Weeds is the only plant can grow on the little crack on pavement, driveway or a corner of wall. You had pull it off very frequently and it grow back again within few days; it drive you absolutely mad!
On the supermarket shelves offering all kind of products for removing weeds, but when you think about it, how much chemical you had disposed into the environment because of this little weeds, beside it cost you a lot to buying weeds killer products from the supermarket shelves in long period of time.
I got a cheapest solution for that, and it is easy with no harm to environment at all. The magic ingredient in your kitchen cupboard Bicarbonate of Soda (Baking Soda)
If the weather had been no rain for weeks you might need to moist the ground that the weeds grow on it, then sprinkle bicarbonate of soda. The reason of moisture on the ground is to draw the soda into the roots of weeds.
What does the bicarbonate of soda does to the plant? Bicarbonate of Soda is a neutralization of acid, most ground content acid, when bicarbonate of soda added it will neutralized the acid ground so weeds doesn’t have much food food to absorb from the neutralized ground and starve to death, then you can pull the weeds off easily.
This will last at least about six weeks, if you see any weeds is growing back just repeat the application of bicarbonate of soda.
