I have to kill the Canada thistle that is growing where I want to put my new vegetable beds. I have mentioned before that I do not garden 100% organic. One of the big reasons why is Canada thistle. I can’t get rid of the damn stuff. Pulling them out of the ground is the worst thing you can do as the root breaks and 2 thistles grow where one was before. They seem to be impervious to boiling water and bleach. I have even tried regular Roundup to no avail.
Today I bought super-strength Roundup for hard to kill weeds. Those suckers are gonna die.
But super-strength Roundup will kill the plants I want just as fast as it will (hopefully) kill the thistle and there is a slight wind today. So I will be using a soda bottle shield to make sure that the Roundup goes on the thistle and no place else.
Making a soda bottle shield is easy. You will need a regular plastic soda bottle and scissors.
Remove the cap from the soda bottle.
Cut off the bottom of the soda bottle.
Place the soda bottle over the desired target weed.
Spray the lethal Roundup plant toxin into the bottle through the top opening.
The soda bottle will keep the Roundup contained to just the weed and you won’t have to worry about the drift of the Roundup mist landing on the plants you want to keep.
