Weed and Feed

Weed and feed fertilizers were developed to make things easier for the homeowner without thought to the environment, human, pet or wildlife health.

Fertilizer and herbicides are not compatible. Fertilizer needs to be watered in quickly so it gets to the grass roots to feed the grass. Herbicides need to penetrate slowly so it stays on the weeds leaf to do its job. Wash it off and it ends up in the ground water as a pollutant.

I will not write here about the health effects of the main weed killer products used in these because there is a large amount of data available on the web about them. The main three herbicides are 2,4-D, MCPP and dicamba and all of them have been linked to possible health problems. Many synthetic fertilizers that are used in producing Weed and Feed fertilizers contain harmful elements in the unregulated portion of their mix.

I have not been able to find any studies that address the chemical compatibility of N-P-K and the various weed killers to see if they combine to create an even more dangerous chemical compounds.

Articles such as the Thurston County Washington on weed and feed http://www.co.thurston.wa.us/health/ehcsg/weed_feed.html tells the story.

Another problem that makes fertilizer and weed killer’s incompatible is that many times the weed killing agent needs to be applied a number of times to be effective. This means over fertilizing to where most of it runs off. Also, if you are not careful you can kill or do major damage to broad-leaf plants you want to grow, such as shrubs and trees.

Some of the herbicides used in these products along with over use of nitrogen can cause major damage to beneficial soil microorganisms, which are necessary for healthy soil.

The possible health effects that this type of synthetic fertilizer can have on your children and pets alone are reason enough to look at alternatives. Canada has banned weed & feed fertilizer use (http://www.hc-sc.gc.ca/cps-spc/pubs/pest/_decisions/rev2010-01/index-eng.php ) for a number of reasons.

Great lawns can be achieved using organic methods with a much reduced chance of health related problems to family and pets plus diminishing environmental pollution. We use a mixture of a liquid fish hydrolysate called MegaGreen for the fertilizer portion

( http://www.multibloom.com/megagreen.html ). It has a mint extract added to it to control the fish odor. With it we apply Turf & Garden Pro for trace elements, beneficial soil biology and lignin.

Weed and Feed fertilizers were developed for connivance of use without consideration of environmental, animal or human health.
