Natural Fertilizer & Weed Killer


Caring for your lawn or garden once meant spreading whatever old fertilizer or weed killer was available. With today's more environmentally conscience gardener demanding more, natural fertilizers and weed killers are in demand. Knowing what to pick, or how to make your own, helps keep your garden green.

Organic Fertilizer

A wide variety of organic fertilizers can be purchased from many garden centers. Look at the label before making a choice, as many fertilizers labeled organic will have a large amount of synthetic materials in them. The percentage of organic matter to synthetic is usually listed on the side of the package.

Seaweed as Fertilizer

Seaweed can be used to fertilize a garden. Washed up seaweed can be collected by hand if you live near a large body of water, or it can be purchased from garden centers. Apply the seaweed directly onto the soil of your garden. It will collect moisture in the garden and bind the soil together. As it decomposes, it will leave a wide variety of nutrients to keep your garden healthy.

Grass Clippings as Fertilizer

Catch the clippings when you mow your lawn. Leave the clippings out to dry after cutting, then apply a thin layer to the garden soil. Dried grass clippings release nitrogen, potassium and phosphorous into the soil. Apply the clippings thinly because grass decomposing in large amounts will release ammonia into your garden.

Vinegar as Weed Killer

A mixture of vinegar and lemon is an effective weed killer in your garden. Combining 4 ounces of lemon juice concentrate and 4 cups white or cider vinegar makes an acidic spray that can be applied to the lawn using a handheld spray bottle. Spray the mixture directly onto the weeds and not onto plants you wish to keep.

Bleach as Weed Killer

A weak bleach solution can also be used to treat weeds in the garden. Mix water and bleach together so that the bleach is only 4 percent of the final mixture. Spraying bleach onto a weed changes its pH balance so that it is alkaline, making it sick. Bleach, after it is sprayed and evaporates in the sun, leaves only a residue of salt and no other harmful chemicals.
