When the weather's nice, everything grows. It's beautiful when flowers burst into bloom; not so lovely when weeds do the same.
If you want to get rid of unsightly weeds but don't want to use toxic chemicals, try these environmentally sound techniques:
Boiling water
Begin by cutting the weeds close to the ground with a pair of garden shears. That weakens the weed and makes it more apt to succumb to super-heated water. Fill a tea kettle with water, and bring it to the boiling point. Pour the boiling water directly into the weeds, and that will be the end of them.
Newspaper
Weeds such as crabgrass and clover need plenty of sunlight. Cover them with a layer of newspaper, and they won't be able to grow. Secure the paper with a few well-placed rocks to keep it from blowing away. It won't take long for the lack of light to kill the weeds.
Salt
If you want to do away with everything that grows in a particular part of your yard, apply salt. Rock salt and table salt are both very effective plant killers. However, use caution because the salt application will make the ground unsuitable for planting anything for a long time.
Vinegar
Vinegar is an effective weed killer that's especially useful for getting rid of dandelions, plantain, burdock, and other weeds with long taproots. Douse the center of the weed with a generous amount of white vinegar, and they'll practically fade before your eyes. You can even use the leftover juice from a jar of pickles to kill pesky weeds.
Yank them!
The most environmentally safe way to do away with weeds involves a pair of gardening gloves and a bit of elbow grease. Pulling weeds is a time-honored tradition and provides healthful exercise, too. Pulling weeds from damp soil is relatively easy, so plan to yank weeds after a rain shower or water your garden.
Try these simple, planet-friendly tricks to rid your lawn and garden of weeds without doing any damage to the environment. And keep your flower garden or trees free of weeds.
