Organic weedicide and killing weeds is a crucial part of tropical gardening. You may go to a gardening supplier shop and easily buy a chemical weedicide to get rid of weed invaders in your organic garden. But those chemical weedicides may bring more harm to you and your plants than to weeds. So we organic gardeners, let’s go organic and make ourselves some effective and inexpensive organic weedicides.

Vinegar as an organic weedicide

Household vinegar is a good solution to apply while gardening, to kill the weeds. White vinegar with 5% acetic acid (the killer component) is an effective weed killer for our organic gardens (You may go up to 20%). However, we should not use vinegar with high concentrations of acetic acid as it would harm our soil killing all the plants, and probably no new crops will grow in that soil. It is because acetic acid could drop down the pH level of your tropical garden soil. Vinegar is able to kill the weeds by burning them, draining, and ultimately killing them.

Get a sprayer bottle or a garden sprayer, and pour 1 liter of vinegar. Add half a teaspoon of an organic dishwasher or organic soap water. It will make it efficient to adhere to the weed plants. Close the sprayer and shake well before spraying on the weeds. Be careful not to spray on yourself if the concentration of acetic acid is greater than 10% as it could burn you too. This is best to be used when good sunlight is shining upon your organic garden.

Baking soda as an organic weedicide

Another good household organic thing is baking soda which also helps us, organic gardeners, in the process of gardening to eradicate weeds. First, serve the weeds with some water, they’ll be happy. Haha… then bring the devil out. You have to be cautious not to harm your good organic crops with this baking soda treatment. To get rid of the weeds near the organic crops which you have a garden, you can simply sprinkle some baking soda carefully on to the weed after watering them. Otherwise, in a place where you don’t have organic crops, you can get a handful of baking soda and sprinkle it on the area of weed plants. But baking soda on your soil may alter your soil pH. So just try to sprinkle only on the weed. Or else it would be more ideal to get a spray bottle and put water, baking soda, and some dish soap. You can easily spray on weeds after a good shake.


Boiling water to kill weeds

This would be an inefficient way to eradicate weeds completely. But boiling water would burn any plant just like how it could burn us. So if other organic pesticides are unavailable at the moment, you can simply boil a pot full of water and put on the weeds invading your organic gardening process, be careful to avert burning yourself.

Flame and steam does kill weeds

In gardening supplier shops you may have come across flame/weed torches. For small gardens, a torch with a can, or for larger gardens, tanks with the torch will be available in gardening supplier shops. Just like boiling water kills the weeds this also kills the weeds. After a good rain or just water your weeds with a water hose, glide over the torch on top of the weeds. It will boil the water on the weeds killing the weeds by burning.

Likewise, steam machines that are available at local supplier shops can be used to wipe out weeds from your organic garden. Hot steam works more or less similar to that of boiling water treat on weeds and flaming the weeds. It will burn the weeds. Just be cautious to avert injuries to you, kids, and pets.

Oil as s organic weedicide

Oil is one of the best solutions against the weeds which invade our tropical organic gardening. The oil will suffocate plants and kill them. In the presence of good sunlight, oil would burn the weed leaves. In my previous blogs, I have talked about how neem oil would help organic gardening as a pesticide. It also has the property of being a weedicide. Likewise, citrus oil extract, pine oil, cinnamon oil, castor oil, thyme oil, clove oil, lavender oil, and peppermint oil are some of the essential oils which we can use as to kill weeds in our organic gardens. Any biodegradable vegetable oil can be used as a weedicide. You can use a spray can and mix any of these oils with some dish soap. After a good shake, you can apply it to weeds.

Corn gluten is an organic weedicide

Just like baking soda does, corn gluten and cornmeal can be used as a weedicide. But I will not recommend this, because it’s such a big waste of money and food when there is a food crisis going on in some countries like Siberia. Let’s stick with other organic weed killers rather than being a selfish organic gardener.

Combo killer against weeds

I have listed above many potent solutions to kill weeds. So it would be very effective if we combine all those ingredients, making a super-duper combo weed killer. You can combine vinegar, salt, baking soda, other oils, and some dish soap in a sprayer can. Mix well and apply on the weeds in your organic garden.

Also, there are organic weedicides (without chemicals) available in some organic gardening supplier shops. Read carefully the ingredients in the weedicide before buying it. Now go get rid of the weeds popping up in your organic garden either with homemade organic weed killers or ready-made shop items.
