How to get rid of:
Uprooting plants by pulling is another effective method to prevent the spread of herbaceous and floating weeds. This is also effective in some shrubs, annuals, and tap-rooted plants. If you're quite hesitant to do it by hand, weed wrenches can be powerful tools to use. This is especially handy (excuse the pun) when you're trying to get a hold of large saplings and shrubs that are too big to be pulled manually. However, weed wrenches are not as effective against many perennial weeds whose stems are buried deep underground and whose roots re-sprout when left behind.
