Many of us do not like using weed killer. There are a few alternatives that you can use, in effect making your own weed killer.
Here are 3 simple and effective ways of killing weeds:
Weeds such as dandelions are especially hard to get rid of. On a dry day simply sprinkle salt right in the center of the plant. In a few days the plant will have shriveled up and died. You will be left with a small brown patch but this will return to normal in no time at all.
Spray vinegar directly onto weeds. Be careful not to spray on other plants as they too will die. As before do this on a dry day.
For extra strength you can also add some orange oil extract to the vinegar.
