Cheap organic weedkiller

Lemon juice and vinegar both contain acetic acid which can be used to make a very effective organic homemade weed killer.

While most table vinegar's have an acid content of around 5% to 8%, a more concentrated solution of 10% to 15% can be achieved simply by exposing vinegar to the air and allowing it's water content to reduce by evaporation and so increase it's acidity level. The higher the acidity level the more effective your solution will be at killing weeds.

At the right strength this organic weed killer will kill the leaves of any plant it comes into contact with but will not kill its roots, so it's best used on young weeds which will not have enough energy to re-emerge. Repeated spraying can destroy any more established weeds.

You can make your own organic weedkiller by mixing 150 mls of lemon juice and 1 liter of strong vinegar. Vinegar can be bought cheaply at about £1 per liter, so the weedkiller is cheap to make.

Use your mixture to directly spray weeds and the most effective time to do so is during the heat of the day.
