What Are Weeds?

Pic 1 thistle
Weeds come in all shapes and sizes, and there are hundreds of different species.

Weeds, by definition, are any type of plant that is unwelcome in your yard or garden that causes economic or ecological damage or loss to crops, gardens, yards, animals or people.

There are three different kinds of weeds:

Troublesome Weeds

Troublesome weeds are plants that are undesirable to the common public either because they are unsightly, unwelcome, were not planted, or that cause damage or ecological loss to yards, gardens, animals or people.

Noxious Weeds

Noxious weeds are plants specifically labeled by government officials as damaging or dangerous to agriculture, public health, wildlife, property and recreational areas.

Invasive Weeds:

Invasive weeds are plants that grow in areas where they are not native. These weeds have likely spread through human transportation, animal transportation, or other unnatural means.

Because these weeds are not common to the region they are growing, they are often more difficult to control as they have little to no natural adversaries in the region. Invasive weeds are especially dangerous to the local ecosystem and native plants for this reason.

While all types of weeds are bothersome, and while they are thought of primarily as undesirable plant life, it’s important to remember that they do play their role in a healthy ecosystem. Not all weeds are bad, and in fact, some people even find certain species of weeds appealing.

We should also note that there are upwards of 250,000 species of plant species throughout the world, and weeds (or what we would consider weeds) make up only about 3%.

Many weeds also have their benefits. Some contribute to a healthy yard and garden by stabilizing the soil, while others provide a safe habitat and food source to beneficial wildlife. Some weeds are even edible to people, providing us with delightful teas, salads, and even wines.

Regardless of where you stand on weeds or what you classify as a weed at all, it’s important to understand that even the best weed killer for lawns is only going to work if you have done a bit of research and understand your lawn and the types of weeds you are dealing with.

If you’re anxious about using the best weed killer for lawns, you do have other options. There are plenty of home remedies and tactics you can use to control and remove weeds on your property.

Remove Weeds By Hand

This may be easier said than done, especially if your lawn is overgrown with problematic weeds. However, while time consuming, it is possible to get rid of weeds by removing them physically.

Just make sure you remove the entire root, otherwise the weeds will continue to grow and cause issues in your yard.

Make Your Own DIY Weed Killer

Ingredients:

  • 1 Cup of Salt
  • 1 Gallon of White Vinegar
  • 1 Tablespoon of Liquid Dish Soap
  • 1 Large Container (For Mixing)
  • 1 Spray Bottle (For Application)

Directions:

Combine the above ingredients in a large container and mix it well to create the best weed killer for lawns that is natural and safe, then pour what you can into a spray bottle. Apply this concoction to the problematic weeds in your yard in the morning or just before noon, when the sun is out and shining. This will help the mixture set.

While this vinegar mixture is a safer alternative to using chemical herbicides in your yard, it can still cause damage to ornamental plants and lawns. Use this method carefully and avoid spraying it on any plant you do not wish to harm.

Newspaper

You can also use newspaper as one of the best weed killer for lawns methods. This is a natural and safe way to protect your yard and garden from problematic plants without using chemicals or sprays.

It is also one of the easiest ways to get rid of a large expanse of weeds at once time. Simply place newspaper over sprouted weeds, soak the newspaper with water, then cover it with mulch. This will suffocate the weeds and prevent sunlight from reaching them, thus killing them within a few days.

Corn Gluten Meal

Using corn gluten meal as the best weed killer for lawns is effective, but only if you use it before weeds have sprouted. Corn gluten meal stops weeds from germinating, so use it before you see weeds by spreading it throughout your lawn and around already-established plants.

Shower Curtains

Just as with newspaper, a layer of shower curtains covered in mulch over weeds will prevent weeds from getting sunlight and water. This will kill the problematic plants within a few days.

DIY Vodka Weed Killer

If you don’t have vinegar on hand but you do have vodka, you can use this world-famous beverage to knock weeds out cold.

Ingredients:

  • 1 Ounce of Vodka
  • 2 Cups of Water
  • 3 Drops of Liquid Dish Soap
  • 1 Spray Bottle

Directions:

Combine the above ingredients in a spray bottle and spray it generously over the weeds in your yard.

This vodka concoction is the best weed killer for lawns when it comes to weeds that thrive in sunlight. It will dry the weeds up and kill them quickly. Of course, like the vinegar mixture, this vodka weed killer can be harmful to ornamental plants and yards, so be careful when applying it.

Boiling Water

If you’re looking for the easiest, and  inexpensive best weed killer for lawns, then look no further than boiling water. Just boil water in a kettle or pan and (very carefully) pour it over the weeds in your yard.

Remember, while boiling water is one of the best weed killer for lawns options, it will also kill any other vegetation it is poured over. So use this method with caution.

Tips On Preventing A Future Weeds In your Yard

All lawns are riddled with weed seeds beneath the soil, but there are ways to prevent these seeds from sprouting. 

Weed control is an important part of growing a healthy lawn or garden, and the best way to control weeds is to stop them before they begin. This can be difficult, considering that your entire yard contains weed seeds.

But don’t worry – this means your yard is healthy. Furthermore, you can work to keep weeds from germinating by following the below tips and tricks:

Avoid Unnecessary Disturbance of Soil 

Most weeds can only grow when they have enough access to sunlight. While your entire yard is riddled with weed seeds, the only weeds that grow are the ones that reach the surface. To avoid germinating weed seeds, avoid unnecessarily disturbing the soil.

When you are gardening or even removing weeds, use small tools like knives or screw drivers as opposed to gardening shovels. Also make sure to only dig or remove weeds when necessary.

You may also consider using these sharp-bladed tools to leave the weed in place, but slice through the root of the weed to kill it.

Use Mulch

Weeds will crop up in areas where other plants or lawn grass is not particularly flourishing. Of course, in some cases, weeds will crop up anyway and compete with these plants. Still, in areas you wish to keep free of vegetation, use mulch. Mulch helps keep your landscaping looking lovely while also prohibiting sunlight to soil, thus reducing the chances of weeds.

You can also use mulch to fill in the gaps between plants in gardens and along borders of your lawn. This will serve the same purpose.

Avoid Watering Weeds

This can be tough, especially if weeds have cropped up closely alongside other plants and in lawn grass. However, try your best to avoid watering these weeds and instead provide water only to the plants and lawn area you want to cultivate.

Use A Trusted Pre-Emergent 

Pre-emergents stop germination of weeds before they sprout. A pre-emergent does not kill weeds or harm plants that have already sprouted, so this is a great way to prevent weeds without harming your lawn or already established plants.

That said, like using the best weed killer for lawns for weeds that have already grown, using a pre-emergent has its pros and cons. There are also natural and chemical pre-emergent products available, as well as some pre-emergent chemicals that are banned in some regions.

Make sure you do your research and know what you can and cannot use when it comes to weed control in your yard and around your home.

We hope this has been a helpful guide on the best weed killer for lawns. Remember to take your time, do your research, and use these products only as directed. Best of luck and happy landscaping!
