Will Weed Killer Kill Flowers?

will weed killer kill flowers

Weed killers are designed to kill plants, so it stands to reason that they would also kill flowers. However, not all weed killers are created equal. Some are more targeted in their kill, while others are non-selective, so they kill any plant they come in contact with, flowers included.

Part of the spring and fall clean-ups we offer at JC’s Landscaping include planting seasonal flowers. Contact us today to get on our schedule.

There are two main types of weed killers: selective and non-selective.

Selective Weed Killer

Selective weed killers are herbicides that kill specific weeds without harming the plants around them. They accomplish this by targeting the weed’s unique metabolism, causing them to die quickly. This herbicide is often used in gardens and lawns, where it is important to target specific weeds without damaging the surrounding vegetation.

Most selective weed killers contain one or more of the following herbicides: 2,4-D, dicamba, or triclopyr.

2,4-D is a broadleaf herbicide that kills dandelions, clover, and other common lawn weeds. It’s also relatively safe to use around grasses, so you don’t have to worry about accidentally killing your lawn.

Dicamba is another common broadleaf herbicide that controls everything from annual weeds to trees and shrubs. It’s a bit more toxic than 2,4-D, so take care when using it around desirable plants.

Triclopyr is a broadleaf and woody plant herbicide often used in forestry applications. It’s effective at killing tough weeds like Poison Ivy and Kudzu.

Thinking of adding some plants and flowers to your outdoor space? Or interested in installing stone flower beds to house your plants and flowers? Consider hiring JC’s Landscaping for any landscaping needs you may have in Frisco, Texas.

Non-Selective Weed Killer

Non-selective weed killers are herbicides that kill any plant they come in contact with, including flowers. These herbicides work by causing cell death in the plant, resulting in a quick and complete kill.

Glyphosate is the most common type of non-selective herbicide. It’s often used in agriculture and for commercial weed control.

Glyphosate is a broad-spectrum herbicide, meaning it will kill most plants. It’s also very effective at killing weeds that have developed herbicide resistance.

Organic Weed Killers

Organic weed killers are a great alternative to traditional herbicides for those who want to avoid using synthetic chemicals. These products typically use vinegar, salt, soap, or lemon juice as their active ingredient.

These products typically don’t work as well as chemical weed killers, but they are safe to use around flowers and other plants.

Synthetic Weed Killers

While organic weed killers are a great option for those who avoid using chemicals, synthetic weed killers offer the best results for most weeds. These products typically contain one or more of the following herbicides: glyphosate, 2,4-D, dicamba, or triclopyr.

What Is Spray Drift or Overspray?

Bindweeds are commonly found in flower beds.

Spray drift occurs when herbicide particles travel through the air and land on nearby plants, causing them to become damaged or killed. This often happens when herbicides are applied in windy conditions.

Overspray occurs when herbicide particles land on areas you didn’t intend to treat. This happens if you don’t have the proper equipment to apply the herbicide or if you don’t follow the directions on the label.

To avoid spray drift and overspray, always follow the herbicide label’s directions and apply the herbicide on calm days with little wind.

You should also ensure you have the proper equipment to apply the herbicide, such as a pump sprayer or hose-end sprayer.

Cover Weed With Milk Jug Trick

If you don’t want to use herbicides or are worried about harming your flowers, you can try the milk jug trick. This involves placing a milk jug with the top cut off over the weed while you spray it with herbicides. 

This method will protect any surrounding plants or flowers from overspray. 

Ways To Prevent Weeds in Flower Beds

The best way to control weeds is to prevent them from growing in the first place. Here are a few tips to help you keep your flower beds weed-free:

  • Pull weeds regularly. The sooner you pull a weed, the easier it will be. Weeds compete with your flowers for resources, so the more weeds you have, the harder it is for your flowers to thrive.
  • Apply mulch. Mulch helps to prevent weed seeds from germinating by blocking sunlight. It also helps to retain moisture in the soil, so your flowers don’t have to compete with weeds for water.
  • Choose the right plants. Some plants are more susceptible to weeds than others. If you’re worried about weeds, choose plants known to be resistant to weeds.
  • Use a pre-emergent herbicide. Pre-emergent herbicides prevent weed seeds from germinating. They’re applied before weeds start to grow, so they’re a great way to prevent weeds from taking over your flower bed.

Wrapping Up

Weeds can be a nuisance in any garden, but they’re especially troublesome in flower beds, where they can compete with your flowers for resources. Weeding can be tedious, but it’s important to keep on top of it if you want to have a beautiful, weed-free flower bed. Consider using selective herbicides or the milk jug trick to kill weeds without harming your flowers.
