Weed Killer Chemicals to Avoid?

The way you apply your weed killers can make a huge difference in keeping flowers, trees and shrubs safe from lawn weed treatments. One way is to avoid windy days.

However, there are some chemicals to avoid as well as. Active ingredients like glyphosate can be particularly harmful when they come into contact with trees and flowers as you apply it to your lawn.

You can go as far as finding any products to kill weeds, being organic or chemical, they can all pose problems, flowers and trees if they are affected by spray drift. If granular, spreaders can toss these further than you expect and cause problems that way.

Proper Techniques

You will need to avoid weed treatments contacting your landscape trees and shrubs. It is best to resort to hand pulling weeds that are in the first few inches close tom your trees or flowers.

You should also follow directions exactly as to not over-spray or over-treat your lawn. Doing this can lead to issues of wind drift or runoff.

One thing gardeners overlook is the mixing of gardening tools that are used in lawn care and with weed killers. You need to control the use of nozzles and watering cans when used for weed killer application and those that are for watering flower beds.

When applying weed killer, it is good practice to cover flower beds and bases of trees with a large plastic sheet as you spray. When you cover these areas, it can stop the harm of your plants and trees, yet you do need to take care.

Spray on calm days when there is a little breeze can be vital for avoiding weed treatments drifting onto your flowers and trees.

Postemergent Herbicides

Many pre-emergent weed killers products, or ones, which prevent weed and grass seeds from germinating. These products are mainly granules that you may spread and mix into the soil around the base of your tree or shrub.

The way this work is to prevent seedlings from germinating and taking hold. It is worth noting; they aren’t effective against grass which uses rhizomes to creep and take over areas.

On the other side, post-emergent herbicides, often appear in spray form, and because of this, you can dose large areas beneath a tree or target single weeds with the solution.

The way this work is to be absorbed through the leaves and kill the plant from the inside out.

Be sure to read labels and apply at the recommended doses. You can find some of these herbicides will affect woody plants when applied in high doses.

Because of the narrow target area, you can use these on weeds in your flower bed, in between your desirable plants without and preventing too much harm from contact.

Be sure to always read the label as a windy day can still blow these to your desirable plants accidentally. (Find out How Long Does it Take a Tree to Grow)

Choosing the Right Weed Killer

When you have mature trees, these have thick bark that can protect them from a range of post-emergent herbicides. However, be sure to pick the right herbicide so it won’t soak through the soil to the tree or shrub roots.

If you have a pre-emergent herbicide where the main active ingredient is glyphosate, mature trees should be strong enough to fend this off. The chemical won’t leach through the soil and reach your tree’s roots.

Sethoxydim is another active compound and also rated as safe to spray around trees and shrubs.

Stopping Re-Growth

One of the main issues is weeds returning, so rather than keep tackling these using weed killer all the time, you can take precautionary steps to stop weeds coming back.

Well-designed shrubs and building

Using a good 4-inch layer of mulch can work in the same way as a pre-emergent and can get rid of weeds and stop them coming back. It may not rule them out 100% from germinating, yet it will make hand pulling much easier should they spring up. (Learn How to Remove Chickweed in Lawn)

One thing to make this mulch weed killer more effective is to use a weed control barrier. Even more, this can be a great product to add weed prevention around your desirable plants and trees when under your mulch.

Using these methods, you also protect the root of your trees and any related shrubs as you are free from using chemicals on your landscape.

If you need to use a weed killer product like herbicide, it is best to opt for one of the popular organic herbicide varieties as they won’t affect the environment half as much as chemicals will.

Another effective application is to take boiling hot water and pour this onto the leaves of the weeds. It will start killing them instantly, and won’t affect the root of your trees or shrubs.

This method isn’t permanent, yet your weed killing is free from any chemical spray use around your plants or grass in your garden.
