Weed Killers Buying Guide for Garden

People should keep in mind weed type and location when choosing a weed killer for their garden or farm. They should note how products differ and pick the best option for them and their garden or lawn. Timing is also important for maximum effect. 

Sierra Natural Science recommends farmers to take into account these factors so that they can select the right type of weed killer:

Selectivity – what the herbicide does and doesn’t kill.

  • Selective – kills weeds and not adjacent plants, for instance in the lawn or garden.
  • Non-selective – kills all plants. Example of application: on a driveway.

Emergence – if the herbicide is inhibitory or not.

  • Pre-emergence – destroys plants and prevents them from sprouting.
  • Post-emergence – destroys mature or maturing plants.

Persistence – length of effectiveness after initial application.

  • Persistent – prevents regrowth for a while.
  • Non-persistent – doesn’t prevent regrowth.

Contact weed killers – kills the plant as it comes into contact with the product:

Systemic weed killers – controls the weed by pervading its roots and killing from the inside out. It’s effective but slow.

Residual weed killers – creates a barrier that keeps the weed from germinating and taking root.

Which Natural Weed Killer Works Best?

The gardening aisle may seem like the simpler and most practical options. But when a person is so inclined to make their own weed control product,  commonplace items can be found in a household. Here are some of the more popular homemade weed killer remedies:

  • DIY weed killer recipes
  • Newspaper
  • Boiling water
  • Lemon Juice

DIY Weed Killing Recipes for Garden or Lawn

A simple formula to use is to incorporate a cup of salt, a tablespoon of dishwashing liquid, and a gallon of vinegar. For this natural weed-killing recipe, one should mix it well and use a spray bottle to apply, toggling between aerosol and jet stream for maximum effect. For best results, one should apply it on a sunny day to the lawn or garden.


Yes! Yesterday’s headlines. Newspapers obstruct light and adequate air from reaching growing weeds and new seeds, preventing them from taking root in the garden or lawn. By adding subsequent layers of mulch on top of the paper, you keep the newspaper from being blown away by the wind, and increase the effectiveness of the newspaper.

Boiling Water 

It’s affordable, easy, very efficient, and organic. Works very well for weeds that take root in the cracks on sidewalks, driveways and walled hedges. Plus it’s an obviously environmentally friendly method of killing weeds without harsh chemicals.

Lemon Juice 

Lemon juice is a simple, inexpensive and readily available alternative. Lemon juice acts as a natural acid that burns and kills weeds. Users should put enough lemon juice in a spray can and apply on weeds. For an extra-strong combination, one should add acidic vinegar for an added punch.

Killing Weeds with Brains and Brawn

If weed control was so simple, Sierra Natural Science wouldn’t be in business in the first place. Taking care of weeds isn’t always as simple as buying the weed killer in the gardening aisle and spraying from a sprayer. It requires taking into account some considerations for a full multi-faceted approach to achieve the best and most sustainable results.

Here’re some technical weed killing strategies one needs to keep in mind:

  • Understanding the weed
  • Spraying versus pulling
  • Nipping the problem in the bud (preferably the root)
  • Timing
  • Tools

Understanding the Weed

To find the best technique to kill a specific weed in your garden or lawn, one has to figure out how it grows. When it develops, the best time to attack it, and the kind of weed – regular/yearly or enduring, are important considerations.

Spraying versus Pulling

Pulling weeds by hand from your garden or lawn is practical when one is managing a little territory or only a couple of weeds. Farmers should ensure they pull out the roots to prevent weeds from growing again in the garden. But for large farms, this method is time consuming, labor intensive and costly.

Nipping the Problem in the Bud (preferably the root)

Farmers and growers should not let weeds supplant themselves in their lawn or garden. One should use a pre-emergent herbicide such as “WeedRot Ready to Use Weed Killer” to keep weed seeds from growing on planting beds and yards.


One should attack weeds as early as possible in the growing season or cycle when development is youthful and mild in the lawn or garden. It is critical to ensure that yearly weeds don’t bloom. The old adage “an ounce of prevention is worth a pound of cure” is highly applicable to weed control. The sooner a weed problem is addressed in the lawn or garden, the easier it is to control. Moreover, the sooner that weed killers are applied, the less product is needed.


Specialized weeding devices make it simpler to kill weeds. Many tools are easily available at local gardening shops that will help control weed problems with any garden or lawn. 

Best Tips for Application of Weed Killers

As far as brawn goes, here’re some more technical strategies one should consider as well:

  • Create a splash zone:

    1. Cut off both ends of the can or the base of a 2-litre plastic jug.
    2. Slip the holder over the weed, embed the sprayer’s spout through the top opening, and spray.
    3. Use an open-finished cardboard box to focus on a bigger weed area.
  • To kill one weed developing in adjacent plants without spraying them:
      1. Cut a little opening in a big piece of plastic.
      2. Lay the plastic over the weed, getting the leaves through the gap.
      3. Apply weed killer.
      4. Wearing gloves, expel the plastic after the herbicide has dried.
      5. Handle the plastic cautiously to abstain from spraying weed killer on wanted plants.
    • Get pinpoint precision by using a paintbrush or glove to apply weed killer to explicit leaves. If utilizing a cotton glove, wear a plastic glove underneath. This keeps the herbicide from getting into contact with the skin.
    • To splash weedy vines without hurting garden plants, follow a bit by bit assault:

      1. Cut the plant at soil level and add a short stake close to the base of the vine.
      2. When the vine resprouts, it’ll begin to climb the vine.
      3. Before development surpasses stake stature, slip an open-finished plastic sack over the weed.
      4. Expel the stake, and shower the weed inside the plastic pack with weed killer.
      5. Try not to remove the sack until the herbicide has dried on foliage.
    • If one inadvertently sprinkles herbicide on the useful plants, leaves should be washed quickly with water. If using foundational herbicide, prune the influenced plant parts immediately and wash the remaining leaves with water.
    • Weed killing products should be sprayed in a calm environment. If the weather is windy, apply it directly on the weed.

  • Take care when killing weeds in a garden with dormant bulbs. The herbicide can seep into the neck of the bulb, causing a reaction in the bulb.
  • Most weed killer companies recommend avoiding spraying weed killer on sunny days, which may worsen the symptoms of spray drift damage. Buy the Sierra Natural Science weed killers work best in full sunlight.
  • Don’t walk on areas that have just been sprayed as it increases the risk of carrying the herbicide into places like lawns, which could kill the grass.
  • Have a dedicated sprayer for the herbicide to prevent accidental application of weed killer to desirable plants.
  • To isolate weeds on the edges of planting beds, use a u-shaped anchor pin to anchor the weed to the ground. Only spray the herbicide after clumping and pinning the foliage.

Final Words

Weeds are one of the biggest nightmares of any gardener, farmer or landscaper. Whether you’re an established gardener and lawn expert or just a newbie trying to nurture their green thumb, Sierra Natural Science provides weed killer and other natural products that vastly outperform homemade remedies in the garden and lawn. Whatever your particular needs are, SNS products are an excellent choice of effective products that are less harmful to the environment, humans and pets.


It’s said that most weed trees will die if one cuts down below the crown as long as they’re young enough to get pruners around them. Is this true?

Not necessarily. In many cases, extra growth will generate below the chopped area. It’s best to dig or pull them out to remove all roots. 

Can weeds be killed by highly acidic vinegar and orange gel?

Vinegar and orange gel can be somewhat effective in killing weeds due to the acid it contains. Be careful not to use it on desirable plants. But the overall effectiveness pales in comparison to the SNS Weed Killer formulas.

What’s the best spray for getting rid of weeds like goat head sticker grass from a play area?

WeedRot™ Natural Systemic Weed Control is pretty all-inclusive when it comes to killing every part of a weed. If one is looking for something less expensive, boiled water might work. But one needs to be aware that both of these will kill any plant they come in contact with.

What are the benefits of knowing weed species growing in the planting bed?

Knowing the type of weed present in one’s garden is crucial to determining the best way to manage it. Some weeds are very aggressive and can be hard to control when they mature. Numerous weed species show a cultural problem on the landscape. For instance, the problem of overwatering is indicated by the presence of nutsedge
