Killing Weeds

This comes rather late in the season, however, it should be filed away, to help you next year



Dr. Knowledge, in 'The Boston Globe' today, asks, and answers, a question that plagues just about anyone;

How do weed killers kill weeds but nothing else?

This is an interesting summer question, and the answer is a bit complex, since there isn’t really a good scientific definition of weed.

Basically, a weed is a plant you don’t want, and a weed killer is something that should kill it. So it all boils down to figuring out what you want to kill and how it’s different from what you want to keep.

You can hit the link to get into all the wonky stuff, about weeds, and the chemicals that kill them.

But Dr. Knowledge does offer an alternative;

Many choices, many herbicides — or you can just pull up what you don’t want by hand and skip a trip to the gym.

Maybe, next year, Dr. Knowledge will ask, and write about, the various muscle creams, and how they work.
