This isn’t so much a question of weed removal as the title suggests as a question about grass growing where it shouldn’t- in my driveway! We have a crushed limestone driveway and the grass loves growing smack down the middle (where the tires do not tread). I grew up with a limestone driveway; I can remember the annual event with my Dad and the ubiquitous yellow poison sprayer to control the driveway. I would like to be more gentle in my application. Any ideas?April 18, 2010 at 11:54 am #29379
What I do here is keep on hand big sheets of plastic, and during hot, sunny stretches, I weight down the plastic with stones on top of the weedy areas and solarize the unwanted growth to death.
You have to leave the plastic in place for a week or two (or preferably more) which is inconvenient parking-wise, but it’s effective. I do this on one stone path in particular. The weakened, “baked” weeds are easy then to dislodge with a big old discarded kitchen knife (or you can keep cooking until they are really goners).
There are also acetic-acid-based herbicides (the stuff in vinegar, but stronger) if you choose to go the sprayer route, but use caution as they are still powerful.May 4, 2010 at 2:23 am #29421
If it is not a large area, you can simply pour a kettle of boiling water over the weeds. Along the same lines, you could buy a flame weeder. This is a torch hooked up to a small propane cylinder. I have not used one to weed, but I have used one to draw images into a lawn, so I know that they kill grass! The grass won’t look dead right away, it will die a few days later (similar to chemical spray). A word of caution: I have read that they are not practical for weeding between plants that you want, because it is easy to accidentally hit and kill something desirable without realizing it.May 7, 2010 at 2:25 am #29427
Once you remove the weeds, you could try using corn gluten as a pre-emergent form of weed control.May 10, 2010 at 12:54 am #29435
My mother did the boiling water routine on weeds and on ground bees nests! I use the regular household vinegar either in a sprayer or straight from the bottle, depending on how much I need to do. It’s fun on a hot sunny day to watch within a few hours to see those babies curl and turn brown. It doesn’t kill to the root, but works good enough for me. It does smell like a salad dressing out there for awhile.May 10, 2010 at 5:35 pm #29437
I’ve used this vinegar combo. Works a little better than straight vinegar as it sticks to the leaves better.
# 4 cups (1 Litre) of white vinegar
# 1/4 cup (50 ml) of table salt
# 2 tsp (10 ml) of your favorite liquid dish soap
# Combine these ingredients in a spray bottle
# Spray it on your weeds in the direct sun on a bright sunny day
