are harder to contain when spraying.

Weed Burners

To avoid destroying the plants you do want and potentially exposing children and pets to strong ingredients, weed burners, or torches, eliminate weeds by flame. However, you should not burn weeds in extremely dry areas to help prevent the spread of wildfire.  

Granules

Weed preventer and killer granules can be applied using a spreader, making them great for conveniently  wiping out large sections of weeds and vegetation. They’re ideal for spreading on walkways, along fences and under decks.

Vinegar and Nontoxic Weed Solutions

Most nontoxic weed solutions are made with a vinegar formula. They usually come in sprays that use the organic acid of vinegar to start killing plants promptly in soil.

What’s great about these ecofriendly, biodegradable weed killers is they don’t contain any chemicals that could harm your garden crops, pets or family.
