Natural and CHEAP Weed Control

Introduction: Natural and CHEAP Weed Control

I made this instructable to provide a option for people to move away from damaging chemical herbicide that destroy our environment everyday. This instructable shows how to make 3 natural, cheap, organic, and simple herbicides made from ingredients readily available at home and also CHEAP. This is a instructable entry for the Get In the Garden Contest.

Step 1: A Shot of Vinegar

If you are tired of hand pulling of broad-leaved weeds(such as dandelions, Plantains, henbits, and Mulleins). Here is a cheap easy solution to your problem

Ingredients and Supplies:
dishwasher liquid(optional)
pump spray bottle

1. Fill the spray bottle with vinegar(or mix 3 parts vinegar to one part dishwashing liquid)
2. Spray in narrow stream
3.Rinse sprayer well after done

TIP: Don't get carried away with this method (repeated applications will acidify the soil)

Step 2: Weeds in Hot Water

Don't you hate scratching and pulling weeds from side or driveway cracks? You can use boiling water to kill these annoying weeds natural, safe, and for cheap. Boiling water kills any plant or seed it touches. This hot water kills any weed seeds it touches!

1. Boil a kettle full of water
2. Pour slowly and carefully, wetting both the weeds and the soil surrounding them.
3. It is as SIMPLE as that

Tip: Leave the cold dead body of the weeds as a deterrent ( mulch) and it'll discourage germination of more weed seeds.

Step 3: Alcohol Attack

Now what can you do with rubbing alcohol? You know what it does it KILLS WEEDS! It's cheap, easy to get, and natural and very effective at killing weeds believe it or not.

Ingredients and Supplies
1 quart water
1 (or more) tablespoons of rubbing alcoho
Measuring cup (1 Quart)

1Mix water and alcohol in the spray bottle (Use 1 tablespoon of alcohol for weed seedlings or thin-leaved weeds and 2 tablespoons or more for tougher weeds).
2. Spray weed leaves thoroughly but lightly (Avoid misting surrounding desirable plants).

Tip: It takes 5 tablespoons of alcohol in a quart of water to wipe out poison ivy for example, and experiment to see how many tablespoons it takes to kill your weeds.

Step 4: Conclusion

These weed killers not only are cheap and effective but are safe to use and don't destroy the environment.

These don't
1. Have farm workers slowly die from inhaling herbicides
2. They don't make you have skin rashes
3. Contaminate our drinking water
4. Make you have headaches
5. Or kill little eagle baby's

    Good but i am not andurstand dittel lastely we kan mix 4 stepes or use indivjual ?

    A method formerly used for sterilizing the working ends of endodontic files and reamers by placing them in a container containing glass beads heated to approximately 225°C (437°F) for a defined period of time. The effectiveness of glass bead sterilizers is very difficult to validate.

    I found an article on EDTA and how sodium EDTA binds to zinc ions necessary for the formation of fungal cell wall. Weakening the cell wall. Thus EDTA could be used (dose dependent) to release Pectinase from the cell wall of certain fungi.

    Oh after a week or two 5% vingear could be sprayed onto the soil to neutalize the ammonia or lye that was used. This could be used to kill poison ivy.

    I am gong to make a herbicide that Is made from Pectinase. This enzyme can be extracted from harmless Penicillium.D cells. Weak acids ph 3 plus digestive enzymes with 7000 RPM with a Centrifuge are required to remove the enzyme.

    The enzyme is stable with 0.1 moles Ammonia hydroxide or sodium hydroxide and EDTA could be used too. Prefer that Ammonia hydroxide be used over lye since it can be converted into other fuel by bacteria and fungi natually found in the soil.

    OK, I have been looking at a lot of these, (yours is some what different but mostly same) {how be it, very helpful}. So, what do you think of this combination?

    vinegar, dishwasher liquid, rubbing alcohol, warm water AND SALT (dissolved in the warm water)

    Exact measurements I don't know yet but.......

    Here is another option for organic weed killing - the Garden Hotshot. Please give it a look and tell me what you think.

    Anyone heard of the "herbicide" where you use Epsom Salts? I believe it uses both epsom salt and alcohol.. but not sure. I've heard it is effective.. but wondering how it works around good plants.. IE, does it 'poison' the ground around it such that the good plants suffer.. or is it just a surface control?

    Oh, p.s. I've never noticed it poisons the ground when you spray, because the amount of salt is pretty minimal. That would be a different story if you were to pour this directly on the ground however. If you want to kill some ground so no weeds or plants ever come back in that spot again for a few years, then by all means, pour it on.

    Yes, but don't use Epsom salts, which is a plant fertilizer, use plain old table salt. Add a cup of salt to a gallon of distilled white vinegar and a squirt of dish soap, mix well (I just add everything to a 1 gal bottle of vinegar as it comes from the store and shake.) Put the mixture in a spray bottle then go spray your weeds at high noon on a sunny hot day. The weeds will be dead in about 10 mins.

    I use 1 cup of rubbing alcohol + 3 cups of water, and a squirt of dish soap to kill insect pests on my plants. Some plants may be a little sensitive to the spray, so do a test area first before you spray the whole plant. I've never had it kill a plant however, at worst you'll probably only get a few dead spots on the leaves of sensitive plants. I wouldn't recommend using this on a sunny hot day, do it early morning or evening (same as you would for any pesticide used on plants.)

    Water is a compound of two elements; oxygen and hydrogen, H2O. Elements are chemicals out of which everything else is made. Therefore everything not only contains chemicals but is made up entirely of them.

    When someone says that something contains chemicals, they usually mean that it contains chemicals that are manufactured by man through a chemical process rather than by nature as in photosynthesis.

    Um, no. Water is a chemical compound, composed of two atoms of hydrogen (an element) and one atom of oxygen (another element).

    I used to love pulling weeds, but now I have over-used my thumb, and pulling out weeds is too painful. I like the boiling water method or simply salt. (

    My father likes to over fertilize the dandylions, thereby killing them - this has issues.

    As for the worms, I HATE them because they eat my plant roots... especially bulbs, and they are not indigenous to the Native US soil, but brought here by the European settlers. The damage done by soil worms to the native plant population is tremendous, altering the majority of the landscape prior to European settlers (from National Geographic Article on Jamestown, maybe 2 years ago).

    If there are less composted material to eat, they will eat roots and bulbs... find them inside my bulbs all the time, because I mulch with pine needles which isn't as yummy as leaf litter.

    Never heard of any earthworm type being bad for the landscape as they only release fertilizer and its a common myth that they eat plant root or bulbs. Worms are great for the ecology of America and the boiling water method is probably the safest for killing weeds
