Before I ventured into the world of bees I used to be an avid "roundup" herbicide user. It was much easier to spray weeds than to try to control them. I have assumed a different perspective on the pesticide and herbicide of my life, I don't use either around my acreage anymore. The ways that I combat weed takeover is more diligent cutting of the cotyledons when they sprout from the ground, turning the earth upside down to rid grass growth and as many natural alternatives that I can. I just have a paranoia about herbicide and pesticide. Roundup is one of the least invasive of the herbicides as far as I have investigated, if it is used correctly, and this emphasize. If overspray occurs, it can cause mass devastation of neighbouring "good plants". Once sprayed upon the plant it is quickly assimilated by the vegetative growth and "till under" can be accomplished in 3 days time, providing their is no rainfall. Evidently, according to "roundup" specifications, this product becomes inert once it hits soil. So I hear, but...I don't know about that for sure.
I still will use roundup around my property, but for extremely selective weed kill. I will not spray as I once used to. I will "paint" we shall call it, using a sponge, specific weeds that I know have deep tap roots, like doc. It is an invasive weed that spreads thousands upon thousands of seeds, should the plant come to maturation. This will be a very time consuming project once I begin, but I am willing to spend this moment in time. It is important that herbicides (or pesticides for that matter again), do not come into contact with flowers (or weeds for that matter) that bees may forage upon or near. Not to sound scary, but it is scary stuff, we must be very careful when devilling with chemicals. Best of a great day. Cindi
