Q: What is the difference between pulling weeds and weed whacking them?
A: Pulling weeds is the complete removal of the weed (roots and all) and provides a cleaner look to the area, but is also very labor intensive.
Pulling weeds is ideal for flowerbeds and anywhere else you want to be completely weed free.
Weed whacking is simply cutting the weeds with a string trimmer low to the ground (the weeds will still be a couple inches above the ground). Depending on the type of weed (grasses and perennial weeds) will eventually regenerate and will need to be weed wacked again. This is great for large areas where pulling weeds would be very costly.
