How To Identify Types Of Weeds

Broadleaf Weed

Just like the name suggests, this type of weed has large and flat leaves. You can notice it quickly due to its appearance.

You will mostly come across some in this category like dandelion, clover, chickweed, ground ivy, etc.

Grass-like Weed

This weed is the most commonly misunderstood type since it has the same appearance as typical grasses. However, it usually has more hollow leaves in a tube or triangular shape.

The most common examples of this type are wild onion, wild garlic, and nutsedge.

Grassy Weed

You may confuse this type with regular grass due to its name. That is understandable because it only grows one leaf at a time. This type of weed includes foxtails, annual bluegrass, crabgrass, and quackgrass.

Some expert gardeners even divided weeds into 3 types based on their life cycle: annual, biennial, and perennial.

  • Annual weeds: Only produces seeds for 1 season.
  • Biennial weeds: Produces seeds in 2 consecutive seasons.
  • Perennial weeds: Produces seeds over a long period.

How To Get Rid Of A Lawn Full Of Weeds Naturally

Pull Weeds Out By Hand

If you don’t know how to get rid of weeds on the lawn, you can always use the old-fashioned way to get rid of them: pulling them out by hand.

Even if you already use other solutions with your lawn, you still need to pull out visible weeds by hand, sometimes manually.

Some common lawn weeds may sprout from any roots left in the ground; therefore, it’s essential to remove the root altogether.

To avoid accidentally distributing seeds elsewhere, you need to wear a particular pair of gardening gloves for the job.

Use A Core Aerator

If you don’t know how to get rid of weeds without killing grass, aerate your lawn.

Compacted soil is the greatest enemy of a healthy lawn. It will make your plants hard to get enough air, water, and nutrients through their roots.

It will also be an ideal environment for common weeds to grow. A core aerator will create thin holes across the ground surface to allow air circulation and help water to move more freely.

Cover Weeds With Mulch

Covering your planting areas with an extra layer of mulch can prevent new seeds from developing, as well as hold moisture to enhance your soil.

For weed seeds that are already underground, this layer will also keep the sunlight from reaching them. It will stop these seeds from sprouting into new weeds.

Cover Weeds With Newspaper

If you don’t have mulch available in your garden, you can use newspapers as an alternative.

By covering the planting areas with a thick layer of newspaper, you can block the sunlight from reaching the weed seeds underground and stop them from sprouting.

Before laying your newspaper down, you need to wet the soil thoroughly first. It is also a great way to recycle and attract earthworms to come into your garden.

Use White Vinegar

Most gardeners are aware that strong vinegar is one of the organic herbicides. You can either use white vinegar on its own or mix it with salt and dish soap for a better result.

The method is straightforward. All you have to do is fill a bottle with vinegar mixture and spray directly on the weeds you want to kill.

Since vinegar can be activated by heat and sunlight, you should do this on a sunny day. It will also ensure that the rain doesn’t wash the mixture away before it does the trick.

Pour Boiling Water

Pouring boiling water is the simplest way to scald those nasty weeds. To combat those unwanted weeds, boil a kettle of water and pour it over them.

However, for deep-rooted weeds, you might need to repeat the procedure several times to stop them from coming back. Make sure to wear long pants and proper footwear to avoid burning yourself.

Use Cornmeal

Did you know that corn gluten meal can stop seeds from reproducing? If you sprinkle cornmeal into your garden, it can prevent weed seeds from sprouting into plants.

These natural weed killers won’t harm your animal and can be found in most local groceries.

Burn Weeds With Flame

Burning weeds with flame is another natural way to kill weeds using heat. Passing a flame over weeds for a short period can kill the cells within them.

You don’t necessarily have to roast the weeds. Just by wilting them can quickly kill them.

However, this method can only work with the weeds above the soil surface, not deep roots. You will have to flame your weeds several times to ensure that they are entirely gone.

This is not the best way to kill weeds in dry weather due to fire risks. Always wear protective clothing and follow the instructions for safety purposes.

Use Sunlight

The sunlight or solarize method means covering the weed areas with plastic sheets and letting the sun do the rest. The heat from the direct sunlight will toast the garden weeds.

This process can take up to 4 to 6 weeks. When you see the weeds underneath become brown and withered, you’ll know that your issue is resolved.

Use Pre-emergent Herbicides Or Post-emergent Herbicides

Pre-emergent herbicides and post-emergent herbicides are the perfect options if you want to kill weeds in your lawn without harming your grass.

The best time to use herbicides is early spring or late fall. Around this time, the soil temperature is optimal for the task.

For large weeds areas, you will need to proceed with annual applications.

Use Weed And Feed Fertilizer

Weed and feed is another term of lawn chemicals that can kill weeds. This product will fertilize your soil and control existing weeds at the same time.

When you spread weed and feed on the ground, the weeds absorb the liquid and die slowly. In contrast to other chemical weed killers, weed and feed fertilizer won’t harm your plant or grass seed – unless you use too much.

The Most Useful Tips For Weed Control

Do Not Dig The Sleeping Weeds

It’s important to know that every square inch in your garden contains weed seeds. So digging the soil can bring them to the surface and increase weed growth.

Instead of digging into the soil, you can use a sharp knife to slice through the weed roots and break their feed source.

Since weed seeds can be dormant for a long time, minimizing soil disruption and limiting digging is better.

Water Your Plants Only, Not The Weeds

Some perennial weeds sprout rapidly in moist areas. That’s why you have to water only the plants that need it.

By depriving weeds of water, you can turn the drought to your advantage. You can use soaker hoses to avoid the growth of weeds in unplanted areas.
